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.
