One month after blunt trauma, fundoscopy of a 35-year-old shows a yellowish-white crescentic streak concentric with the optic disc, temporal to the disc, with associated subretinal haemorrhage. The most likely diagnosis is:

• A Choroidal rupture ✓
• B Angioid streaks
• C Lattice degeneration
• D Retinal pigment epithelium tear

Explanation

Traumatic choroidal rupture appears as a single or multiple crescent-shaped breaks, classically concentric to and temporal or nasal to the optic disc, caused by mechanical splitting of Bruch membrane, choriocapillaris and RPE during globe compression. Angioid streaks look similar but are bilateral, crack-like, radiating around the disc, and unrelated to trauma, which is the fact that excludes that distractor.
