Comprehensive Eye Exams
Regardless of your age or physical health, it's important to have regular eye exams.
During a complete eye exam, your eye doctor will not only determine your prescription for eyeglasses or contact lenses, but will also check your eyes for common eye diseases, assess how your eyes work together as a team and evaluate your eyes as an indicator of your overall health.
A comprehensive eye exam includes a number of tests and procedures to examine and evaluate the health of your eyes and the quality of your vision. These tests range from simple ones, like having you read an eye chart, to complex tests, such as using a high-powered lens to examine the health of the tissues inside of your eyes.
Eyecare experts recommend you have a complete eye exam every one to three years, depending on your age, risk factors, and physical condition.
Children. Some experts estimate that approximately 5% to 10% of pre-schoolers and 25% of school-aged children have vision problems. According to the American Optometric Association (AOA), all children should have their eyes examined at 6 months of age, at age 3 and again at the start of school. Children without vision problems or risk factors for eye or vision problems should then continue to have their eyes examined at least every two years throughout school.
Children with existing vision problems or risk factors should have their eyes examined more frequently. Common risk factors for vision problems include:
- Premature birth
- Developmental delays
- Turned or crossed eyes
- Family history of eye disease
- History of eye injury
- Other physical illness or disease
The AOA recommends that children who wear eyeglasses or contact lenses should have their eyes examined at least every 12 months or according to their eye doctor's instructions. Read more about Pediatric Eye Exams.
Adults. The AOA also recommends an annual eye exam for any adult who wears eyeglasses or contacts. If you don't normally need vision correction, you still need an eye exam every two to three years up to the age of 40, depending on your rate of visual change and overall health. Doctors often recommend more frequent examinations for adults with diabetes, high blood pressure and other disorders, because many diseases can have an impact on vision and eye health.
If you are over 40, it's a good idea to have your eyes examined every one to two years to check for common age-related eye problems such as presbyopia, cataracts and macular degeneration.
Because the risk of eye disease continues to increase with advancing age, everyone over the age of 60 should be examined annually.
→ Pediatric Eye ExamsEarly identification of a child's vision problem is crucial.
Pediatric Eye Exams
As a parent, you may wonder whether your pre-schooler has a vision problem or when a first eye exam should be scheduled.
Eye exams for children are extremely important. Experts say 5 to 10% of pre-schoolers and 25% of school-aged children have vision problems. Early identification of a child's vision problem is crucial because, if left untreated, some childhood vision problems can cause permanent vision loss.
WHEN SHOULD KIDS HAVE THEIR EYES EXAMINED?
According to the American Optometric Association (AOA), infants should have their first comprehensive eye exam at 6 months of age. Children then should receive additional eye exams at 3 years of age, and just before they enter kindergarten or the first grade at about age 5 or 6.
For school-aged children, the AOA recommends an eye exam every two years if no vision correction is required. Children who need eyeglasses or contact lenses should be examined annually or according to their eye doctor's recommendations.
Early eye exams also are important because children need the following basic visual skills for learning:
- Near vision
- Distance vision
- Eye teaming (binocularity) skills
- Eye movement skills
- Focusing skills
- Peripheral awareness
- Eye/hand coordination
Because of the importance of good vision for learning, some states require an eye exam for all children entering school for the first time.
SCHEDULING YOUR CHILD'S EYE EXAM
Your family doctor or pediatrician likely will be the first medical professional to examine your child's eyes. If eye problems are suspected during routine physical examinations, a referral might be made to an ophthalmologist or optometrist for further evaluation. Eye doctors have specific equipment and training to help them detect and diagnose potential vision problems.
When scheduling an eye exam, choose a time when your child is usually alert and happy. Specifics of how eye exams are conducted depend on your child's age, but an exam generally will involve a case history, vision testing, determination of whether eyeglasses are needed, testing of eye alignment, an eye health examination and a consultation with you regarding the findings.
After you've made the appointment, you may be sent a case history form by mail, or you may be given one when you check in at the doctor's office. The case history form will ask about your child's birth history (also called perinatal history), such as birth weight and whether or not the child was full-term. Your eye doctor also may ask whether complications occurred during the pregnancy or delivery. The form will also inquire about your child's medical history, including current medications and past or present allergies.
Be sure to tell your eye doctor if your child has a history of prematurity, has delayed motor development, engages in frequent eye rubbing, blinks excessively, fails to maintain eye contact, cannot seem to maintain a gaze (fixation) while looking at objects, has poor eye tracking skills or has failed a pediatrician or pre-school vision screening.
Your eye doctor will also want to know about previous ocular diagnoses and treatments involving your child, such as possible surgeries and glasses or contact lens wear. Be sure you inform your eye doctor if there is a family history of eye problems requiring vision correction, such as nearsightedness or farsightedness, misaligned eyes (strabismus) or amblyopia ("lazy eye").
EYE TESTING FOR INFANTS
It takes some time for a baby's vision skills to develop. To assess whether your infant's eyes are developing normally, your eye doctor may use one or more of the following tests:
- Tests of pupil responses evaluate whether the eye's pupil opens and closes properly in the presence or absence of light.
- "Fixate and follow" testing determines whether your baby can fixate on an object (such as a light) and follow it as it moves. Infants should be able to perform this task quite well by the time they are 3 months old.
- Preferential looking involves using cards that are blank on one side with stripes on the other side to attract the gaze of an infant to the stripes. In this way, vision capabilities can be assessed.
EYE TESTING FOR PRE-SCHOOL CHILDREN
Pre-school children can have their eyes thoroughly tested even if they don't yet know the alphabet or are too young or too shy to answer the doctor's questions. Some common eye tests used specifically for young children include:
- LEA Symbols for young children are similar to regular eye tests using charts with letters, except that special symbols in these tests include an apple, house, square and circle.
- Retinoscopy is a test that involves shining a light into the eye to observing how it reflects from the retina (the light-sensitive inner lining of the back of the eye). This test helps eye doctors determine the child's eyeglass prescription.
- Random Dot Stereopsis uses dot patterns to determine how well the two eyes work as a team.
EYE AND VISION PROBLEMS THAT AFFECT CHILDREN
Besides looking for nearsightedness, farsightedness and astigmatism (refractive errors), your eye doctor will be examining your child's eyes for signs of these eye and vision problems commonly found in young children:
- Amblyopia. Also commonly called "lazy eye," this is decreased vision in one or both eyes despite the absence of any eye health problem or damage. Common causes of amblyopia include strabismus (see below) and a significant difference in the refractive errors of the two eyes. Treatment of amblyopia may include patching the dominant eye to strengthen the weaker eye.
- Strabismus. This is misalignment of the eyes, often caused by a congenital defect in the positioning or strength of muscles that are attached to the eye and which control eye positioning and movement. Left untreated, strabismus can cause amblyopia in the misaligned eye. Depending on its cause and severity, surgery may be required to treat strabismus.
- Convergence insufficiency. This is the inability to keep the eye comfortably aligned for reading and other near tasks. Convergence insufficiency can often be successfully treated with vision therapy, a specific program of eye exercises.
- Focusing problems. Children with focusing problems (also called accommodation problems) may have trouble changing focus from distance to near and back again (accommodative infacility) or have problems maintaining adequate focus for reading (accommodative insufficiency). These problems often can be successfully treated with vision therapy.
- Eye teaming problems. Many eye teaming (binocularity) problems are more subtle than strabismus. Deficiencies in eye teaming skills can cause problems with depth perception and coordination.
VISION AND LEARNING
Experts say that 80% of what your child learns in school is presented visually. Undetected vision problems can put them at a significant disadvantage. Be sure to schedule a complete eye exam for your child prior to the start of school.
→ OptomapThe optomap ultra-widefield digital retinal imaging device helps you and your eye doctor make informed decisions about your eye health and overall well-being. Combining your eye doctor's expertise and optomap technology, optomap brings your eye exam to life.
Protect your vision
We recommend that our patients include an optomap as part of your comprehensive eye exam today.
The optomap ultra-widefield digital retinal imaging device helps you and your eye doctor make informed decisions about your eye health and overall well-being. Combining your eye doctor's expertise and optomap technology, optomap brings your eye exam to life.
What is your retina?
The retina is a delicate lining at the back of the eye similar to film in a camera.
Light strikes the retina through the lens in your eye and produces a picture which is then sent to the brain, enabling you to see.
Why is a healthy retina important?
An unhealthy retina cannot send clear signals to your brain which can result in impaired vision or blindness. Mast retinal conditions and other diseases, can be treated successfully with early detection.
Without a comprehensive eye exam, you may not be aware of a potential problem. You may see clearly, and because the retina has no nerve endings, you may not feel any pain, a symptom which may otherwise prompt you to see your doctor.
Do all eye doctors have an optomap ultra-widefield digital retinal imaging system?
Optomap is a standard of care for evaluating eye health in this office and millions of people worldwide have benefited from optomap.
How often should I have an optomap?
Your doctor will advise you based on your individual circumstances, but the general recommendation is that you have an optomap every time you have an eye exam. This will ensure you have a digital record of your retinal health on file which can be compared for changes over time.
Should my children have an optomap too?
Many vision problems begin at an early age, So it's important for children to receive proper eye care from the time they are infants .
Will I need to be dilated and does it hurt?
An optomap takes only seconds to perform, is not painful, and typically does not require dilation. However, your eye doctor may decide dilation is still needed.
More than 50 million optomaps have been performed worldwide since 2000.
How does your eye doctor normally examine the retina?
Your eye doctor looks through your pupil to examine the back of your eye. Traditional viewing methods can be effective, but difficult to perform and are carried out manually without any digital record.
How does the optomap help?
The optomap ultra-wide digital retinal imaging device captures more than 80% of your retina in one image. Traditional methods typically reveal only 10-45% of your retina at one time.
The unique optomap ultra-widefield view enhances your eye doctor's ability to detect even the earliest sign of disease that appears on your retina. Seeing most of the retina at once allows your eye doctor more time to review your images and educate you about your eye health. Numerous clinical studies have demonstrated the power of optomap as a diagnostic tool.
→ Corneal MappingA non-invasive medical imaging technique for mapping the surface curvature of the cornea, the outer structure of the eye.
Corneal topography, also known as photokeratoscopy or videokeratography, is a non-invasive medical imaging technique for mapping the surface curvature of the cornea, the outer structure of the eye. Since the cornea is normally responsible for some 70% of the eye's refractive power, its topography is of critical importance in determining the quality of vision.
The three-dimensional map is therefore a valuable aid to the examining ophthalmologist or optometrist and can assist in the diagnosis and treatment of a number of conditions; in planning refractive surgery such as LASIK and evaluation of its results; or in assessing the fit of contact lenses. A development of keratoscopy, corneal topography extends the measurement range from the four points a few millimeters apart that is offered by keratometry to a grid of thousands of points covering the entire cornea. The procedure is carried out in seconds and is completely painless.

→ Digital Retinal ImagingUsed to detect diseases such as diabetes and macular degeneration, it is critical to confirming the health of the retina, optic nerve and other retinal structures.
Digital Retinal Imaging
Digital Retinal Imaging allows your eye doctor to evaluate the health of the back of your eye, the retina. It is used to detect diseases, such as, Diabetes and Macular Degeneration. It is critical to confirm the health of the retina, optic nerve and other retinal structures.
Many eye diseases, if detected at an early stage, can be treated successfully without total loss of vision. Your Retinal Images will be stored electronically. This gives the Doctor a permanent record of the condition and state of your retina. This is very important in assisting the Doctor to detect and measure any changes to your retina each time you get your eyes examined, as many eye conditions, such as Glaucoma are diagnosed by detecting changes over time.
→ Dry Eye TreatmentDry eyes result from the chronic lack of lubrication and moisture on the surface of the eye, which can cause minor irritations, an inability to wear contact lenses and an increased risk of corneal inflammation and eye infections.
TREATMENTS FOR DRY EYE
Dry eyes or dry eye syndrome (DES) is an ongoing condition that treatments may be unable to cure. But the symptoms of dry eye—including dryness, scratchiness and burning—can usually be successfully managed.
Your optometrist may recommend artificial tears, which are lubricating eyedrops that may alleviate the dry, scratching feeling and foreign body sensation of dry eye. Prescription eye drops for dry eye go one step further: they help increase your tear production.
If you wear contact lenses, be aware that many artificial tears cannot be used during contact lens wear. You may need to remove your lenses before using the drops. Wait 15 minutes or longer (check the label) before reinserting them. For mild dry eye, contact lens rewetting drops may be sufficient to make your eyes feel better, but the effect is usually only temporary. Switching to another lens brand could also help.
Check the label, but better yet, check with your doctor before buying any over-the-counter eye drops. Your eye doctor will know which formulas are effective and long-lasting and which are not, as well as which eye drops will work with your contact lenses.
To reduce the effects of sun, wind and dust on dry eyes, wear sunglasses when outdoors. Wraparound styles offer the best protection.
Indoors, an air cleaner can filter out dust and other particles from the air, while a humidifier adds moisture to air that's too dry because of air conditioning or heating.
For more significant cases of dry eye, your eye doctor may recommend punctal plugs. These tiny devices are inserted in ducts in your lids to slow the drainage of tears away from your eyes, thereby keeping your eyes more moist.
Doctors sometimes recommend special nutritional supplements containing certain essential fatty acids to decrease dry eye symptoms. Drinking more water may also relieve symptoms.
If medications are the cause of dry eyes, discontinuing the drug generally resolves the problem. But in this case, the benefits of the drug must be weighed against the side effect of dry eyes. Sometimes switching to a different type of medication alleviates the dry eye symptoms while keeping the needed treatment. In any case, never switch or discontinue your medications without consulting with your doctor first.
Treating any underlying eyelid disease, such as blepharitis, helps as well. This may call for antibiotic or steroid drops, plus frequent eyelid scrubs with an antibacterial shampoo.
If you are considering LASIK, be aware that dry eyes may disqualify you for the surgery, at least until your dry eye condition is successfully treated. Dry eyes increase your risk for poor healing after LASIK, so most surgeons will want to treat the dry eyes first, to ensure a good LASIK outcome. This goes for other types of vision correction surgery, as well.

→ Eye EmergenciesEye injuries range from the very minor such as getting soap in your eye, to the catastrophic such as chemical exposures or lacerations, which could result in permanent loss of vision. Find out when to seek immediate medical care.
WHEN TO SEEK MEDICAL CARE
In most cases, if you have continuing symptoms of pain, visual disturbance, or bleeding, you should go to an ophthalmologist (a medical doctor who specializes in eye care and surgery).
In general, if you are not sure if you have a serious eye injury, call your ophthalmologist for advice.
CALLING YOUR OPHTHALMOLOGIST MAY BE HELPFUL IN THE FOLLOWING CIRCUMSTANCES:
Chemical exposures: If you are not sure if the exposure is potentially serious, you have washed out your eye, and you have few symptoms, then your ophthalmologist may be able to help you decide whether or not you should be seen immediately.
Subconjunctival hemorrhage: If you are not sure that you have this condition, your ophthalmologist may be able to help with the diagnosis. This condition does not require immediate medical attention.
Continuing pain and decreased vision after an eye injury can be warning signs that require prompt medical attention. If you have an ophthalmologist, he or she may be able to take care of you in the office. Otherwise, go to a hospital's emergency department.
THE FOLLOWING CONDITIONS SHOULD BE SEEN PROMPTLY BY AN OPHTHALMOLOGIST OR IN THE EMERGENCY DEPARTMENT:
Chemical exposures: If the substance was known to be caustic, immediate medical evaluation by either an ophthalmologist or in the emergency department is needed, regardless of symptoms. Acids and alkalis are the worst and require immediate attention. If the substance is not dangerous, such as soap or suntan lotion, a visit to the emergency department is not necessary, but a visit to the ophthalmologist's office may be helpful to alleviate any remaining symptoms. When in doubt, seek medical attention.
Lacerations: Cuts that affect the eyelid margins (where the eyelashes are) or the eyeball itself need immediate medical attention. Foreign bodies that are not removed with gentle washing should be evaluated by an ophthalmologist.
Solar retinopathy: Evaluation by an ophthalmologist is necessary. This is one condition where there is little that can be done in the emergency department.
→ Glaucoma TestingGlaucoma testing involves measuring internal eye pressure and a detailed scan of the retina for signs of disease.
WHAT IS A GLAUCOMA TEST?
Glaucoma is the generalized name for a group of eye diseases that damage the optic nerve of the eye, preventing the eye from sending accurate visual information to the brain. Glaucoma tests are designed to test your eyes for one of the key symptoms of the disease—increased eye pressure—however only a comprehensive eye exam can reveal whether or not you have glaucoma. Increased pressure inside the eye is often a key indicator of glaucoma, though not exclusively so. Eye doctors can use a number of tests for eye pressure, but will, by default, check for signs of glaucoma as part of a detailed examination of the retina—the light sensitive area at the back of the eye responsible for processing images.
HOW DOES GLAUCOMA TESTING WORK?
A glaucoma test is usually part of a routine eye exam. Both types of glaucoma tests measure internal pressure of the eye.
One glaucoma test involves measuring what happens when a puff of air is blown across the surface of the eye. (A puff test) Another test uses a special device (in conjunction with eye-numbing drops) to "touch" the surface of the eye to measure eye pressure.
While increased eye pressure is a key indicator of the disease, it does not necessarily mean you have a glaucoma diagnosis. In fact, the only way to detect glaucoma is to have a detailed, comprehensive eye exam that often includes dilation of the pupils.
So "true" glaucoma testing actually involves examining the retina and optic nerve at the back of the eye for signs of the disease. Glaucoma can cause slight to severe vision loss, and is often discovered only after the disease is present—that's why glaucoma testing is so important.

→ Low VisionLow vision is the term used to describe reduced eyesight that cannot be fully corrected with eyeglasses, contact lenses or eye surgery. The primary causes of low vision are eye diseases, but low vision also can be inherited or caused by an eye or brain injury.
A person with low vision is not blind: they have some useful sight. But the degree of their visual impairment can make daily tasks, such as reading and driving, difficult or impossible. Though children as well as adults can be visually impaired, low vision is mostly a problem that afflicts seniors. Vision loss after a lifetime of good eyesight can be very traumatic, leading to frustration and depression.
Many people who develop eye problems that cause low vision lose their jobs. According to Lighthouse International, among visually impaired Americans of ages 21 to 64, only 43.7% are employed. Among normally-sighted people in this age group, 80% are employed.
Not being able to drive safely, read quickly, or easily see images on a television or computer screen can cause people with low vision to feel shut off from the world. They may be unable to get around town independently, earn a living or even shop for food and other necessities. Some visually impaired people become completely dependent on friends and relatives, while others suffer alone.
Thankfully, in many cases, people with impaired vision can be helped by low vision devices, which include eyeglass-mounted magnifiers, handheld magnifiers and telescopes, and stand-alone magnifiers. There are many ingenious low vision devices and strategies that can help visually-impaired individuals get the most out of their remaining sight and, in many cases, continue to live independently.
If you have hazy or blurred vision, light sensitivity, loss of peripheral vision, night blindness, a need for more light than before, unusual floaters or spots, or difficulty reading - your first step is to see an eyecare professional for a complete exam.
These could be the first signs of a serious eye disease such as macular degeneration, glaucoma, or retinitis pigmentosa. Or, they could mean you are developing a cataract that needs removal. Whatever the case, it's wise to take action before further vision loss occurs.
If your eye doctor finds you have a vision loss that cannot be corrected with eyewear, medical treatment or surgery, they can refer you to a low vision specialist. Usually an optometrist, a low vision specialist can evaluate the degree and type of vision loss you have, prescribe appropriate low vision aids, and help you learn how to use them.
The low vision specialist can also recommend non-optical adaptive devices, such as large-print books, audio tapes, special light fixtures and signature guides for signing checks and documents. If necessary, your eye doctor or low vision specialist can also refer you to a counselor to help you cope with your loss of vision. www.enhancedvision.com/low-vision-product-line/acrobat-lcd-desktop-video-magnifier.html
→ Macular Degeneration TreatmentMacular degeneration is an eye disease that affects the portion of the eye responsible for processing fine detail and providing sharp central vision (called the macula).
MACULAR DEGENERATION TREATMENT
There is currently no cure for macular degeneration. Macular degeneration treatment options exist that can slow the progress of the disease or improve vision based on the type of macular degeneration you are experiencing. To understand the risks and the limitations of all macular degeneration treatments, speak frankly with your eye doctor.
Dry macular degeneration treatment actually begins with routine eye exams, especially after age 60. The goal here is to catch the development of ARMD early. If detected, you may be prescribed a specific mix of high-dose zinc and antioxidants that have shown an ability to slow the progression of the disease.
Wet macular degeneration treatment can include a number of options; including laser surgery, light-activated dyes that are injected into the circulatory system, or drugs injected directly into the eye that inhibit the growth of abnormal blood vessels that cause the wet form of the disease.
With any macular degeneration treatment, there are no guarantees that the disease can be stopped, no promises that a treatment won't need to be repeated, and a sobering reminder that vision, once lost, is rarely restored.

→ Sports and Specialty Eyewear FittingSports eyewear can give you the performance edge you're seeking for just about any sport (tennis, racquetball, etc.) or recreational activity (hunting, fishing, etc.). It can also provide the safety and eye protection you need as well.
SPORTS AND SPECIALTY EYEWEAR FITTING
Seeing "20/20" isn't the only measure of good vision. Visual acuity (20/20, etc.) is certainly important. But good vision involves a set of several skills, including depth perception, peripheral visual field awareness, eye-hand coordination and more.
All these vision skills are extremely important in sports, whether you play golf, soccer, baseball, basketball or racquet sports.
If you want to perform your best in sports, you may benefit from seeing an eyecare practitioner who specializes in sports vision - even if you already have 20/20 vision. This is because a typical eye exam usually doesn't include tests of visual skills important to sports performance.
Sports vision testing is more extensive, and can be tailored to the specific sport you are interested in. During a sports vision exam, it's not unusual for the examiner to include tests to evaluate how well you see while you are moving around outdoors and interacting with other objects or players.
Many professional athletes work on their sports vision, but so do high school and college athletes, recreational golfers, tennis players and even billiards players. Some non-sports professionals also benefit from the same vision training, including law enforcement personnel and pilots.
When you visit a sports vision specialist, he or she will probably give you a complete eye exam and will ask you questions about your activities. More testing will determine your sports-related needs. These tests may include the use of three-dimensional, holographic images so you can react to them as in real life, and computerized tests that measure your reaction time and eye-hand coordination.
Depending on your particular sport, actual on-field measuring of your reactions to various sports situations may be included. Many sports vision specialists will attend your games or matches to help them evaluate your vision performance. They may also study videos of your games.
You may need only one visit to a specialist to set you on your way to better visual skills for sports. However, in many cases, a comprehensive sports vision training program is a better option to help you develop your sports vision skills so they become second nature.

→ Visual Field TestingMeasures the quality of your side vision (peripheral vision). Usually involves covering one eye and focusing the other on a fixed point in front of you, while describing what you can see on the "periphery" of your vision.
VISUAL FIELD TESTING
A visual field test measures how much 'side' vision you have. It is a straightforward test, painless, and does not involve eye drops. Essentially lights are flashed on, and you have to press a button whenever you see the light. Your head is kept still and you have to place your chin on a chin rest. The lights are bright or dim at different stages of the test. Some of the flashes are purely to check you are concentrating.
Each eye is tested separately and the entire test takes 15-45 minutes. Your optometrist may ask only for a driving licence visual field test, which takes 5-10 minutes. If you have just asked for a driving test or the clinic doctor advised you have one, you will be informed of the result by the clinic doctor, in writing, in a few weeks.
Normally the test is carried out by a computerised machine, called a Humphrey. Occasionally the manual test has to be used, a Goldman. For each test you have to look at a central point then press a buzzer each time you see the light.
