摘要

目的：评估视网膜中央动脉闭塞（CRAO）患者的视网膜循环情况：对 42 名 CRAO 患者（42 眼，平均年龄（66.0±14.0）岁）进行首次就诊时的最佳矫正视力（BCVA）、荧光素血管造影（FA）和激光斑点血流成像（LSFG）值测量。在基线、1 周、1、3 和 6 个月时进行 LSFG 测量；测量平均模糊率血管面积与平均模糊率组织面积（MV-MT）之间的差值，反映视网膜血管血流量。FA 测量了动静脉通过（AV）时间。研究了 MV-MT 和 BCVA 的时程变化以及 MV-MT 和最终 BCVA 之间的关系：结果：MV-MT 与 AV 时间（PConclusions：1个月内视网膜循环明显改善；年轻患者视网膜循环改善程度更好。基线 BCVA 和 1 个月内的视网膜循环与最终 BCVA 相关。

TIME-COURSE RETINAL CIRCULATION CHANGES IN EYES WITH CENTRAL RETINAL ARTERY OCCLUSION USING LASER SPECKLE FLOWGRAPHY.

Purpose: To evaluate retinal circulation in eyes with central retinal artery occlusion (CRAO).

Methods: The best-corrected visual acuity (BCVA), fluorescein angiography (FA), and laser speckle flowgraphy (LSFG) values were measured at the first visit in 42 patients with CRAO (42 eyes; mean age, 66.0±14.0 years. LSFG was performed at baseline, 1 week, and 1, 3, and 6 months; the difference between the mean blur rate vessel area and mean blur rate tissue area (MV-MT), reflecting the retinal vessel blood flow, was measured. FA measured the arteriovenous passage (AV) time. Time-course changes in the MV-MT and BCVA and the relationship between MV-MT and final BCVA were examined.

Results: MV-MT was significantly correlated with AV time (P<0.001). The MV-MT increased significantly after 1, 3, and 6 months (P<0.001). The VA improved significantly until 1 month (P<0.01). Multivariate analysis showed a significant correlation between the baseline BCVA (P<0.001) and MV-MT at 1 month (P=0.01) and the final BCVA. Age and MV-MT were significantly negatively correlated at 1 month (P<0.001).

Conclusions: The retinal circulation improved significantly within 1 month; younger patients had better retinal circulation improvement. The baseline BCVA and retinal circulation within 1 month were correlated with the final BCVA.
