Most of the observable changes in your eyes occur over periods of months to years. To record these observations, doctors have had to rely on drawings made by hand, with their inherent limitations.
In just a few seconds a high resolution, wide-angle photograph becomes part of your permanent ocular health record to aid in diagnosis now, and years from now. Should you move from the area, copies of these photographs can be forwarded to your new doctor for future evaluation and comparison.
Below are examples of photographs obtained by our equipment using this technique. They illustrate graphically the differences seen in a normal retina as compared to diseased retinas.
The Optomap takes just minutes to perform; it is fast, painless, and comfortable for patients. It is particulary helpful when you return fro your annual exam as it provides a permanent record of the conditionof your retina. Dr. Schatz will compare each year's Optomap image side by side to discover even subtle changes and monitor your continuing eye health. Early detection of retinal disorders is critical to preventing serious progression and loss of vision.
Become Better Informed
The Optomap Retinal Exam is a valuable tool when used by the doctor to educate you about your health and wellness. It provides you and your doctor with an opportunity to interactively review and discuss the results of your exam. The doctor will educate you on the various structures of the retina and explain treatment options for any conditions revealed by the exam. The more knowledgeable you are about eye diseases, the more likely you will understand and follow the doctor's recommendations for treatment and prevention.
Protect Your Family's Vision
We all want to protect our vision. That is why it is important for people of all ages to have annual eye examinations that include the clinical evaluation of your retina - annual exams are vital to maintaining your vision and overall health.
From children to seniors, the Optomap allows the doctor to view your retina quickly and in a noninvasive manner. Your doctor highly recommends that you have an Optomap Retinal Exam Today.
Eye Disease Statistics
- Every five seconds one person in the world goes blind. A child goes blind every minute.*
- 80% of blindness is avoidable (60% treatable, 20% preventable).*
- People over the age of 65 have a 30% chance of developing age-related macular degeneration. It is the leading cause of blindness for those aged 65 and older.*
- Blindness is the number one complication of people with diabetes.**
- More than 1.1 million Americans are legally blind. An additional 50,000 people lose their site each year.**
- Approximately 2.2 million Americans over 40 years have glaucoma, yet more than half are unaware they have this disease until their site is compromised.**

These ultra widefield images below were captured in a single image without dilation in only a quarter of a second.
This is a small selection of the types of pathology detected during the Optomap Retinal Examination.
What is dilation of your eyes?
To dilate your eyes, your optometrist uses drops to cause your pupils, the black spots which are openings, to enlarge. With your pupils dilated, your optometrist has a better opportunity to examine the inside of your eyes.
Who should have their pupils dilated?
If you are a patient new to a practice or have a personal or family history of eye health problems, your optometrist may suggest dilating your eyes. Certain conditions may increase your risk for eye health problems. For example, if you are diabetic or highly nearsighted, your optometrist may recommend a dilated examination. Your age and other factors may also indicate to your doctor that dilation is needed.
Who should not have their pupils dilated?
Based on your current and past health, any allergies you might have or any medication you may be taking, your optometrist will determine if your eyes should not be dilated. Be sure to tell your doctor about any allergies, reactions to drugs or health problems you have had.
What drugs are used to dilate?
Drugs called mydriatics are used, the specific type and strength depending on your own individual needs.
How long does dilation take?
The current drugs used to dilate are fast-acting. Dilation usually occurs in 20 to 45 minutes.
How long will it last?
With some exceptions, the effects usually last from four to six hours.
What does the doctor see?
Imagine looking into a room through a partially opened door. You only see a portion of the room. But if the door is open wide, you can see much more of the room. By enlarging the pupil and using certain instruments, your doctor is able to see more of the structures inside your eye. If you have certain signs or symptoms, the doctor will have a better chance of detecting their cause by seeing more of the inside of your eye. This is especially true if the disease or condition is located peripherally along the side of your eye.
What are the side effects, if any?
Most people encounter few, if any, side effects. Dilation may cause you to experience glare, some sensitivity to light and some blurring of your near vision and may affect your ability to drive. If you are uncomfortable about this, arrange for someone to come along with you to drive you home.
Just a reminder
To reduce problems with light sensitivity and glare following dilation, bring along a pair of sunglasses. If you wear contact lenses, bring your backup glasses; your doctor may want you to wear them until dilation has worn off.
Dilation can lead to healthier eyes
Dilation can help your optometrist tell if your eyes are healthy. Dilation is very safe and its unlikely that you will experience much inconvenience or discomfort. Dilation, when needed, provides you with the most thorough eye health examination possible. You and your eyes will be healthier for it.
Although our practice is tailored to the contact lens patient, many of our patients are pleased to learn that we provide a number of other services.
It is generally accepted that a routine eye examination should include a refraction for determining prescription changes, a test for ensuring the health of the eye's interior, and a test for glaucoma. However, another important part of a complete eye examination for adults is Visual Field Testing. A visual field test measures the ability of the eye to see peripherally and indicates that the entire visual system is functioning properly. Most patients who come in for eye examinations do so because of impaired vision. When you direct your focus to a fixed point, you actually move a small area on the retina, called the fovea, into line with the fixation point. The fovea is the only part of the back of the eye that has the ability to see clearly. Often the entire eye examination is an attempt to determine the correction that would improve the visual path to this small area.
Most people take for granted what the eye sees—the total visual field. The patient usually is unaware of problems, or blind spots, in the visual field. For example, very few people are aware that every normal eye has a blind spot in the retina, at the point where the optic nerve enters. Other blind spots can develop as the result of some systemic bodily dysfunction or the growth of a tumor. Quite commonly a blind spot is the first symptom that something is wrong. Unfortunately, it often goes unnoticed. Because manual visual field plotting is time consuming and expensive, it has not been included as part of a routine examination. Properly performed, however, no supplemental vision test is more important as an aid to early detection of visual abnormalities and blind spots symptomatic of other problems. It is therefore recommended that this test be performed routinely on all patients over age 30 and on any other patients presenting any symptoms warranting further investigation.
Now, Automatic Visual Field Plotting can be done in a fraction of the time and at a fraction of the expense of its manual counterpart. A new, computer-controlled instrument electronically plots your visual field, resulting in highly accurate, permanent records for both eyes. Any visual field problems will be detected. If the plots are normal, they provide an excellent reference for evaluating changes revealed in subsequent tests.
With this new sophisticated addition to our testing sequence, we are able to provide our patients with an important visual examination not usually performed. This extra measure of care is your assurance that your total visual health is our concern.
The corneal topographer system is an electro-optical instrument capable of measuring the shape and contour of the cornea in very fine detail.. This very sophisticated instrument analyzes data collected from images of the eye using two separate algorithms providing us with very fine details regarding the condition of the corneal surface. It also is very usefull in diagnosing various forms of corneal dystrophy and other corneal abnormalities.
It is generally accepted that a routine eye examination should include a refraction for determining prescription
changes, a test.
Pachymetry is an examination procedure that measures the thickness of the cornea. This information is extremely important in the diagnosis and management of some forms of corneal disease, for patients contemplating Lasik, for aid in the diagnosis and management of Glaucoma, and in managing many other ocular conditions.
Although MPPD naturally declines as we grow older, deficiencies can occur at any age. A reduced MPPD can increase a patient’s risk factors for the development of macular degeneration. The Macuscope can uncover risk for macular disease years or even decades before any symptoms of macular disease appear. Measuring MPPD allows the doctor to classify patients into one of three categories: High Risk, Low Risk, or Average Risk.
Patients in the High Risk category, with low macular pigment can be prescribed a treatment program with ocular supplements which can increase the pigment density of the macula, thus reducing their risk for the development of macular degeneration.
High-Order Aberrations are more complex vision disorders. The most common of these include coma, trefoil, spherical aberration, and chromatic aberration. These forms of vision errors have traditionally been ignored by eye care professionals because their impact on vision was believed to be slight, and because prior to Wavefront Aberrometry no feasible means of precisely measuring or correcting them existed.
This technology creates an aberration map of the eye by comparing the shape of the captured wavefront with that of the pre-programmed reference wavefront considered to represent a theoretically perfect eye. The eye doctor uses the patient’s wavefront map as a blueprint for custom-designing his or her vision correction with any and all forms of vision correction available.
Sight threatening diseases such as Glaucoma, Macular Degeneration, Diabetic Retinopathy and others generally have no outward signs or symptoms in their early stages. It is for this reason that annual comprehensive eye examinations, including a thorough retinal evaluation are essential to protecting your eyes and vision. Our practice has, therefore, designed a complete iWellness Screening Program utilizing all of our state-of-the-art technology. Incorporating this instrumentation into our exam routine helps us to provide our patients with the highest level of eyecare possible.
