Anterior ischemic optic neuropathy and dialysis: Effect of hypotension
A 30-year-old female presented with sudden loss of vision OS. Past medical history was significant for renal failure secondary to glomerulonephritis and she was on dialysis while waiting for renal transplantation. She too was experiencing low blood pressure during dialysis. She was found to have a left posterior ION with a superior altitudinal defect on Goldmann visual field testing. She represented 3 months later with loss of residual inferior field OS. Six months after her initial presentation with visual loss, she suffered a right AION affecting the inferior part of the annulus and causing a right superior field defect. She also developed mild ocular ischemic syndrome with a right cataract for which she underwent a right phacoemulsifcation and intraocular lens implantation (IOL). She has maintained vision of 6/9 OD as she still has her inferior field and is under 6 monthly review.
