Abstract

Purpose: To explore the changes in the corneal endothelium in patients who receive multiple anti-vascular endothelial growth factor (anti-VEGF) or steroid injections for posterior segment pathology.

Methods: This cross-sectional study recruits subjects treated with intravitreal anti-VEGF or sustained-release dexamethasone for macular edema due to retinal vein occlusion. Corneal endothelium and corneal thickness were measured in the treated eye using a corneal endothelial microscope. The study variables include age, endothelial cell density (ECD), coefficient of variation (CV) of cell size, percentage of hexagonality (HEX%), and intraocular pressure (IOP) change 30 min after injection. These variables were analyzed using multiple linear regression analysis.

Results: A total of 108 diseased eyes were treated with a variable number (from 4 to 28) of intravitreal injections between January 2020 and December 2023. The mean total number of intravitreal injections was 12.8/eye. Multiple linear regression analysis showed an inverse relationship between ECD and age (β = -9.74, 95% confidence interval [CI] [-8.01, -10.24], P < 0.05) and total number of injections (β = -17.11, 95% CI [-16.44, -18.37], P < 0.05). An inversion relationship also exists between HEX% and age (β = -0.17, 95% CI [-0.11, -0.23], P < 0.05) and total number of injections (β = -0.45, 95% CI [-0.37, -0.54], P < 0.05). A direct relationship exists between CV and age (β =0.29, 95% CI [0.19, 0.40], P < 0.05) and total number of injections (β =0.54, 95% CI [0.45, 0.63], P < 0.05). The mean IOP difference between the injected and contralateral eye 30 min postinjection was +6.4 ± 3 mmHg (P < 0.05).

Conclusion: A greater number of intravitreal injections is associated with a lower ECD, lower HEX, and higher CV in the treated eyes.

多次玻璃体内注射相关的角膜内皮细胞改变。

目的：探讨抗血管内皮生长因子（anti-VEGF）或类固醇注射治疗后段病变患者角膜内皮的变化。方法：本横断面研究招募了接受玻璃体内抗vegf或缓释地塞米松治疗视网膜静脉阻塞引起的黄斑水肿的受试者。用角膜内皮显微镜测量治疗眼的角膜内皮和角膜厚度。研究变量包括年龄、内皮细胞密度（ECD）、细胞大小变异系数（CV）、六边形百分比（HEX%）、注射后30min眼内压（IOP）变化。对这些变量进行多元线性回归分析。结果：在2020年1月至2023年12月期间，共有108只患病的眼睛接受了玻璃体内注射，数量不等（从4到28）。平均总玻璃体内注射次数为12.8次/眼。多元线性回归分析显示，ECD与年龄（β = -9.74, 95%可信区间[CI] [-8.01, -10.24], P < 0.05）和总注射次数（β = -17.11, 95% CI [-16.44, -18.37], P < 0.05）呈负相关。HEX%与年龄（β = -0.17, 95% CI [-0.11, -0.23], P < 0.05）和总注射次数（β = -0.45, 95% CI [-0.37, -0.54], P < 0.05）呈负相关。CV与年龄（β =0.29, 95% CI [0.19, 0.40], P < 0.05）和总注射次数（β =0.54, 95% CI [0.45, 0.63], P < 0.05）有直接关系。注射后30min注射眼与对侧眼的平均IOP差值为+6.4±3 mmHg （P < 0.05）。结论：较多的玻璃体内注射与较低的ECD、较低的HEX和较高的CV有关。
