A 46-year-old woman with no known past medical history presented with sudden painless visual impairment in the left eye. Ocular examination showed a swollen and hyperaemic left optic disc with a small and crowded right optic disc. Intraocular pressures were moderately elevated. Investigations for underlying ischaemic and inflammatory markers were normal. A diagnosis of left non-arteritic anterior ischaemic optic neuropathy (NAAION) was made, with associated ocular hypertension. On follow-up, NAAION resolved with anti-glaucoma medication and repeat fundus examination confirmed the presence of an underlying hypoplastic disc. The coexistence of optic disc hypoplasia and elevated intraocular pressure may further augment the risk of developing NAAION.
一名46岁无已知既往病史的女性因左眼突然无痛性视力障碍就诊。眼部检查显示左眼视盘肿胀、充血，右眼视盘小且拥挤。眼压中度升高。对潜在缺血和炎症标志物的检查结果正常。诊断为左眼非动脉炎性前部缺血性视神经病变（NAAION），伴有继发性高眼压。随访时，NAAION经抗青光眼药物治疗后缓解，重复眼底检查证实存在潜在的视盘发育不全。视盘发育不全与眼压升高并存可能会进一步增加发生NAAION的风险。
