Detached retina. Ophthalmoscope view of patient's eye with a detached retina. The retina has peeled away from it's choroid layer (seen at upper image) & formed a gas bubble. At lower centre, red blood vessels are seen emerging from the yellow optic disc. This is also where nerves enter the eye. To the left of the optic disc the dark macula is seen, where the largest concentration of light sensitive cells occur. Retinal detachment usually results from a tear in the retina, brought about by an injury or disease. This painless condition results in a "black drape" falling across the patient's vision. Surgical treatment is usually required to prevent loss of vision.
