Choroidal calcification in Bartter syndrome.

Abstract

Bartter syndrome is characterized by hyperplasia of the renal juxtaglomerular apparatus, hyperaldosteronism, and hypokalemic alkalosis. We report a case of Bartter syndrome associated with normal serum calcium levels and posterior choroidal calcification. Case report. A 59-year-old man with bilateral cataract and Bartter syndrome underwent a complete ophthalmic examination, including standardized echography before and after cataract surgery. Before cataract surgery, echography identified small, hyperreflective, multifocal, bilateral choroidal lesions with posterior shadowing. After surgery, these lesions appeared as yellow-white, barely elevated plaques with smooth edges and were diagnosed as choroidal calcification. Choroidal calcification may occur in patients with Bartter syndrome. This condition should be added to the differential diagnosis of posterior segment calcification.
