PURPOSE
To describe two cases of late Capsular Bag Distention syndrome (CBDS) and posterior capsular opacification (PCO) as documented on Pentacam.
DESIGN
Case series.
METHODS
A 55-year-old male and a 72-year-old female presented three years after phacoemulsification and intraocular lens (IOL) implantation with a complaint of decreased vision. Scheimpflug imaging was done using Pentacam. Patients underwent Nd:YAG capsulotomy for PCO, and postcapsulotomy capsular bag dynamics were imaged on Pentacam.
RESULTS
Three years after phacoemulsification, patients presented with blurred vision and posterior bowing of opacified posterior capsule. Anterior capsular opening was apparently sealed by lens optic, and space between IOL and opacified posterior capsule was filled with turbid fluid. Nd:YAG laser capsulotomy was done. All findings, including collapse of distended bag, were precisely documented on Scheimpflug images.
CONCLUSIONS
Pentacam Scheimpflug imaging is a useful technique to diagnose and document the presence and progress of CBDS and PCO.
目的
描述两例经Pentacam记录的迟发性囊袋扩张综合征（CBDS）和后囊膜混浊（PCO）病例。
设计
病例系列。
方法
一名55岁男性和一名72岁女性在白内障超声乳化吸除术和人工晶状体（IOL）植入术后三年出现视力下降前来就诊。使用Pentacam进行眼前节分析成像。患者因PCO接受了Nd:YAG激光后囊切开术，并在Pentacam上对后囊切开术后的囊袋动态进行成像。
结果
白内障超声乳化吸除术后三年，患者出现视力模糊和混浊后囊膜向后膨隆。前囊开口明显被晶状体光学部封闭，IOL与混浊后囊膜之间的间隙充满浑浊液体。进行了Nd:YAG激光后囊切开术。所有发现，包括扩张囊袋的塌陷，均在眼前节分析图像上得到精确记录。
结论
Pentacam眼前节分析成像技术对于诊断和记录CBDS和PCO的存在及进展是一项有用的技术。
