目的：报道节段性巩膜扣带术后黄斑中心凹下脉络膜厚度的光谱域光学相干断层扫描的形态变化。设计：回顾性观察病例系列。方法：采用节段性巩膜扣带术治疗孔源性视网膜脱离20例(21眼)。所有患者均于术前、术后1周、1个月、3个月测量中心凹下脉络膜厚度。结果：手术眼术前平均中心凹下脉络膜厚度为239.2±91.0um m，术后1周、1个月、3个月平均中心凹下脉络膜厚度分别为267.6±96.8m m、250.6±95.8m m、239.4±95.6m m。术前中心凹下脉络膜厚度与术后1周和术后1个月的脉络膜厚度差异有统计学意义(P<；.01，P=0.03，ANOVA)，与术后3个月的脉络膜厚度差异无统计学意义(P>；.99，ANOVA)。巩膜扣带术前后1周脉络膜厚度变化差异无统计学意义(n=8，P=.589，双因素方差分析)。结论：巩膜扣带术后黄斑中心凹下脉络膜厚度可能有暂时性改变。这可能是可逆性亚临床脉络膜微循环障碍的结果。《眼科杂志》2012；154：893-900。(C)2012年由Elsevier Inc.保留所有权利。)
PURPOSE: To report the morphologic changes of the subfoveal choroidal thickness using spectral-domain optical coherence tomography following segmental scleral buckling.DESIGN: Retrospective, observational case series.METHODS: The study included 21 eyes of 20 patients who underwent segmental scleral buckling for the treatment of rhegmatogenous retinal detachment. All patients underwent the measurements of the subfoveal choroidal thickness preoperatively and 1 week, 1 month, and 3 months after the surgery. The changes in choroidal thickness, 4 mm from the fovea, before and 1 week after surgery were analyzed in the buckled and unbuckled side.RESULTS: The preoperative mean subfoveal choroidal thickness of operated eyes was 239.2 +/- 91.0 mu m. The postoperative mean subfoveal choroidal thicknesses of operated eyes at 1 week, 1 month, and 3 months were 267.6 +/- 96.8 mu m, 250.6 +/- 95.8 mu m, and 239.4 +/- 95.6 mu m, respectively. There were significant differences between preoperative subfoveal choroidal thickness and 1-week-postoperative and 1-month-postoperative subfoveal choroidal thicknesses (P < .01, P = .03, ANOVA), and there was no significant difference between subfoveal choroidal thicknesses preoperatively and 3 months postoperatively (P > .99, ANOVA). The changes in choroidal thickness of the buckled and unbuckled side preoperatively and 1 week postoperatively were not significantly different (n = 8, P = .589, 2-way ANOVA).CONCLUSION: The subfoveal choroidal thickness may change temporarily following segmental scleral buckling surgery. This may be the result of reversible subclinical microcirculatory dysfunction of the choroid. (Am J Ophthalmol 2012;154:893-900. (C) 2012 by Elsevier Inc. All rights reserved.)
