Increased Intraocular Pressure During Hemodialysis: Ocular Dialysis Disequilibrium.

A man in his early 70s presented with a 1-month history of headache, left-sided photophobia, periorbital pain, and redness occurring during hemodialysis. He had a history of ESKD secondary to diabetic nephropathy and of proliferative diabetic retinopathy. We observed elevated intraocular pressure during dialysis. A diagnosis of neovascular glaucoma with a compromised iridocorneal angle was made. Medical management of glaucoma and modifications to the hemodialysis regimen were initiated but were insufficient. The resolution of symptoms required surgical management, including cataract extraction with intraocular lens placement, pars plana vitrectomy, and peripheral retina endolaser, and placement of an Ahmed glaucoma drainage valve. This case illustrates the importance of attention to intraocular pressure and risk factors for glaucoma in patients treated with hemodialysis. Clinicians caring for patients treated by hemodialysis should consider hemodialysis-related elevation in intraocular pressure as a possible etiology for headache, visual changes, or ocular symptoms during dialysis and should pursue ophthalmic evaluation.
