[Bilateral effusion syndrome induced by chlorthalidon].

Uveal effusion can lead to anterior swelling of the choroid up to angle-closure glaucoma. This article reports the case of a 57-year-old male patient who presented with headache, vertigo and bilaterally reduced visual acuity. The examination showed a myopic shift and angle-closure glaucoma caused by uveal effusion. The medical history revealed that 3 days before the appearance of the symptoms, treatment with chlorthalidone was added to the antihypertensive medication. After discontinuation of the chlorthalidone intake the uveal effusion and its concomitant symptoms disappeared without residues.
