Abstract: AIM: To compare visual acuity and central macular thickness (CMT) changes in neovascular age related macular degeneration patients treated with either 6 weekly bevacizumab regimen or 4 weekly ranibizumab on an as required basis. METHODS: Patients made an informed choice between bevacizumab 1.25 mg or ranibizumab 0.5 mg. The selected treatment was administered in the first 3 visits. Bevacizumab patients were followed-up 6 weekly and ranibizumab 4 weekly. Retreatment criteria was based on the reduction of >5 letters in the best-corrected visual acuity (BCVA), the presence of retinal fluid on optical coherence tomography (OCT) or new retinal haemorrhage. RESULTS: Visual acuity at 2y bevacizumab patients gained 7.0 letters and ranibizumab 9.2 (P=0.31, 95% CI -6.4 to 2.0). At 2y 86% of bevacizumab and 94% ranibizumab patients had not lost 15 letters or more (P=0.13). Mean CMT decreased at 2y bevacizumab by 146 ?m, ranibizumab 160 ?m (P=0.72). Mean number of injections was at 2y bevacizumzb 11.9, ranibizumab 10.3 (P=0.023). CONCLUSION: Bevacizumab 6 weekly on an as required basis was not demonstrably non-inferior to ranibizumab 4 weekly pro re nata (prn) in terms of BCVA and change in CMT. In the bevacizumab group, one more injection was required in the second year compared to the ranibizumab group.
