A Case of Partial Occlusion of Branch Retinal Artery in Patient with Mitral Valve Prolapse

Authors have experienced a case of retinal occlusion in patient with mitral valve prolapse. The patient was 10-year-old male who had visited our hospital due to the sudden onset of painless diminished vision and visual field defect of right eye since 2 days ago. The funduscopic finding of right eye showed typical appearance of retinal arterial occlusion with ischemic retinal whitening which app3ared as opacification. And, we also found mitral valve prolapse in this patient. One of the recently reported complications of mitral valve prolapse is thromboemboli resulting in cerebral ischemic events and visual complications. Such emboli can explain some cases of branch and central retinal arterial occlusion.
