Non-progressive CRMP-5-Associated Perifoveal Retinopathy in a Breast Cancer Patient: A Rare Paraneoplastic Phenomenon.

Paraneoplastic retinopathy (PR) is a rare autoimmune condition typically associated with progressive visual loss and is often linked to anti-recoverin antibodies. Paraneoplastic optic neuropathy (PON) is classically associated with collapsin response-mediator protein (CRMP-5). We present a unique case of non-progressive CRMP-5-associated perifoveal retinitis in a 79-year-old female with a history of breast carcinoma, who has maintained a stable visual acuity over an extended follow-up period of three years.
