ABSTRACT

PURPOSE:

To evaluate the short-term efficacy of intravitreal triamcinolone (IVTA) injection for the treatment of macular edema secondary to branch retinal vein occlusion (BRVO) refractory to intravitreal bevacizumab injections.

METHODS:

This retrospective, observational study included 23 eyes of 23 patients with macular edema secondary to BRVO. The patients with macular edema unresponsive to 2 or more consecutive monthly intravitreal bevacizumab injections were treated with IVTA. Best-corrected visual acuity (BCVA) and central foveal thickness (CFT) based on optical coherence tomography were evaluated before IVTA and 1 month and 3 months after IVTA injections.

RESULTS:

All patients were previously treated with 3.4 ± 1.2 intravitreal bevacizumab injections. The IVTA injection was performed at 4.3 ± 1.7 weeks after the last bevacizumab injection. The logarithm of the minimal angle of resolution (log MAR) BCVA was also decreased from 0.61 ± 0.45 to 0.52 ± 0.35 after 1 month and to 0.58 ± 0.37 after 3 months of IVTA, although without statistical significance (p = 0.114 and 0.412, respectively). Eight eyes (34.8%) showed more than 3 lines improvement of BCVA and 4 eyes (17.4%) showed stable BCVA increasing 2 lines or less. CFT was significantly improved from 512 ± 166 µm to 310 ± 139 µm after 1 month and to 324 ± 159 µm after 3 months of IVTA injections (p = 0.014 and 0.031, respectively).

CONCLUSIONS:

IVTA was beneficial in some patients with macular edema secondary to BRVO refractory to intravitreal bevacizumab therapy. This study indicates that IVTA could be considered as a treatment option for refractory macular edema associated with BRVO.
