Q: What is “Low Vision”?
A: The term “low vision” refers to partial sight that cannot be corrected with surgery, drugs, eyeglasses, or contact lenses. The condition can range from having unsatisfactory vision to being nearly blind. The causes of low vision include eye injury, diseases such as age-related macular degeneration (AMD), and heredity. As a result of reduced visual acuity or decreased contrast sensitivity, low-vision individuals may be unable to fully distinguish colors, see contrasts, or determine spatial relationships among objects. Fortunately, there are a variety of devices and strategies available for helping people with low vision overcome vision loss and live independently.
Q: What is diabetic retinopathy?
A: Diabetic retinopathy (DR) is an eye disease that can occur at any stage and with any type of diabetes. In fact, sometimes diabetes is identified during an eye exam in a person who never suspected it. It is caused by damage to the very delicate blood vessels within the retina at the back of the eye. As DR progresses, these blood vessels may start to leak blood and fluid into the retina or other areas of the eye, and new vessels may begin to grow within the retina, which can cause vision loss, and sudden complications including internal bleeds and retinal detachment.
