[Case Report] Sight-threatening intraocular pressure due to an upper arm dialysis fistula
In October, 2013, a 52-year-old man presented with 1 month of left eye redness, intermittent blurred vision, and occasional diplopia. He had quiescent treated bilateral proliferative diabetic retinopathy, controlled hypertension, and dialysis-dependent diabetic nephropathy. 1 month before his left forearm arteriovenous dialysis fistula had failed and he had had surgical formation of an upper arm (brachiobasilic) fistula. On examination, visual acuity was unchanged from previous testing (6/9·5 bilaterally) but colour vision was reduced on the right.
