SIGNIFICANCE: This case highlights ocular ischemia after hemodialysis resulting in permanent vision loss. Fifteen percent of the U.S. population suffers from chronic kidney disease. Eye care providers should recommend risk factor modifications to their patients with end-stage renal disease before hemodialysis is started to prevent loss of vision.
PURPOSE: The purpose of this study was to demonstrate a case of concurrent nonarteritic anterior ischemic optic neuropathy and central retinal artery occlusion in the setting of hemodialysis initiation.
CASE REPORT: A 68-year-old Irish man with end-stage renal disease undergoing dialysis presented, complaining of 3 weeks of progressive vision loss in his left eye. His medical history is complex and includes extensive cardiac disease, bilateral carotid stenosis, and peripheral vascular disease. His surgical history includes a right carotid endarterectomy, bilateral lower extremity amputations, and an aortic valve replacement. Clinical examination revealed light perception vision with an afferent pupillary defect in the left eye and count finger peripheral vision only in the superior temporal quadrant of his vision. The dilated fundus examination showed significant pallid disc edema and focal areas of retina whitening with attenuated peripapillary vasculature in the left eye. This edema was confirmed by optical coherence tomography and supported optic nerve and retinal infarction. A temporal artery biopsy confirmed no evidence of arteritis.
CONCLUSIONS: Hemodynamic disruption during dialysis in patients with end-stage renal disease and overlying anemia can result in optic nerve and retinal infarction. Patients who are predisposed to nonarteritic anterior ischemic optic neuropathy or central retinal artery occlusion should be educated on this before starting dialysis to ensure careful blood pressure monitoring.
