A report of choroidal neovascularisation (CNV) associated with radiation retinopathy. A 43-year-old Caucasian man presented with a 4-week history of sudden loss of central vision in the left eye, 8.5 years following radical radiotherapy for left tempero-parietal anaplastic astrocytoma. His visual acuity was 6/6 in the right eye and 6/60 in the left eye. Ophthalmoscopy of the left eye showed central macular pigmented area surrounded by subretinal fluid, haemorrhage and exudates. Fundus fluorescein angiography revealed left subfoveal CNV with surrounding macular oedema and peripheral retinal ischaemia. Radiation retinopathy associated CNV is a late ocular complication of cerebral radiotherapy. It should be investigated as a possible aetiology of severe visual loss in long-term survivors of cerebral tumours who have previously received radiotherapy.
一份关于放射性视网膜病变相关脉络膜新生血管形成（CNV）的报告。一名43岁的白种男性，在接受左侧颞顶间变性星形细胞瘤根治性放疗8.5年后，出现左眼中心视力突然丧失4周的症状。他的右眼视力为6/6，左眼视力为6/60。左眼检眼镜检查显示中心黄斑色素沉着区被视网膜下液、出血和渗出物包围。眼底荧光血管造影显示左黄斑下CNV伴周围黄斑水肿和周边视网膜缺血。放射性视网膜病变相关的CNV是脑部放疗的一种晚期眼部并发症。对于先前接受过放疗的脑肿瘤长期幸存者中严重视力丧失的可能病因，应将其作为一种可能病因进行调查。
