A 61-year-old Japanese woman presented with impairment of her left vision due to macular schisis secondary to branch retinal vein occlusion. Her left vision was 20/50, and schisis was observed inferotemporally. She underwent phacoemulsification and aspiration, implantation of the intraocular lens, and removal of the epiretinal membrane and internal limiting membrane. Her visual acuity stabilized ~20/50 for two and a half years after the initial surgery. However, she developed macula-involving retinal detachment, and her visual acuity declined to counting fingers. She underwent pars plana vitrectomy and removal of the residual vitreous cortex together with the inner retina within the area of vein occlusion. After the removal of silicone oil and the addition of an encircling buckle, the retina remained attached and visual acuity improved to 20/60 at one year after the final surgery. The combination of rhegmatogenous and tractional detachment in the area of schisis was suspected, and vitrectomy with inner retinectomy was effective.
一名61岁的日本女性因视网膜分支静脉阻塞继发黄斑劈裂而出现左眼视力受损。她的左眼视力为20/50，在颞下象限观察到劈裂。她接受了超声乳化吸除术、人工晶状体植入术以及视网膜前膜和内界膜切除术。初次手术后两年半，她的视力稳定在约20/50。然而，她出现了累及黄斑的视网膜脱离，视力下降至仅能数指。她接受了玻璃体切除术，并在静脉阻塞区域内切除了残留的玻璃体皮质以及内层视网膜。在取出硅油并加用环扎带后，视网膜保持贴附，最终手术后一年视力提高到20/60。怀疑在劈裂区域存在孔源性和牵拉性视网膜脱离的联合情况，而玻璃体切除联合内层视网膜切除术是有效的。
