Common Causes of Low Vision

Macular Degeneration

This condition refers to a breakdown of the macula, which is the area of your retina responsible for clear central vision. A blind spot generally develops in the center of your field of vision, causing trouble with reading and focusing. There are two types of macular degeneration, and together they are the leading cause of blindness in people above 50 years old.

Diabetic Retinopathy

Diabetes, especially when uncontrolled, can cause retinal blood vessels to leak. Over time, this disturbs vision and can damage the retina, causing Low Vision. Laser surgeries and other medical treatments can slow the progression of diabetic retinopathy, but proper regulation of blood sugar levels is the most effective way to treat this condition.


As pressure of inner eye fluid builds up, it can damage the optic nerve. Glaucoma is characterized by a problem with drainage or flow of this fluid and an improper level of internal pressure in the eye. Usually, there are no early signs of glaucoma until side and/or night vision is affected. When diagnosed early, drugs (and sometimes surgery) are highly effective at treating glaucoma and preventing the development of Low Vision.


A cataract refers to when the normally clear lens of your eye becomes cloudy. Due to the opaque cloudy lens, light does not reach the retina, which results in Low Vision. Aging, UV rays from the, genetics, disease and eye injury can all contribute to your chances of developing cataracts. Surgery to remove the cataract is highly successful. Typically, an intraocular lens implant is inserted and vision returns to normal. However, when a patient is not a candidate for cataract surgery, Low Vision Assistance is often needed to help maximize eyesight.

Retinitis Pigmentosa

This disease is inherited and typically appears first in childhood or adolescence with the symptom of night-blindness. Retinitis pigmentosa gradually destroys night vision and diminishes peripheral vision.
