What Are the Symptoms of a Damaged Retina?
The retina is the innermost layer in the back of the eye and is the portion of the eye that receives light. The function of the retina is to receive light that passes through the lens and converts the light into neural signals, which are transmitted to the brain for visual recognition. The retina is crucial for vision. Damage to the retina is called retinopathy. Retinopathy has many causes and leads to visual impairment. Early diagnosis and treatment can help stop the progression of the disease as well as loss of vision, and aid in vision restoration.
