To describe a patient with sickle cell trait who developed latent proliferative sickle cell retinopathy after mild blunt trauma.
Case Report. A 20-year-old man with unilateral Stage 3 sickle retinopathy associated with an ischaemic ridge presenting three years after the initial mild blunt ocular trauma.
Fundus examination of the left eye showed an ischaemic ridge delineating avascular from vascular retina. Fluorescein angiography of the left eye showed an avascular peripheral retina and multiple sea fan neovascularization. Blood studies showed him to be Hb AS.
In our patient the proliferative changes were the result of his initial mild trauma associated with an increase in the intraocular pressure. The latent development of the sea-fan neovascularization associated with an ischaemic ridge is unusual. Advice about potential complications to patients with Hb AS after ocular trauma is advocated.
描述一名镰状细胞性状患者在轻度钝性创伤后发生潜在增殖性镰状细胞视网膜病变的情况。
病例报告。一名20岁男性，在最初的轻度钝性眼外伤三年后出现单侧3期镰状视网膜病变，伴有缺血嵴。
左眼眼底检查显示一条缺血嵴，将无血管的视网膜与有血管的视网膜区分开来。左眼荧光素血管造影显示周边无血管视网膜和多处海扇状新生血管形成。血液检查显示他为血红蛋白AS型。
在我们的患者中，增殖性改变是其最初轻度创伤与眼内压升高相关的结果。与缺血嵴相关的海扇状新生血管的潜在发展并不常见。提倡向血红蛋白AS型眼外伤患者告知潜在并发症。
