The authors describe a patient who presented with bilateral disc oedema and left eye visual loss. The patient was evaluated for intracranial space occupying lesion, however, a CT and cerebrospinal tap was normal. No definitive diagnosis could be established and patient developed left eye optic atrophy which was thought to be post papilloedema atrophy. Six months later, the patient had similar visual loss in right eye and he was diagnosed as anterior ischemic optic atrophy (AION) by the ophthalmologist. The inferior altitudinal visual field loss, delayed visual evoked response and clinical picture supported the diagnosis. The patient was diagnosed with hypertension and type 2 diabetes and managed accordingly. All the symptoms, clinical findings, investigations supported the diagnosis of AION which occurred in left eye followed by right eye 6 months later. Appropriate treatment was started and patient regained vision in right eye.
作者描述了一名出现双侧视盘水肿和左眼视力丧失的患者。该患者接受了颅内占位性病变评估，然而，CT和脑脊液检查均正常。未能明确诊断，患者出现了左眼视神经萎缩，被认为是视乳头水肿后萎缩。六个月后，患者右眼出现类似的视力丧失，眼科医生将其诊断为前部缺血性视神经病变（AION）。下方视野缺损、视觉诱发电位延迟以及临床表现支持这一诊断。该患者被诊断患有高血压和2型糖尿病，并相应地进行了治疗。所有症状、临床发现和检查均支持AION的诊断，该疾病先发生于左眼，6个月后累及右眼。开始了适当的治疗，患者右眼恢复了视力。
