    Author: Weng N, Wei W, Zhu X.
    Journal: Zhonghua Yan Ke Za Zhi; 2001 Nov; 37(6):425-7. PubMed ID: 11840748.
    Abstract:
    OBJECTIVE: To investigate the morphologic structures of vitreous hemorrhage that may be beneficial to its treatment. METHODS: The clinical data of 74 cases (79 eyes) with vitreous hemorrhage resulting from proliferative diabetic retinopathy, retinal vasculitis and retinal vein occlusion in December 1995 to January 2000 and having undergone vitrectomy were studied retrospectively, which focused on the morphologic characteristics of vitreous body by B-scan, surgical microscopy and surgical manipulation, to evaluate the relation of retina and vitreous body in order to discern the relationships among the retina, neovascular fibromembrane and the posterior hyaloid surface. RESULTS: Posterior vitreous detachment (PVD) in various degrees was observed in all the cases. The morphologic character was classified as the complete and partial vitreous detachment. The latter one can be subdivided into "V", "L" types and posterior vitreoschisis that was not rarely seen in the proliferative phase of ischemic retinopathy. CONCLUSIONS: To evaluate the characteristics of posterior vitreous detachment and vitreoschisis may provide valuable information for vitreoretinal surgery, elevate the rate of success and improve the prognosis of the surgery.
