SAN FRANCISCO – The results of the second year of the Comparison of Age-related macular degeneration Treatment Trials (CATT) indicate that bevacizumab (Avastin®) is equivalent to ranibizumab (Lucentis®) in the treatment of wet age-related macular degeneration (AMD) through two years when using similar dosing regimens. The study also showed that monthly dosing produced slightly more vision gain than an as-needed regimen. The final visual results, however, were similar in all treatment groups, regardless of dosing frequency, with 60 percent or more of the patients achieving driving vision (20/40 vision or better).
