Abstract:
Objective To analyze the effect of baseline cytokines in aqueous humor in predicting the improvement of the central macular thickness(CMT)and best corrected visual acuity(BCVA)of patients with macular edema secondary to retinal vein obstruction(RVO-ME)after anti-vascular endothelial growth factor(VEGF)treatment for 3 months.Meth-ods Totally 30 eyes of 30 patients initially diagnosed with RVO-ME in the Affiliated Eye Hospital of Nanjing Medical Uni-versity from October 2021 to January 2023 were enrolled.Aqueous humor was collected by anterior chamber puncture be-fore the anti-VEGF drug injection.The levels of 11 cytokines in aqueous humor,including VEGF,intercellular adhesion molecule(ICAM)-1,interleukins(ILs)and interferon-γ(IFN-γ),were measured by Luminex xMAP technology.The cor-relation between baseline aqueous humor cytokine levels and CMT,BCVA(logMAR)as well as their changes(difference between baseline and anti-VEGF treatment for 3 months)in RVO-ME patients was analyzed;the correlation between CMT and BCVA(logMAR)was analyzed at baseline and 3 months after anti-VEGF treatment.CMT and BCVA responders were defined as patients with 50％or more reduction in CMT and BCVA(logMAR)from baseline to the third month.A Logistic regression model was used to analyze the relationship between baseline aqueous humor cytokines and RVO-ME patients be-coming CMT or BCVA responders after 3 months of anti-VEGF treatment.Results Compared with baseline,the CMT sig-nificantly decreased and BCVA significantly improved in RVO-ME patients after anti-VEGF treatment for 3 months(both P＜0.001).The CMT was positively correlated with BCVA(logMAR)of RVO-ME patients at baseline and after anti-VEGF treatment for 3 months(P=0.026,0.002).At baseline,the levels of VEGF and IL-8 of RVO-ME patients were positively correlated with CMT(P=0.032,0.035);the levels of IL-6 and IL-8 were positively correlated with BCVA(logMAR)(P=0.018,0.002).The baseline IL-8 level in RVO-ME patients was negatively associated with the change in CMT(P=0.024).Logistic regression analysis showed that elevated baseline ICAM-1 level could increase the risk of RVO-ME patients becom-ing BCVA non-responders after 3 months of anti-VEGF treatment(P=0.023).Conclusion Baseline IL-8 and ICAM-1 may be predictors of CMT and BCVA improvement after anti-VEGF treatment of RVO-ME.
