[Chorioretinopathy as the first symptom of acute lymphoblastic leukaemia].

Central serous chorioretinopathy (CSCR) is an ophthalmic disease characterized by a serous detachment of the macula. It is most often idiopathic and self-limiting. A 61-year-old patient presented with bilateral blurred vision and double vision. Ophthalmological examination showed bilateral CSCR, and a haematological examination led to the diagnosis of an underlying acute lymphoblastic leukaemia. Bilateral visual loss with fast onset should lead to subacute ophthalmological examination. Underlying heamatological disease must be considered in patients with atypical CSCR.
