Central retinal artery occlusion (CRAO) is a vision-threatening emergency with no established effective treatment. Prostaglandin E (PGE), known for its vasodilatory and cytoprotective properties, may offer therapeutic benefits for retinal ischemia.
In this retrospective study, we compared visual outcomes between CRAO patients who received intravenous PGE within 24 hours of symptom onset (followed by oral administration) and those who received conventional therapy. PGE was administered intravenously for 5 days.
At one month, the PGE group showed significantly better best-corrected visual acuity compared to the control group. Baseline structural retinal parameters, including maximal retinal thickness (MRT) and central retinal thickness (CRT), did not differ significantly between groups. In the PGE group, baseline MRT was negatively correlated with visual acuity at one month. Retinal arteriovenous diameters showed no significant change post-treatment. No adverse events were observed in either group.
Early administration of PGE may improve visual outcomes in CRAO. These findings support further investigation into PGE as a potential treatment for acute retinal ischemia.
视网膜中央动脉阻塞(CRAO)是一种威胁视力的急症,尚无已确立的有效治疗方法。前列腺素E(PGE)以其血管舒张和细胞保护特性而闻名,可能对视网膜缺血具有治疗益处。
在这项回顾性研究中,我们比较了在症状发作后24小时内接受静脉注射PGE(随后口服给药)的CRAO患者与接受传统治疗的患者的视力结果。PGE静脉注射5天。
在1个月时,PGE组的最佳矫正视力明显优于对照组。两组之间的基线视网膜结构参数,包括最大视网膜厚度(MRT)和中央视网膜厚度(CRT),没有显著差异。在PGE组中,基线MRT与1个月时的视力呈负相关。视网膜动静脉直径在治疗后没有显著变化。两组均未观察到不良事件。
早期给予PGE可能改善CRAO的视力结果。这些发现支持进一步研究PGE作为急性视网膜缺血的潜在治疗方法。
