Retinopathy An optic pathology in which the retina, the inner membrane of the eyeball containing the photoreceptors, is affected. The most common cause of retinopathy is vascular disorders, leading to bleeding👆🏻 As a result, a person has a narrowed field of vision, blurred vision, and photopsia (the appearance of bright "dots" in the eyes). The commonest cause of retinopathy is diabetes, as it affects blood vessels. Their walls lose their elasticity and vessels become brittle, so they are easily injured.
