Abstract:【Objective】 To investigate the correlation between different optical coherence tomography (OCT) classifications of retinal vein occlusion macular edema (RVO-ME) and serum vascular endothelial growth factor (VEGF) levels. 【Methods】 Clinical data of 138 patients (138 eyes) with RVO-ME diagnosed and treated in the ophthalmology department of our hospital from December 2022 to December 2024 were retrospectively analyzed. According to the site of retinal vein occlusion, patients were divided into central retinal vein occlusion group and branch retinal vein occlusion group. According to OCT features, RVO-ME patients were classified into diffuse retinal thickening type group (n=25), serous retinal detachment type group (n=58), and cystoid macular edema type group (n=55). Meanwhile, 50 patients (50 eyes) undergoing cataract surgery who were diagnosed and treated in our ophthalmology department and excluded from fundus diseases were selected as the control group. Serum VEGF levels were measured and compared among all groups. 【Results】 Serum VEGF levels in both central retinal vein occlusion group and branch retinal vein occlusion group were significantly higher than those in the control group (P<0.05). There were statistically significant differences in the distribution of central retinal vein occlusion and branch retinal vein occlusion among diffuse retinal thickening type, serous retinal detachment type and cystoid macular edema type RVO-ME patients (P<0.05). Statistically significant differences were found in serum VEGF levels among RVO-ME patients with different OCT classifications (P<0.05). 【Conclusion】 Serum VEGF levels differ in RVO-ME patients with different OCT classifications, and are closely related to the site of retinal vein occlusion and the type of macular edema, suggesting that VEGF may play an important role in the pathogenesis and progression of RVO-ME.
