A 32-year-old man presents with blurred vision in the right eye for two weeks. He has recently been taking oral corticosteroids for an acute asthma exacerbation. Fundoscopy shows a well-circumscribed serous elevation of the sensory retina at the posterior pole without haemorrhage or exudate. The most likely diagnosis is:

• A Central serous chorioretinopathy ✓
• B Cystoid macular oedema
• C Optic disc pit maculopathy
• D Choroidal neovascular membrane

Explanation

Central serous chorioretinopathy classically affects young to middle-aged men and is strongly associated with systemic or inhaled corticosteroid use, pregnancy and type A personality. It produces a circumscribed serous detachment of the neurosensory retina at the macula due to focal retinal pigment epithelial decompensation. Most cases resolve spontaneously within three to six months. Choroidal neovascularisation would show haemorrhage or lipid exudate, which are absent here.
