Cancer-associated retinopathy (CAR) is a rare form of retinal degeneration that occurs in association with certain forms of cancer. CAR patients typically possess high titers of autoantibodies against a specific photoreceptor protein--the 23 kD retinal CAR antigen. The mechanisms involved in the vision loss experienced by CAR patients are not understood, but serologic studies indicate the process could include a series of autoimmune reactions directed at specific components of the retina… CONTINUE READING
