![]() ![]() Most people with RP experience progressive vision loss to near-blindness. The signs and symptoms of retinitis pigmentosa usually arise in childhood, with sensitivity to bright light or poor low light vision. The retina is the innermost layer in the eye that is responsible for the visual processing that turns light energy from photons into three-dimensional images. This inherited disease causes mutations in any of 50 genes responsible for creating proteins that enable the photoreceptor cells of the retina to work. Retinitis pigmentosa (RP): Considered a rare disease, RP is thought to affect around one in 4,000 people in the U.S.Macular edema: A build-up of fluids in the retinal tissue that causes the macula to swell.Left untreated, diabetic retinopathy can lead to blindness. The retina translates an optical image into neural impulses starting with the patterned excitation of the colour-sensitive pigments of its rods and cones, the. Diabetic retinopathy: A deterioration of the retinal tissue due to excessive glucose (sugar) levels in the blood.The vitreous naturally shrinks a bit with age, but sometimes the shrinking vitreous sticks to the retina and pulls it away from the back of the eye This can occur due to trauma (for example, a blow to the head) or due to a malfunction of the normal shrinking process of the fluid (the vitreous) that occupies the inside of the eye. Detached or torn retina: A condition that results from the retinal tissue pulling away from the back of the eyeball.Central serous retinopathy is a relatively common condition in which the central retina develops a cyst and central vision becomes distorted.Retinoblastoma may be curable, depending on whether or not the cancer has spread beyond the eyeball. Retinoblastoma occurs in children and results from an inherited gene mutation that causes retinal cells to multiply too quickly. Cancers: Cancerous (malignant) tumors of the retina are rare but include diseases like retinoblastoma.Wet AMD is rarer and occurs when new blood vessels grow abnormally in the retina, leak fluids, and cause scarring of the macula. ![]() Dry AMD is the more common type and occurs when the tissue layer of the macula becomes thinner with age. Age-related macular degeneration (AMD): One of the most common types of retinal disease, AMD causes progressive central vision loss. ![]()
