I investigated whether posterior vitreous detachment is invariably associated with retinal detachment in the elderly caused by flap retinal tears. Of 97 eyes which underwent vitrectomy, Weiss' ring was not observed in 10 eyes during both the preoperative slit lamp microscope examination and the intraoperative surgical microscope observation. I proved by surgically detaching the posterior vitreous in 5 out of those 10 eyes that the posterior vitreous had not yet become detached before the operation. My results suggest that posterior vitreous detachment may not be associated with 5 to 10% of cases of retinal detachment caused by flap retinal tears.
我研究了在老年人中，后玻璃体脱离是否总是与瓣状视网膜裂孔引起的视网膜脱离相关。在接受玻璃体切除术的97只眼中，术前裂隙灯显微镜检查和术中手术显微镜观察时，有10只眼未观察到魏斯环。我通过手术分离其中10只眼中的5只眼的后玻璃体，证明在手术前这些眼的后玻璃体尚未脱离。我的结果表明，后玻璃体脱离可能与5%至10%的瓣状视网膜裂孔引起的视网膜脱离病例无关。
