Cancer-associated retinopathy – A rare differential diagnosis for tubular vision

Carcinoma-associated retinopathy is a rare autoimmune retinopathy which involves the presence of auto-antibodies against the retinal photoreceptors. Here, we present the case report of a 62 years old female with significantly constricted visual fields which could not be attributed to any ophthalmic cause. History of breast cancer helped us correlate and confirm the cause. The patient was kept under close observation in view of good vision and stable visual field at the time of presentation. Cancer-associated retinopathy should be ruled out in patients presenting with constriction of visual fields with history of systemic cancer. Also, workup for possible malignancy should be done in patients with unexplained visual field loss/constriction.
