Abstract:
We report a case of non-arteritic anterior ischaemic optic neuropathy (NAION) associated with neovascular glaucoma (NVG). A 63-year-old man who had undergone cataract surgery 3 months previously presented with sudden visual loss in his right eye. Ocular examination revealed a relative afferent pupillary defect, intraocular pressure (IOP) of 27 mm Hg, and 360° neovascularisation. Fundus examination revealed a pale and swollen optic disc with diabetic retinopathy. NAION associated with NVG was diagnosed. NVG, leading to reduced optic nerve perfusion pressure, concurrent with ischaemic processes of diabetic retinopathy, resulted in NAION.
