A 78-year-old man with familial amyloidotic polyneuropathy type I (Met30), presented with rubeotic glaucoma 9 months following an uncomplicated vitrectomy for vitreous amyloidosis. There was retinal neovascularization and extensive retinal vascular closure. In the preceding 9 months, episodes of 'uveitis' and high intraocular pressure are thought to be due to amyloid protein released into the aqueous leading to trabecular meshwork obstruction and high intraocular pressures, thus compounding the ocular ischaemia created by amyloid vascular closure. The patient underwent pan-retinal photocoagulation and Molteno implant surgery. The rubeosis regressed and pressure control was gained but sight was lost.
