| Sumario: | Kazuyuki Kumagai,1 Nobuchika Ogino,2 Marie Fukami,1 Mariko Furukawa1 1Kami-iida Daiichi General Hospital, Nagoya, Aichi, Japan; 2Shinjo Ophthalmologic Institute, Miyazaki, Japan Purpose: The purpose of this study was to determine the long-term outcomes of intravitreal bevacizumab (IVB) or intravitreal tissue plasminogen activator (tPA) or vitrectomy for macular edema associated with a branch retinal vein occlusion (BRVO).Methods: This was a retrospective, interventional case series. Forty-one patients received a single 1.25 mg of IVB injection and followed by pro re nata protocol, 71 patients received a single intravitreal tPA, and 116 patients underwent phacovitrectomy with intraocular lens implantation.Results: The baseline characteristics and follow-up periods were not significantly different among the three groups. The mean follow-up period was 55.5 months with a range of 12–160 months. Sixteen patients (39.0%) in the IVB group, 24 patients (33.8%) in the tPA group, and two patients (1.7%) in the vitrectomy group underwent additional surgeries during the follow-up period. The best-corrected visual acuity (BCVA) significantly improved in all groups at 1 year after the initial treatment (all, P<0.0001) and at the final visit (all, P<0.0001). The differences in the BCVA between the three groups were not significant at all times after the initial treatment.Conclusion: The three groups led to similar long-term good visual outcomes. However, additional surgeries were performed in more than 30% of patients in the IVB and tPA groups.
