Paraneoplastic retinopathy is a rare cause of painless vision loss, associated with an underlying (and often occult) systemic malignancy. Ocular examination findings are subtle, and the diagnosis is often made on the basis of electrophysiology findings. This report describes the case of a 48-year-old Caucasian man with paraneoplastic retinopathy presenting as visual disturbance, central scotomata and abnormal electrophysiology. He was subsequently diagnosed with papillary thyroid malignancy.
