Causes of Low Vision
Low vision can be caused by eye diseases, such as macular degeneration, glaucoma, diabetic retinopathy and retinitis pigmentosa. It can also be caused by eye injuries. These conditions can occur at any age but are more common in older people. However, normal aging of the eye does not lead to low vision.
Low vision may also result from cancer of the eye, albinism or a brain injury. If you have these disorders or are at risk for them, you are also at greater risk for low vision.
Regular medical eye exams by an ophthalmologist are important to diagnose eye diseases, treat those conditions that can be helped, and start the process of vision rehabilitation for people with low vision.
