 Retinal disease can steal your eyesight, but it doesn't have to. Patients who seek care from a retina specialist in a timely manner have the best chance of preventing vision loss due to age-related macular degeneration or diabetic retinopathy. AMD symptoms to look out for are distortion or warping of straight lines, as well as blurred or loss of central vision. Patients with diabetic retinopathy should seek treatment if they notice the appearance of spots or floaters or blurred and distorted vision.
