Purpose This study aimed to assess the short-term changes of macular microstructures following anti-VEGF and anti-inflammatory therapies in patients with macular edema secondary to retinal vein occlusion (RVO-ME). Patients and Methods In this retrospective study, 70 eyes of 70 patients with RVO-ME were divided into the anti-VEGF (Group A, 35 eyes) and anti-inflammatory (Group B, 35 eyes) treatment groups. All patients underwent best-corrected visual acuity (BCVA) assessment, intraocular pressure (IOP) assessment, slit lamp, fundus fluorescein angiography (FA), scanning laser ophthalmoscopy (SLO), and spectral-domain optical coherence tomography (SD-OCT). Group A received intravitreal injection of 0.05 mL anti-VEGF antibodies (Lucentis ® or Aflibercept ® ) monthly for 3 consecutive months, while Group B received 0.7 mg dexamethasone (Ozurdex ® ) single intravitreal injection. BCVA and SD-OCT biomarkers were recorded at baseline and 3 months after the first injection. Changes of BCVA and SD-OCT biomarkers following these treatments were compared between the two groups. Results BCVA and SD-OCT biomarkers, except choroidal thickness, in both groups were significantly improved after treatment (all P < 0.01). At 3 months, the height of serous retinal detachment (SRD) was markedly lower ( P = 0.006), with significantly less hyperreflective dots (HRD, P = 0.037) in Group B compared with Group A. Other SD-OCT biomarkers and BCVA were not significantly different between the two groups (all P > 0.05). Conclusion Anti-VEGF and anti-inflammatory therapies are both effective in RVO-ME, with improvement in BCVA and SD-OCT biomarkers. Anti-inflammatory therapy may be more effective than anti-VEGF therapy in SRD and HRD resolution.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
