Forty-six cases of vitreous loss during planned extracapsular cataract extraction salvaged by anterior vitrectomy and primary anterior chamber lens implantation were compared in a retrospective cohort study with 92 individually matched controls. The postoperative visual outcome for cases with vitreous loss was significantly poorer than that for controls even after adjustment for confounding variables. Part of this visual morbidity was explained by cystoid macular oedema and retinal detachment, but even after adjusting for these two complications visual outcome remained worse among cases than controls. There was a significantly higher incidence of clinically apparent cystoid macular oedema amongst cases compared with controls (20% versus 1%). Two retinal detachments occurred among the cases but this difference in incidence was not statistically significant.
在一项回顾性队列研究中，对46例在计划的囊外白内障摘除术中发生玻璃体丢失并通过前部玻璃体切除术和一期前房人工晶状体植入术挽救的病例与92例个体匹配的对照进行了比较。即使在对混杂变量进行调整之后，玻璃体丢失病例的术后视力结果仍显著差于对照组。部分视力损害可由黄斑囊样水肿和视网膜脱离来解释，但即使在对这两种并发症进行调整之后，病例组的视力结果仍比对照组差。与对照组相比，病例组中临床明显的黄斑囊样水肿发生率显著更高（20% 对1%）。病例组中有两例发生视网膜脱离，但这一发生率差异无统计学意义。
