Monthly Monthly Monthly Monthly injections sham injection ranibizumab 0.3 mg ranibizumab 0.5 mg In the later stage of PRN ranibizumab treatment, Month 6 Primary endpoint were the vision gains maintained? Crossover PRN PRN PRN In the later stage of PRN ranibizumab treatment, PRN injections ranibizumab 0.5 mg ranibizumab 0.3 mg ranibizumab 0.5 mg what dosing frequency was required to maintain Secondary endpoint Month 12 vision gains and anatomic stability? HORIZON open-label extension PRN ranibizumab 0.5 mg † * BRAVO patients were eligible for laser treatment once during the treatment period and once during the observation period, beginning at months 3 and 9, respectively, if they met the prespecified visual and anatomic criteria. † Patients were monitored at least every 3 months. 3 4 1
