A 42-year-old Caucasian male presented with a 1-week history of blurred vision in his right eye following a flu-like illness. He had been treated for an upper-respiratory-tract infection and 2 days later developed pain and blurring of vision in his right eye. He had no significant past medical, ophthalmic or family history.

A differential diagnosis of central serous retinopathy (CSR), Harada syndrome, unilateral acute idiopathic maculopathy, idiopathic choroidal neovasculariation and acute posterior multifocal placoid pigment epitheliopathy (APMPPE) was made.

Discuss the OCT and FFA findings (figs 1–3). 2. What is your diagnosis? 3. How would you manage this …
