摘要

目的基于光学相干断层血管造影(OCTA),探讨后巩膜加固手术对高度近视患者眼底结构和功能的影响。方法回顾性临床研究。选择2022年1月至2025年1月在成都中医药大学附属银眼医院行巩膜后加固手术的高度近视患者40例(41眼)。随访期包括术后3个月、6个月和1年。比较手术前后的关键指标:最佳矫正视力(BCVA)、眼轴长度(AL)、球面等效(SE)、视网膜厚度(RT)、脉络膜厚度(CT)、视网膜浅毛细血管丛密度(SCP)、视网膜深毛细血管丛密度(DCP)、脉络膜血管通畅指数(CVI)、脉络膜间质血管通畅指数(CSI)。结果共纳入患者40例(41眼),其中男性9例(9眼),女性31例(32眼),平均年龄42.05±18.71岁。末次随访时,患者AL明显缩短(P <;0.001), BCVA显著改善(P <;0.05), CT值显著升高(P <;0.05)。术后SCP也明显升高(P <;0.05)。此外,CVI和CSI术后明显升高(P <;0.05)。结论后巩膜加固通过机械加固实现轴向稳定,减轻玻璃体对视网膜和脉络膜的牵引力,提高视力,改善脉络膜视网膜微循环,优化眼底结构。

Optical coherence tomography angiography study on retinochoroidal thickness and blood flow changes after posterior scleral reinforcement surgery

Purpose

Based on optical coherence tomography angiography (OCTA), we investigate the effects of posterior scleral reinforcement surgery on the fundus structure and function in patients with high myopia.

Methods

Retrospective clinical study. Forty cases (41eyes) of high myopia patients who underwent posterior scleral reinforcement surgery at Chengdu University of Traditional Chinese Medicine Affiliated Silver Eye Hospital from January 2022 to January 2025 were selected. Follow-up periods included postoperative 3 months, 6 months, and 1 year. Key indicators before and after surgery were compared, including best-corrected visual acuity (BCVA), axial length (AL), spherical equivalent (SE), retinal thickness (RT), choroidal thickness (CT), and Superficial retinal capillary plexus density (SCP), deep retinal capillary plexus density (DCP), choroidal vascularity index (CVI), choroidal stromal vascularity index (CSI).

Results

The study included 40 patients (41 eyes), comprising 9 male patients (9 eyes) and 31 female patients (32 eyes), with a mean age of 42.05 ± 18.71 years.At the last follow-up, patients showed significantly shortened AL (P < 0.001), significantly improved BCVA (P < 0.05), and significantly increased CT (P < 0.05).SCP also exhibited significant postoperative increases (P < 0.05). Additionally,CVI and CSI showed significant postoperative elevation (P < 0.05).

Conclusion

This study demonstrates that posterior scleral reinforcement achieves axial stabilization through mechanical reinforcement, mitigates vitreous traction forces on the retina and choroid, enhances visual acuity, improves choroidoretinal microcirculation, and optimizes fundus architecture.
