It is generally accepted that dialysis may lower plasma osmolality at a faster rate than changes in ocular osmolality. This osmotic difference causes water to migrate from the plasma into the aqueous humor, increasing intraocular pressure. Certain authors have described IOP increase in patients with narrow angles.
Here we report a neovascular glaucoma patient who experienced a substantial increase in IOP associated with severe eye pain and blurred vision during sessions of dialysis. The patient had been refractory to several antiglaucoma drugs and improved after intravenous administration of 20 % hyperosmotic glucose solution with dialysis and pan-retinal photocoagulation.
