Low vision is a general medical term used to describe impaired vision in both eyes that cannot be corrected to normal with medical treatment, surgery, or eyeglasses. The term low vision does not refer to any particular disease, it refers to the visual impairment itself, which can be caused by any of a wide variety of eye, optic nerve, and brain disorders. The leading causes of low vision are age-related eye diseases such as macular degeneration, glaucoma, and diabetic retinopathy. Although these diseases can be treated to slow or prevent further vision loss, any damage already done to the nerves in the eye or vision part of the brain cannot be undone, so in most cases the low vision is permanent.
The Lions Low Vision Rehabilitation Network (Lions LOVRNET) is a model for a new community based healthcare program that will address the current shortage and distribution of low vision rehabilitation services and can expand to keep pace with the growth in demand as our population ages.
