Macular Degeneration Evaluation & Treatment
The beginning point is always an individualized, preventative, comprehensive eye health examination. If AMD is suspected, other tests may be performed.
Amsler Grid – The Amsler Grid is an important simple tool that tests macular vision and helps detect specific types of vision loss associated with AMD. This test uses a grid chart and can be administered in the office, but also may be taken home for monitoring by the patient. We put the Amsler Grid Eye Test at the bottom of each page on this website. To take the test, open and print the 2 PDF files and follow the directions.
Visual Field Testing – Sophisticated central visual field testing can show loss of central vision sensitivity even though visual acuity may not be affected.
Nutrients – A recent study (AREDS 2) showed the effectivity of several nutrients but especially the two pigments, Zeaxanthin and Lutein. These two nutrients are present in food and can increase the pigment when eaten in large enough quantities. However, the fastest way to increase the macular pigment is through OTC Eye Vitamins available in our clinic, online or at your local drug store.
Hemianopsia Vision Loss Treatment in Dunedin, Florida
What is Hemianopsia?
Hemianopsia, also known as hemianopia is a loss of vision on one side of a persons vision (field of vision). In most cases it cuts the field of vision in half and is on either the right side or the left side but it can be on the upper side or lower side of what a person sees. There is also quadranopsia which is a loss of the quarter (25%) of the field of vision.
This loss of vision may also be a equal loss in the other eye as well such that both eyes have lost vision on the right side or left side. When tis occurs it is called a homonymous hemianopsia (HH). Many HH are caused from a stroke (CVA) but can be caused from head trauma or from neurological disease. A person suffering from a HH may have difficulty reading, seeing to safely walk through crowds or doorways without bumping into things. They may have difficulty grooming themselves. Additionally, driving privileges may be removed due to loss of vision on one side and therefore not having the minimum amount of visual field for safe driving.
What can be done in a low vision examination for this problem?
During the low vision examination we will determine what functional field of vision a person with an HH has and determine the best way to expand the field of vision. Visual field expansion is done witheyeglasses containing lenses with prism and/or vision rehabilitation such as NOVA Vision (http://www.novavision.com/). Eyeglasses with prism are prescribed and even before purchase the person with the vision loss is able to try them to see if they work. The lenses with prism appear almost normal and can be placed into any standard eyeglass frame. In many cases the field of visioncan be expanded to allow for driving again and certainly for safer ambulation. NOVA Vision is a vision rehabilitation system hat takes advantage of the brain’s ability to “rewire” itself. This ability is known as neural plasticity. Whether rehabilitation is provided with prism glasses or NOVA Vision a one hour low vision examination will provide you with the answers to hemianopsia vision loss.
Hemioanopsia is also associated or maybe called: CVA, stroke, hemianopsia, hemianopia, quadranopsia, quadranopia, prism, peli lens, Gottlieb lens, visual field awareness system, Inwave, sector prism, nova vision, vision rehabilitation.
Glaucoma Vision Loss Treatment
Treatment of open-angle glaucoma — the most common form of the disease — requires lowering the eye’s pressure by increasing the drainage of aqueous humor fluid or decreasing the production of that fluid. Medications can accomplish both of these goals. Surgery and laser treatments are directed at improving the eye’s aqueous drainage.
If not diagnosed early, open-angle glaucoma may significantly damage vision and even cause blindness. That is why it’s so important to have your eye doctor test you regularly for glaucoma. Once diagnosed, glaucoma is usually controlled with eye drops that reduce eye pressure. Glaucoma is a life-long condition and needs continual follow-up with your eye doctor.

Binocular Vision Treatment
Depending on the cause, the treatments for binocular vision vary, but they include:
- wearing glasses, sometimes with prism
- eye exercises
- wearing an opaque contact lens
- botulinum toxin (Botox) injections into the eye muscles, causing them to remain relaxed
- wearing an eye patch
- surgery on the muscles of the eye to correct their positioning
Pediatric Specialty Eye Care
The causes of reading and learning problems in children are numerous. One source of these problems is overlooked a majority of the time and is related to our eyes. This problem is not regarding eyesight as you may think, but related to vision. Let me explain the difference between eyesight and vision.
Eyesight is how clearly a person is able to see where vision is that, plus how the two eyes work together as a team and function so the visual information is processed properly. The eyes may appear to be aligned and working properly together but, in actuality, they are not.
Our eyes are designed to work together for proper visual efficiency. This allows for accurate tracking, alignment, and focusing. A child with a vision problem may think they see everything properly but, as is often stated, they don’t know what they don’t know.
A child struggling with reading may exhibit clumsiness in the classroom or playground, excessive squinting or closing one eye, excessive blinking or unusual postural positions when in the classroom or reading. A parent may notice variability in sports performance. The child may be one that can remember long passages heard in a movie or TV, but has difficulty remembering what they have read.
Harmful Blue Light
Another factor that can affect how your child sees is exposure to harmful blue light.
Blue light, part of a light spectrum that is visible to the human eye, provides basic illumination. But the effects of blue light on vision can be wide ranging and potentially damaging to young eyes. This is because their maturing eyes haven’t yet developed the protective pigments to help filter out some of the harmful blue light that comes from artifactual lighting and handheld devices.
Your eyecare professional can provide you with more information on how to protect your child’s eyes from harmful blue light.
