INTRODUCTION
To assess the anatomical changes taking place in the choroid after a scleral buckle (SB) procedure for retinal detachment repair.
METHODS
This cross-sectional study looked at 23 adults with a history of unilateral retinal detachment repaired with a SB or other encircling element. The subjects underwent bilateral Enhanced Depth Spectral Domain Optical Coherence Tomography to image the choroid. The choroidal thickness (CT) was measured, and the non-operative eye was used as an internal control.
RESULTS
CT was measured to be 170.8 ± 60.9 µm (mean ± SD) in eyes with SBs compared to 175.1 ± 61.9 µm in non-operative eyes. There was no statistically significant difference between the two groups (mean 4.3 µm, 95% CI -8.7, 17.3, p value 0.4973, paired t test).
CONCLUSION
Placement of an SB as part of a surgery to repair retinal detachment did not significantly alter CT at the macula.
引言
评估巩膜扣带术（SB）用于视网膜脱离修复后脉络膜发生的解剖学变化。
方法
这项横断面研究观察了23例有单侧视网膜脱离病史且接受过SB或其他环扎术修复的成年人。受试者接受双侧增强深度谱域光学相干断层扫描以对脉络膜成像。测量脉络膜厚度（CT），并将未手术眼用作内部对照。
结果
有SB的眼睛的CT测量值为170.8±60.9μm（平均值±标准差），而未手术眼为175.1±61.9μm。两组之间无统计学显著差异（平均4.3μm，95%置信区间-8.7，17.3，p值0.4973，配对t检验）。
结论
作为视网膜脱离修复手术一部分的SB放置并未显著改变黄斑区的CT。
