The condition of the posterior vitreous was determined in 56 eyes with central retinal vein occlusion (CRVO). Using a life-table analysis, it was studied in 56 eyes. The incidence of posterior vitreous detachment (PVD) in the CRVO eyes at the first vitreous examination did not differ significantly from that in 64 age-matched control eyes. However, the incidence of PVD in CRVO eyes increased from 39.3% at the first vitreous examination to 58.5% after 6 months, and to 69.6% 1 year from the examination. The incidence of PVD in CRVO eyes during follow-up was statistically higher than that of the controls (P = .009). The incidence of PVD after the first vitreous examination was significantly higher in eyes with hemorrhagic retinopathy than in eyes with venous stasis retinopathy (P = .04). In the 34 eyes with macular edema, the edema lasted significantly longer in those with vitreomacular attachment (VMA) at the first examination than in those without VMA at this time (P = .02). VMA may play an important role in the pathogenesis and chronicity of macular edema in CRVO.
对56只患有视网膜中央静脉阻塞（CRVO）的眼睛进行了玻璃体后部状况的评估。采用寿命表分析法对这56只眼睛进行了研究。在首次玻璃体检查时，CRVO患眼的玻璃体后脱离（PVD）发生率与64只年龄匹配的对照眼相比无显著差异。然而，CRVO患眼的PVD发生率从首次玻璃体检查时的39.3%增加到6个月后的58.5%，检查后1年时增加到69.6%。随访期间CRVO患眼的PVD发生率在统计学上高于对照组（P = 0.009）。首次玻璃体检查后，出血性视网膜病变患眼的PVD发生率显著高于静脉淤滞性视网膜病变患眼（P = 0.04）。在34只患有黄斑水肿的眼睛中，首次检查时有玻璃体黄斑粘连（VMA）的眼睛水肿持续时间明显长于此时无VMA的眼睛（P = 0.02）。VMA可能在CRVO黄斑水肿的发病机制和慢性化过程中起重要作用。
