To identify the morphologic characteristics of vitreous especially vitreoschisis in vitreous hemorrhage, aiming at discussing the mechanism and clinical importance of vitreoschisis.
Eighty-eight cases (97 eyes) of vitreous hemorrhage were observed among which 32 cases (38 eyes) resulting from PDR, 28 cases (30 eyes) resulting from retinal vasculitis and 28 cases (29 eyes) resulting from retinal vein occlusion. All cases had B-scan examination, some had color Doppler examination. Images were compared with the finding in vitre-ctomy.
Vitreoschisis occurred in 18 cases (47.4%) in PDR group, 10 cases (33%) in retinal vasculitis group and 4 cases (13.8%) in retinal vein occlusion group.
Vitreoschisis may occur in different kind of vitreous hemorrhage. Recognition of vitreoschisis may aid to complete vitrectomy and reduce some complication after surgery.
明确玻璃体尤其是玻璃体劈裂在玻璃体积血中的形态学特征，旨在探讨玻璃体劈裂的机制及临床意义。
观察88例（97只眼）玻璃体积血患者，其中32例（38只眼）由增殖性糖尿病视网膜病变引起，28例（30只眼）由视网膜血管炎引起，28例（29只眼）由视网膜静脉阻塞引起。所有病例均行B超检查，部分行彩色多普勒检查。将图像与玻璃体切除术中的发现进行比较。
增殖性糖尿病视网膜病变组18例（47.4%）发生玻璃体劈裂，视网膜血管炎组10例（33%），视网膜静脉阻塞组4例（13.8%）。
不同类型的玻璃体积血均可能发生玻璃体劈裂。认识玻璃体劈裂有助于玻璃体切除术的顺利进行并减少术后一些并发症。
