To report a case of sequential retinal pigment epithelium (RPE) tears following intravitreal Ranibizumab injections for neovascular age-related macular degeneration (AMD).
Retrospective, observational case.
A 75-year-old hypertensive male was diagnosed with active neovascular AMD and pre-existing RPE tear in the left eye. His presenting best-corrected visual acuity was counting finger @ 1 metre, <N36 in the right eye and 6/9, N8 in the left eye respectively. The right eye fundus had a scarred choroidal neovascular membrane (CNV) with extensive hard exudates. The left eye fundus showed active CNV, subretinal fluid and haemorrhage and a large RPE tear inferior to the fovea with rolled up margins. Following treatment with intravitreal Ranibizumab injection (Accentrix®, Alcon, 0.5 mg/0.05 ml) at monthly intervals, patient developed two extra RPE tears following each injection adjacent to the existing RPE tear. At the final follow-up visit, his CNV had regressed and visual acuity was maintained at 6/6, N6. No additional RPE tears were noted.
Pathogenesis of sequential RPE tears remains unclear. There is a need to look out for new RPE tears which can affect vision in a patient with neovascular AMD following CNV treatment.
报告1例玻璃体内注射雷珠单抗治疗新生血管性年龄相关性黄斑变性(AMD)后相继出现视网膜色素上皮(RPE)撕裂的病例。
回顾性观察病例。
一名75岁男性高血压患者被诊断为左眼患有活动性新生血管性AMD且存在既往RPE撕裂。其就诊时最佳矫正视力分别为右眼1米数指,<N36,左眼6/9,N8。右眼眼底有一个瘢痕化的脉络膜新生血管膜(CNV),伴有广泛硬性渗出。左眼眼底显示活动性CNV、视网膜下液和出血,黄斑中心凹下方有一个大的RPE撕裂,边缘卷曲。每月间隔行玻璃体内注射雷珠单抗(阿瓦斯汀®,爱尔康,0.5mg/0.05ml)治疗后,患者每次注射后在现有RPE撕裂附近又出现了2处RPE撕裂。在最后一次随访时,其CNV已消退,视力维持在6/6,N6。未发现额外的RPE撕裂。
相继出现RPE撕裂的发病机制尚不清楚。对于接受CNV治疗的新生血管性AMD患者,需要留意可能影响视力的新的RPE撕裂。
