Renewed Vision for Macular Degeneration

In Connecticut, Spectacle Miniature Telescopes (SMTs) are emerging as a viable option for many patients with low vision (vision-limiting conditions) such as macular degeneration. These mini-telescopes are fabricated into glasses and allow the patient's prescription to be incorporated inside telescope as well as into the eyeglass lens. The telescopes can be prescribed for one or both eyes depending on the level of vision and the patient's goals.

About Macular Degeneration

Age related macular degeneration (AMD) is the leading cause of vision loss in those over 60. By definition, macular degeneration affects only the macular portion of the retina. The retina, like film in a camera, is the photosensitive layer of the eye and is tissue paper thin. The macular portion of the retina is the part or the retina we use for sharp, clear detail center vision. The rest of the retina, the peripheral or side vision retina, is used for walking and detecting motion.

Dry (atrophic) macular degeneration is when the macular photosensitive cells breakdown. Causes can be from aging, poor nutrition, excessive sunlight exposure, years of smoking, genetics and other causes we may not know about yet. There is simply no medical treatment for dry AMD.

Wet (exudative) macular degeneration is caused by leakage of fluid from blood vessels behind the macula. Treatment involves a serious of periodic injections into the eye.  The treatment is provided to prevent the condition from getting worse.  In some cases it can improve vision. 

Currently, retinal cells cannot be regrown, replaced, moved or transplanted.
