Recovery of Outer Retinal Laminations on Optical Coherence Tomography After Treatment of Cancer Associated Retinopathy

Abstract

a b s t r a c tPurpose: To report novel optical coherence tomography findings in a case of anti-a-enolase cancer associated retinopathy. Observations: An elderly female presented with bilateral decreased vision and a recent diagnosis of ovarian carcinoma. Optical coherence tomography demonstrated bilateral loss of outer retinal structures and macular edema. Serum testing found antibodies against a-enolase and 82e84 kDa proteins. Outer retinal structures showed recovery, macular edema resolved and repeat anti-retinal antibody testing became negative following cancer therapy and topical difluprednate treatment. Conclusions and importance: Cancer associated retinopathy is a paraneoplastic disease that results in damage to retinal structures through an autoimmune response. The damage is generally considered to be irreversible; however, in rare cases, such as observed here, retinal structures may demonstrate recovery after treatment.
