To describe a case of capsular bag distention syndrome with opaque contents noted 5 years after intraocular lens implantation.
A 66-year-old man underwent phacoemulsification after circular capsulorhexis and intraocular lens implantation in the left eye. Five years later, the posterior capsule was vaulted far posteriorly, the capsular opening was apparently sealed by the lens optic, and the bag contents were slightly opacified. Two years later, the contents of the hyperdistended capsular bag showed intensified opacity, causing definite blurred vision.
The opacified medium was emptied from the capsular bag posteriorly into the vitreous after Nd:YAG laser capsulotomy, and the distended capsule was restored.
Our findings suggest that the contents were collagens produced by residual lens epithelial cells or necrotic and/or apoptotic autolyzed lens epithelial cells.
描述一例人工晶状体植入术后5年出现的伴有不透明内容物的囊袋扩张综合征病例。
一名66岁男性在左眼行环形撕囊及人工晶状体植入术后接受了超声乳化手术。5年后，后囊膜向后方明显膨隆，囊袋开口明显被晶状体光学部封闭，囊袋内容物略有混浊。2年后，高度扩张的囊袋内容物混浊加重，导致视力明显模糊。
钕:钇铝石榴石激光晶状体后囊切开术后，不透明物质从囊袋后方排入玻璃体，扩张的囊袋恢复原状。
我们的研究结果表明，这些内容物是由残留的晶状体上皮细胞或坏死和/或凋亡自溶的晶状体上皮细胞产生的胶原蛋白。
