摘要

目的

研究光谱域光学相干断层扫描（SD⁃OCT)下视网膜中央动脉阻塞患者（CRAO）特定视网膜厚度变化及其与临床特征的相关性。

方法

回顾性收集91例CRAO患者临床资料。根据SD⁃OCT检查将CRAO分为3个等级（不完全、次全、完全），测量并比较各组患者及对照组特定视网膜厚度

分析其与入院视力、出院视力的相关性。

结果

CRAO各组黄斑中心凹厚度（CFT)、视网膜最内层（IMRL)、视网膜中层（MRL)以及视网膜外层（ORL)厚度均显著高于同组CRAO患者对侧健眼（

0.001）。CRAO阻塞程度增加，CFT、IMRL、MRL、ORL厚度明显增加（

0.001）。CRAO患者入院视力logMAR与分级、CFT、IMRL、MRL厚度呈正相关（

Abstract

Objective

To investigate selected retinal layers in patients with acute central retinal artery occlusion (CRAO) under spectral⁃domain optical coherence tomography (SD⁃OCT) examination

and further analyze the correlation between retinal thickness and clinical characteristics in CRAO patients.

Methods

Clinical data from 91 patients with acute CRAO were retrospectively collected. Based on the SD⁃OCT image

CRAO was categorized into three grades (incomplete

subtotal

and total occlusion). The thickness of selected retinal layers was measured and compared across the three grades and against the contralateral eyes (controls). The relationship between selected retinal thickness and clinical characteristics was analyzed.

Results

The thickness of central foveal thickness (CFT)

the innermost retinal layer (I

MRL)

the middle retinal layer (MRL)

and the outer retinal layer (ORL) in CRAO patients significantly differed from that of the contralateral eye (

0.001). As the severity of CRAO increased

the thickness of CFT

IMRL

MRL

and ORL increased significantly

with a significant difference (

0.001). The baseline visual acuity (logMAR) was positively correlated with CRAO grading

as well as the thickness of CFT

IMRL

and MRL in CRAO patients (

baseline visual acuity (logMAR)

and CFT thickness in CRAO patients

and negatively correlated with thrombolytic therapy (

Conclusion

SD⁃OCT can reveal the characteristic pathological retinal changes in CRAO patients. CFT thickness is positively associated with baseline visual acuity and discharge visual acuity.
