Low vision is a general term that refers to a partial loss of vision that cannot be adequately corrected with eyeglasses, contact lenses, medications or surgery. Common causes of low vision include macular degeneration, diabetic retinopathy, inherited retinal degenerative diseases, glaucoma and optic nerve atrophy.

Low vision therapy typically includes an evaluation of the patient’s visual abilities, prescription of low vision devices and training in their use. The goal is to maximize the use of the patient’s available vision for reading, writing, hobbies and work-related tasks such as working at a computer.
