新发缺血性脑卒中患者的视网膜黄斑区OCT特征

OCT characteristics of retinal macular region in patients with new-onset ischemic stroke

目的:测量黄斑区视网膜神经节细胞层和内界膜-视网膜色素上皮层厚度,分析其与新发缺血性脑卒中的相关性。方法:采用前瞻性研究,选择2021年12月至2022年3月在潍坊医学院附属医院体检的健康者30例(60眼)为对照组(A组);选择同期收治且年龄匹配的新发缺血性脑卒中患者30例(60眼)为卒中组(B组)。比较两组黄斑区神经节细胞层(ganglion cell layer,GCL)和内界膜-视网膜色素上皮层(inner limiting membrane-Retinal pigment epithelium,ILM-RPE)厚度及平均GCL厚度/ILM-RPE平均容积厚度(GCL/ILM-RPE厚度比)。结果:共纳入120只眼,A、B组分别60只眼。A组的平均GCL为(83.5±4.7)μm,B组的平均GCL厚度为(78.7±10.5)μm,组间比较差异有统计学意义(P<0.001)。A组的GCL最小厚度为(80.4±4.4)μm,B组的GCL最小厚度为(70.7±16.3)μm,组间比较差异有统计学意义(P<0.001)。A组的ILM-RPE中心子区厚度为(247.5±19.8)μm,B组的ILM-RPE中心子区厚度为(241.6±36.3)μm,组间比较差异无统计学意义(P=0.393)。A组的ILM-RPE平均容积厚度为278.4±9.8μm,B组的ILM-RPE平均容积厚度为(278.5±15.3)μm,组间比较差异无统计学意义(P=0.448)。A组的GCL/ILM-RPE厚度比为0.300 3±0.012 2,B组的GCL/ILM-RPE厚度比为0.286 2±0.028 6,组间比较差异有统计学意义(P<0.001)。结论:缺血性脑卒中影响GCL厚度和GCL/ILM-RPE厚度比,GCL厚度和GCL/ILM-RPE厚度比与新发缺血性脑卒中可能有关。

Objective: To measure the thickness of retinal ganglion cell layer and inner limiting membrane-retinal pigment epithelium layer in the macular region, and analyze its correlation with new-onset ischemic stroke. Methods: By using a prospective study, 30 healthy subjects (60 eyes) who underwent physical examination in Affiliated Hospital of Weifang Medical University from December 2021 to March 2022 were selected as the control group (Group A). Thirty age-matched patients with new-onset ischemic stroke admitted at the same time (60 eyes) were selected as the stroke group (Group B). The ganglioncelllayer (GCL) and innerlimitingmembrane-Retinalpigmentepithelium (ILM-RPE) were compared between the two groups. It included the thickness and mean GCL thickness/Mean Volume thickness of ILM-RPE (GCL/ILM-RPE thickness ratio). Results: A total of 120 eyes were included, with 60 eyes in group A and B. The average GCL thickness in group A was (83.5±4.7) μm, and the average GCL thickness in group B was (78.7±10.5) μm, and the difference between groups was statistically significant (P <0.001). The minimum thickness of GCL in group A was (80.4±4.4) μm, and the minimum thickness of GCL in group B was (70.7±16.3) μm, showing statistical significance (P <0.001). The thickness of the central subregion of ILM-RPE in group A was (247.5±19.8) μm, and the thickness of the central subregion of ILM-RPE in group B was (241.6±36.3) μm, and the difference was not statistically significant between two groups (P =0.393). The mean volumetric thickness of ILM-RPE in group A was (278.4±9.8) μm, and the mean volumetric thickness of ILM-RPE in group B was (278.5±15.3) μm, and the difference was not statistically significant (P=0.448). The GCL/ILM-RPE thickness ratio of group A was (0.300 3±0.012 2), and that of group B was (0.286 2±0.028 6), showing a statistical difference between groups (P <0.001). Conclusion: Ischemic stroke affects the GCL thickness and the thickness ratio of GCL/ILM-RPE, which may be related to new-onset ischemic stroke.
