title: Autoimmune retinopathy.
abstract: Autoimmune retinopathy encompasses a spectrum of rare autoimmune diseases that primarily affect retinal photoreceptor function, and include cancer-associated retinopathy (CAR), melanoma-associated retinopathy (MAR) and presumed non-paraneoplastic autoimmune retinopathy (npAIR). Autoimmune retinopathy typically presents in the fifth and sixth decades with rapidly progressive, bilateral, painless visual deterioration but an unremarkable fundus examination. CAR, MAR and npAIR have an overlapping clinical phenotype, and extensive investigation is required to exclude other causes of retinopathy, and to identify any occult malignancy, before a presumptive diagnosis can be made. Delayed diagnosis, and treatment initiation relatively late in the disease course, may contribute to the poor visual prognosis. Various treatments have been attempted, including systemic immunosuppression with steroid and steroid-sparing agents, intravenous immunoglobulin, and plasmapheresis, but these lack an evidence base. A variety of antiretinal antibodies have been identified in patients with autoimmune retinopathy, including antibodies to recoverin, α-enolase and transducin-α, but seronegative disease is also common. Clinical access to specialised serological investigation is very limited internationally, and this exacerbates the management challenge presented by patients with suspected autoimmune retinopathy. Several decades of experimental research have resulted in very considerable advances in our understanding of the pathophysiological mechanisms that may underlie autoimmune retinopathy. However, the precise triggers which result in loss of ocular immune privilege and sudden autoimmune attack on retinal cells have yet to be elucidated. This review summarizes the classification, investigation and management of autoimmune retinopathy, and considers the evolving concepts about its immunological aetiology.
