Low vision: the forgotten treatment

Low vision is subnormal visual acuity or abnormal visual field resulting from a disorder in the visual system that cannot be corrected with ordinary eye glasses or by medical or surgical intervention. The major causes for low vision are macular degeneration, diabetic retinopathy, glaucoma, and cataracts. Low vision devices are often helpful for all of these causes. A low vision comprehensive visual rehabilitation examination usually includes initial interviews with patients and their families, with an emphasis on the patients' goals and realistic expectations of what they want to achieve.
