Comparison of Intravitreal Bevacizumab and Aflibercept Injections for Central Serous Chorioretinopathy

ABSTRACT

Purpose@#We examined differences in the treatment effects of intravitreal bevacizumab injections and intravitreal aflibercept injections in patients with central serous chorioretinopathy. @*Methods@#This retrospective analysis included 51 eyes of 49 patients who received intravitreal anti-vascular endothelial growth factor agent injections after initial diagnosis with central serous chorioretinopathy. The patients were divided into two groups one received an intravitreal bevacizumab injection, and another one received an intravitreal aflibercept injection. Patients with no reaction to treatment or a worsened condition, received repeat treatment with the same therapy. After treatment, patients were monitored for >3 months. Data were collected regarding best- corrected visual acuity (BCVA), subfoveal choroidal thickness, injection number, and treatment duration. @*Results@#Both intravitreal bevacizumab injections and intravitreal aflibercept injections led to significant differences in BCVA (p < 0.0001, p = 0.001) and subfoveal choroidal thickness (p < 0.0001, p = 0.011), compared between before and after treatment. However, no differences between groups were observed in mean change of BCVA or subfoveal choroidal thickness. In addition, there were no differences between groups in injection number and treatment duration. @*Conclusions@#In patients with central serous chorioretinopathy, both intravitreal bevacizumab injections and intravitreal aflibercept injections are effective treatment methods. There were no differences between the two medicines in terms of functional and anatomical recovery, or the injection number and treatment duration.
