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.
我们报告一例与新生血管性青光眼(NVG)相关的非动脉炎性前部缺血性视神经病变(NAION)。一名3个月前接受白内障手术的63岁男性,右眼突然视力丧失。眼部检查发现相对传入性瞳孔障碍、眼压(IOP)为27 mmHg以及360°新生血管形成。眼底检查发现苍白、肿胀的视盘伴有糖尿病性视网膜病变。诊断为与NVG相关的NAION。NVG导致视神经灌注压降低,同时合并糖尿病性视网膜病变的缺血过程,从而导致NAION。
