Retinal disease refers to a group of conditions that affect the retina, the light-sensitive tissue at the back of the eye. Common types include age-related macular degeneration, diabetic retinopathy, and retinal detachment. These diseases can lead to vision loss or blindness if not diagnosed and treated early. Symptoms of retinal disease may include blurred vision, dark spots, or sudden changes in vision. Regular eye exams are essential for early detection and management. Treatments can vary from medications and laser therapy to surgical procedures, depending on the specific condition and its severity.
