Here we report a case of traction retinal detachment (TRD) associated with congenital retinal vascular hypoplasia localized in the superotemporal quadrant that was treated with vitrectomy.
A 58 year-old female presented with a gradual decrease of visual acuity (VA) and distorted vision in her left eye. She had a past history of amblyopia in her left eye from early childhood, and a previous examination performed at a nearby hospital revealed that the corrected visual acuity (VA) in that eye was 0.15. Upon initial examination, no abnormal findings were observed in her right eye, yet optic-disc traction and macular rotation with a folded TRD extending superotemporally from the macular region was observed in her left eye. Fluorescein fundus angiography showed a retinal nonperfused area localized in the superotemporal quadrant surrounded by a retinal avascular area. The optic disc in her left eye was smaller than that in her right eye. Vitrectomy was performed to remove the proliferative membrane and created an artificial posterior vitreous detachment (PVD). Following surgery, the patient's corrected VA improved from 0.04 to 0.1.
The present case was likely to be TRD caused by PVD in the presence of localized congenital retinal vascular hypoplasia secondary to optic-disc hypoplasia.
在此我们报告一例与先天性视网膜血管发育不全相关的牵引性视网膜脱离（TRD）病例，病变位于颞上象限，采用玻璃体切除术进行治疗。
一名58岁女性，左眼视力逐渐下降且视物变形。她自幼左眼有弱视病史，附近医院之前的检查显示该眼矫正视力（VA）为0.15。初诊时，右眼未发现异常，但左眼可见视盘牵引及黄斑旋转，伴有从黄斑区颞上方延伸的折叠性TRD。荧光素眼底血管造影显示视网膜无灌注区位于颞上象限，周围为视网膜无血管区。她左眼的视盘比右眼小。行玻璃体切除术以切除增殖膜并造成人工玻璃体后脱离（PVD）。术后，患者的矫正视力从0.04提高到了0.1。
本病例可能是在视神经盘发育不全继发局部先天性视网膜血管发育不全的情况下，由PVD引起的TRD。
