Change in best corrected Snellen visual acuity (BCVA) and central retinal thickness (CRT) on OCT were the primary outcomes. Automated and manual measurements were made for all OCT characteristics.Results: Seventy-three (100%) and 58 (79.5%) eyes were followed for 3 and 6 months, respectively. The mean BCVA improved from 20/177 to 20/160 (p = 0.03) at 3 months and to 20/143 (p = 0.04) at 6 months. The mean CRT decreased 93 µm (p<0.0001) and 105 µm (p<0.0001) at 3 and 6 months, respectively. Baseline BCVA worse than 20/100 was associated with greater visual improvement (p⩽0.04). Eyes with baseline CRT greater than 400 µm experienced a greater mean CRT reduction (p<0.05). Treatment-naïve patients had a greater mean CRT reduction than those previously treated with any modality (p<0.05)Conclusions: Baseline BCVA and CRT positively influence mean visual and CRT improvement, respectively, after intravitreal bevacizumab in wet AMD. Any prior treatment predicted less CRT reduction.
