    (2019) Dikel, Nevin; Yumusak, Erhan; Gökçınar, Nesrin
    Objectives: The present study aims to compare the long-term efficacy and safety results of intravitreal ranibizumab (RAN), dexamethasone intravitreal implant (DEX) and intravitreal triamcinolone acetonide (IVTA) injections in macular edema due to branch retinal vein occlusion (BRVO). Methods: In this retrospective study, one eye each of 43 patients who were treated with intravitreal injections for macular edema secondary to BRVO was recruited into one of the study groups: RAN group (n=17), DEX group (n=16) and IVTA group (n=10). All patients were followed-up for 12 months. Best-corrected visual acuity (BCVA), central macular thickness (CMT), subfoveal choroidal thickness (SFCT) and intraocular pressure (IOP) at month 1, 3, 6, and 12 were compared with baseline. Results: The BCVA increased significantly in the RAN and DEX groups at all visits (all p<0.05). BCVA increase in the IVTA group was significant only at month 1 and 6. CMT decreased significantly in all groups at the end of one year of follow-up (p=0.007; p=0.001; p=0.044, respectively). SFCT significantly decreased in all groups at month 1 (all p<0.05). IOP significantly increased in none, 18.8%, 30% of the patients in the RAN, DEX and IVTA groups, respectively. Cataract surgery was performed in none of the patients, 6.3%, and 30% of the patients in the RAN, DEX, and IVTA groups, respectively. Conclusion: BCVA increase was more prominent in both of the RAN and DEX groups than in the IVTA group. DEX may decrease the injection burden; however, ranibizumab may be a safer choice.
