Treatment Available for Macular Degeneration Low Vision in Connecticut
DANBURY, Conn., April 23, 2013 /PRNewswire-iReach/ -- Prismatic Magnifying Readers (PMRs) can often help people with macular degeneration, glaucoma, diabetic retinopathy and others with low vision who are having difficulty reading by providing extra magnification and comfort. The most common vision loss for someone with low vision is the reduced ability to read.
Dr. Randolph Kinkade, a Connecticut optometrist and founding member of the International Academy of Low Vision Specialists, has coined the new term Prismatic Magnifying Readers to describe the design and purpose behind these beneficial low vision glasses.
Prismatic Magnifying Readers, when combined with enhanced illumination, often improve reading ability. Individuals whose vision is in the range of 20/50 to 20/200 and is relatively equal in both eyes can benefit from PMRs.
"The prism enables material to be held at a closer reading distance allowing for more magnification and comfort", said Dr. Kinkade. "The prism improves binocular viewing which in turn improves the reading field of view. Words are not only larger, but more words can be seen at a time."
Holding reading material close (closer than 16") creates the magnification. The closer the reading material is held to the eyes the more the focusing magnification can be created by the glasses. For example, when reading material is held at 8" from the eyes 2X magnification is created compared to when the same material was held at 16" (a normal reading distance). When the material is held at 4" from the eyes 4X magnification is generated. Bigger is better for people with low vision.
Lens strength is usually measured in the optical term "diopters" which is different than "magnification power". The more diopters in the prescription the closer the reading material must be held to the eyes.
"The prism is designed to reduce binocular eye fatigue and reading stress", said Dr. Kinkade. "The closer the book is held to the eyes, the more the eyes must turn in for binocular viewing. Without prism, there is a limit to how much the eyes can naturally and comfortably turn in."
There are also limits to the amount of prism that can be beneficial in a prescription. Twelve units of prism in each eye is often the practical limit. At a 4" viewing distance patients may be better off reading with one eye; the best eye. At this point the prescription is changed from PMRs to monocular microscopic glasses (very high power for one eye only).

About Macular Degeneration
Macular degeneration is usually an age-related eye disease that can result in considerable vision loss. It occurs when the macula, or center part of the retina providing 20/20 vision, begins to breakdown.
The macula is an extremely important part of the retina used for seeing. It allows us to focus and carry out many vision related duties like reading, writing, driving and crafts. The macula is essential for crisp detail vision.
Dry macular degeneration is considered the most common (80-90%) and consists of yellow deposits (drusen) developing in the macula. In dry macular degeneration, blind spots develop within the line of vision. The decrease in vision is usually gradual and takes many years to develop. There is not effective treatment for this form of the disease.
Wet macular degeneration is more prone to rapid and severe vision loss if not treated. In this condition blood vessels develop and leak fluid behind the macula. Current treatment involves a series of injections to stop the vessels from developing.
