What is Low Vision Optometry?
In most cases a patient who has been given the title of low vision patient is one that has had a disease (senile macular degeneration, diabetic retinopathy, cystoid macular edema) that has reduced their best corrected visual acuity (vision with glasses or contact lenses) to a point where they require magnification just to be able to get them to a functioning level (less than 20/50 on an eye chart). This increased magnification can affect their mobility and reading range where they might need training to function visually. The philosophy of low vision correction is not new but our doctors employ a model which is very patient friendly (we don’t just prescribe glasses and hope that you adapt). Regular eye doctors may not be familiar with devices or what can be done to restore visual independence. Vision rehabilitation is all about helping patients maximize their remaining vision and develop strategies that will lead them to a more independent life style. It includes setting realistic expectations and determining which activities are the most important and most achievable. As a result, much of the rehabilitation is very task specific. It’s not unusual for us to ask the seemingly simple question: “What do you most want to do?” The result is often a recommendation for more than one device because each is designed to serve a very specific purpose. Below we’ll list for you the services that we provide for our low vision patients:
Optical Aids Evaluation- following extensive trial frame refraction, all patients are evaluated by us in each of 12 categories of optical aids including those for distance and near vision.
Visual Rehabilitation Therapy- Therapy is performed in the following areas before final prescription/purchase:
All Optical aids
Task lighting (incandescent, fluorescent, halogen, combination, natural)
Glare/Contrast filters (clip-on, flip up, wrap, prescription)
Activities of daily living (stove dials, cooking, pouring liquids, self care, handling money, etc.)
Community reintegration (directory assistance exemption, large print, talking books, etc.)
In Home Therapy (Home Visits)- This is an option for all patients but must first be approved by their insurance carrier.
State of the Art Low Vision Devices- We have the most innovative adaptive equipment in all of the areas listed above as well as in Assistive Computer Technology.
Special Services Assistance- We work with the Bureau of Blindness and Visual Services and the Office of Vocational Rehabilitation when a patient has financial need and meets the state agencies criteria.
Define Optical Insurance Plans- We help interpret optical insurance plans to determine if there is any coverage for your low vision devices.
In Home Delivery and Set-Up- We provide in home delivery and set-up of the prescribed in-line video magnifiers.
Our philosophy regarding low vision patients and our visual rehabilitation model is very progressive. We have devoted our careers to refining the model to optimize successful outcomes for our patients.
What is a Visual Field Test and why is is useful?
Visual field testing is a process to determine defects in the field of vision and tests the function of the retina, optic nerve and optic pathways. Visual field testing can assist us in early detection of glaucoma, retinal or neurological diseases (such as brain tumors and optic nerve disease) and enables us to better diagnose causes of headaches, migraines or vertigo. The stabilization or progression of glaucoma can be monitored only by a visual field examination. The frequency of a visual field examination for a glaucoma patient is dependant on the variability of the intraocular pressure (glaucoma test) measurements, the appearance of hemorrhages on the optic nerve head and the progressive “cupping” of the optic nerve. A patient is considered a glaucoma suspect as evidenced by an increase in intraocular pressure, asymmetric measurements of greater than 2-3 mmHg between eyes or has an optic nerve head suspicious of glaucoma. Visual field testing is appropriate for diagnosing intracranial hemorrhages, or tumors. Our visual field testing device uses a computer system that incorporates the Zippy Estimation of Sequential Thresholds (ZEST) using Frequency Doubling Technology which has demonstrated superior sensitivity, specificity and reproducibility while decreasing the testing time by half. By utilizing this technology, and others, our goal is to preserve and enhance the vision of our patients.
What is Digital Retinal Imagery and why is it important?
This new technology combines retinal photography with computerized imaging to allow instant viewing of the retina and optic nerve in great detail. Both the doctor and the patient see the images on the computer monitor.
This method of examining and documenting the retina promotes earlier diagnosis of abnormal conditions such as Macular Degeneration, Glaucoma and Diabetic Retinopathy. This procedure could allow us to prevent permanent vision loss by diagnosing eye disease at an earlier stage. An additional benefit of retinal imaging is that we can store the pictures permanently and compare them against any changes in the future.
What is Diabetes and how does it affect your eyes?
Diabetes mellitus (DM) is a chronic, multi-system disease. Diabetes complications in the eye include diabetic retinopathy (DR), dry eye, cataracts, optic disc disease, as well as eye muscle, pupil, and eyelid involvement. DM is the leading cause of new-onset blindness in working-aged Americans, despite proven methods of care and treatment. The value of comprehensive eye examinations by an optometrist or ophthalmologist and appropriate treatment is well documented. For these reasons, the American Diabetes Association Clinical Practice Recommendations, the American Optometric Association Optometric Clinical Practice Guideline on Care of the Patient With Diabetes, and the American Academy of Ophthalmology Preferred Practice Pattern for Patients with Diabetes all recommend an annual dilated comprehensive eye examination for patients with DM.
Through a comprehensive examination, our office not only detects and diagnoses possible ocular complications of DM including cataracts, glaucoma, retinopathy, and refractive error, but also establishes a recommended treatment plan for each patient. The examination also provides another opportunity to educate the patient and reinforce the importance of appropriate blood glucose control, blood pressure control, and discussion of other risk factors. Currently, only 62% of patients with DM receive an annual dilated eye examination by an optometrist or ophthalmologist..
Digital retinal imaging systems may be a useful tool to increase access and adherence to demonstrated standards of care among individuals with DM. This imaging does not replace a comprehensive eye examination by an optometrist.
Controlling your blood sugar level via proper diet, exercise, and medication, having yearly comprehensive and dilated eye examinations, and having photographs taken of the back part of your eyes are the best ways to minimize your risk of these serious and sight threatening effects of diabetes. The unfortunate reality of such effects on the eyes is eventual blindness. Early detection of these abnormal changes to your eyes will allow your eye care professional to initiate treatment in a timely manner so your vision can be maintained for as long as possible.
What is Hypertension (High Blood Pressure)?
Hypertension is a systemic condition in which the pressure in your blood vessels is elevated. If not properly controlled, it can lead to changes in the blood vessels in your eyes such as narrowing of the blood vessels, abnormal crossing of the blood vessels, bursting and/or leaking of blood vessels, and formation of clots in the blood vessels. These are just some of the numerous problems that can occur as a result of uncontrolled high blood pressure.
Controlling you blood pressure via proper diet, exercise, and medication, having yearly comprehensive and dilated eye examinations, and having photographs taken of the back part of your eyes are the best ways to minimize your risk of the serious and sight threatening effects of high blood pressure. Similar to diabetes, the unfortunate reality of such effects on the eyes is eventual blindness. More importantly, high blood pressure may lead to death, which is why it is called the "silent killer." Early detection of these abnormal changes to your eyes will allow your eye care professional to initiate treatment in a timely manner so your vision can be maintained for as long as possible.
Glaucoma - What is it?
An ocular condition in which the pressure in your eyes (intraocular pressure) is elevated.If not properly controlled, it can lead to damages to the tissues in the back part of your eyes. The end result of glaucoma is eventual peripheral (side) vision loss. Glaucoma begins by attacking peripheral vision, typically causing objects to appear less clearly. At first, it is possible to compensate by squinting or turning the head to focus better. But be careful. These changes may seem minor, but glaucoma can accelerate quickly; causing eyesight to rapidly and irreversibly deteriorate.
Like many diseases, some factors can increase the risk of developing glaucoma, such as age, race or genetics. Glaucoma usually affects one in 200 people by age 50, but as many as one in 10 people by age 80. The risk of developing glaucoma is much higher among African Americans: four to five times higher. In fact, glaucoma is the leading cause of blindness in African Americans. Not only do African Americans usually develop glaucoma 10 years earlier than Caucasians, they are also six to 15 times more likely to be blinded by the disease.
What's really alarming is that nearly 20 percent of adults have never been to an eye doctor, and more than 60 percent of respondents thought that glaucoma was preventable, according to the American Optometric Association's (AOA) American Eye-QTM survey. Glaucoma cannot be prevented, but if diagnosed and treated early, it can be controlled. This reinforces what the National Optometric Association and the AOA already recommend: adults need regular, comprehensive eye exams. Fortunately, Medicare covers annual glaucoma screenings for people considered at heightened risk of developing glaucoma, such as individuals with diabetes, those with a family history of glaucoma, African Americans age 50 and older and Hispanic Americans age 65 and older.
Glaucoma - How can you protect yourself?
Being compliant with your eye medications, having your eye pressure measured at your yearly comprehensive and dilated eye examinations, and having photographs taken of the back of your eyes are the best ways to minimize your risk of the serious and sight threatening effects of glaucoma. The scary thing about glaucoma is that the patients will not have any signs or symptoms which will tell them that they may have this condition which is why glaucoma is called the "silent blinder". Early detection of these abnormal changes to your eyes will allow your eye care professional to initiate treatment in a timely manner so your vision can be maintained for as long as possible.
What is Age-Related Macular Degeneration (ARMD)?
An ocular condition in which the macula (the part of your eyes that allow you to see 20/20) is degenerating. The results are distorted central vision, reduction in vision, and eventual loss of vision. One of the main causes of ARMD is exposure to UV light.
How can you minimize your risk of ARMD?
Wearing UV protective eyewear every time you are outside, eating plenty of green leafy vegetables, not smoking, having yearly comprehensive and dilated eye examinations, and having photographs taken of the back of your eyes are the best ways to minimize your risk of the serious and sight threatening effects of ARMD. Early detection of these abnormal changes to your eyes will allow your eye care professional to initiate treatment in a timely manner so your vision can be maintained for as long as possible.
What is a Cataract?
A cataract is an ocular condition in which the lenses inside the anterior part of your eyes become cloudy and harden. The results are reduced vision and glare and haloes, which are more noticeable at night, making night driving extremely dangerous. One of the main causes of cataract is exposure to UV light.
How can you minimize your risk of cataracts?
Wearing UV protective eyewear every time you are outside and having yearly comprehensive and dilated eye examinations are the best ways to minimize your risk of the effects from cataract. Early detection of these abnormal changes to your eyes will allow your eye care professional to initiate treatment in a timely manner so your vision can be maintained for as long as possible.
What is Retinal Detachment?
An ocular condition in which the retina (the tissue inside your eyes that processes the signals so that you can see) detaches from the eye. In most instances, this is a result of eye injury/trauma and/or head trauma (for examples: getting hit in the head or being in a car accident). Symptoms indicating possible retinal detachment include: an increase in floaters and/or flashing lights and/or the appearance of a persistent curtain or shadow anywhere in the field of vision. If such symptoms develop, then you need to seek immediate care from an eye care professional or go to the nearest emergency room.
What is Dry Eye Syndrome?
An ocular condition in which the eyes feel very dry and scratchy, and there may be a burning sensation. Patients may notice blurring of vision for brief periods, and blinking the eyes helps clear up the vision because blinking resurfaces the tear film over the eyes. Some patients may also have excess tears flowing out of the eyes at times because the eyes are so dry that they send a reflex signal to the brain to produce more tears, but the dryness is not alleviated.
Treatment and Management of Dry Eye:
Although there is no cure for this chronic condition, there are ways to manage the condition so that symptoms may be relieved. I use a three-step approach to the management of Dry Eyes Syndrome. The first is usage of artificial tears throughout the day. The second is punctal plugs to plug up part of the eyes' tear drainage system so that more of the tears will remain on the eyes to keep them moist for a longer period of time. The third is to prescribe a specially designed medicated eye drop that can help stimulate the tear gland to produce more tears.
What is Computer Vision Syndrome?
Computer Vision Syndrome is an ocular condition that results in eyestrain, eye fatigue, dry eyes, light sensitivity, blurred vision, headaches, and other symptoms. These symptoms are a result of the eyes and brain reacting differently to characters on the screen than they do to printed characters. These computer characters (pixels) are brightest at the center and diminish in intensity toward their edges. This makes it very difficult for your eyes to maintain focus and remain fixed onto these images. As a result, the eyes drift out to a point called the "resting point of accommodation" or RP A. The eyes involuntarily move to the RP A and then strain to regain focus on the screen and this continuous flexing of the eyes' focusing muscles result in symptoms after long hours at the computer.
Treatment for Computer Vision Syndrome:
An occupational pair of glasses can be specially designed for computer use. This computer glass will help relieve symptoms resulting from Computer Vision Syndrome.
