[Hyperphosphatemia: an extremely rare cause of angioid streaks]

Angioid streaks are rare lesions of the fundus. They correspond to cracks in the Bruch membrane, which risk choroid neovessel emergence over time. We present the case of a 52-year-old diabetic patient who consulted for a macular syndrome of the left eye. The clinical examination revealed diffuse, bilateral nerve fibers with myelin, but particularly bilateral angioid streaks, complicated on the left by a juxtamacular choroid neovessel. The etiologic assessment revealed idiopathic hyperphosphatemia. We use this observation to discuss the originality of the case, the pathogenic assumption of its etiology, emphasizing the therapeutic difficulties.
