We prospectively evaluated 22 consecutive patients (24 eyes) suffering from non-arteritic anterior ischaemic optic neuropathy (NAION) at a tertiary care centre in Northern India. The mean age was 51.7 years. Visual loss on awakening was noticed only in three (12.5%) eyes. Six (27.3%) patients had headache while three (9.7%) patients had retro-orbital pain at the onset of visual loss. Peripapillary haemorrhages were seen in two (8.3%) eyes. At follow up, only one eye showed improvement in visual acuity. The results of our study suggest that NAION may not always present with the classic clinical picture. Accordingly, a high index of suspicion remains the key to correct diagnosis.
我们在印度北部的一家三级医疗中心对22例连续的非动脉炎性前部缺血性视神经病变（NAION）患者（24只眼）进行了前瞻性评估。平均年龄为51.7岁。仅3只眼（12.5%）在醒来时出现视力丧失。6例（27.3%）患者有头痛，而3例（9.7%）患者在视力丧失发作时有眶后疼痛。2只眼（8.3%）可见视乳头周围出血。随访时，只有1只眼视力有所改善。我们的研究结果表明，NAION可能并不总是表现出典型的临床症状。因此，高度的怀疑指数仍然是正确诊断的关键。
