Valsalva retinopathy induced by vigorous nightclub dancing

A 28-year-old man with no past ophthalmic history presented with sudden loss of left central vision after dancing vigorously at a night club. On examination, visual acuity in the left eye was 6/60. Fundoscopy revealed a well circumscribed, dense preretinal haemorrhage obscuring his left fovea (Figure A). Optical coherence tomography confirmed the haemorrhage to be located just under the internal limiting membrane (Figure B). Conservative management was applied, and the patient’s vision returned to 6/6 after 3 months.
