摘要

目的：评价孔源性视网膜脱离（RRD）巩膜屈曲（SB）术后眼内脉络膜结构和血管的变化，并与正常眼和对照眼进行比较。方法：84只眼进行回顾性观察研究，其中研究组32只眼为因RRD而行SB的患者，32只眼为同组患者，20只眼为正常对照。测量并比较三个研究组的脉络膜结构和光学相干断层血管造影（OCTA）参数。结果：研究组的平均脉络膜总面积（0.6816±0.03188 mm2）与对照组（0.7199±0.03056 mm2）和对照组（0.7154±0.17160 mm2）相当。研究组平均外腔面积（0.4089±0.00442 mm2）明显低于对照组（0.4437±0.00701 mm2）和对照组（0.4475±0.00442 mm2）（P分别为0.042和0.047）。与正常眼和对照组相比，既往SB眼的脉络膜血管指数（CVI）和OCTA参数无显著差异。结论：SB对CVI、脉络膜血管和OCTA参数无明显影响。

Choroidal and Retinal OCTA Parameters after Scleral Buckling.

Purpose: To evaluate choroidal structure and vasculature in eyes following scleral buckling (SB) for rhegmatogenous retinal detachment (RRD) compared with fellow eyes and control eyes.

Methods: This retrospective observational study was performed on 84 eyes: 32 eyes in the study group consisting of patients who had undergone SB due to RRD, 32 fellow eyes of the same patients, and 20 normal control eyes. Choroidal structures and optical coherence tomography angiography (OCTA) parameters were measured and compared among the three study groups.

Results: In the study group, the mean total choroidal area (0.6816 $\pm$ 0.03188 mm²) was comparable to the fellow eyes (0.7199 $\pm$ 0.03056 mm²) and the control group (0.7154 $\pm$ 0.17160 mm²). Mean outer luminal area was significantly lower in the study group (0.4089 $\pm$ 0.00442 mm²) than in the fellow eyes (0.4437 $\pm$ 0.00701 mm²) and the control group (0.4475 $\pm$ 0.00442 mm²) (P = 0.042, and 0.047, respectively). The choroidal vascularity index (CVI) and OCTA parameters were not significantly different in eyes with prior SB compared to the fellow eyes and the control group.
