Abstract

NUNES, Renata Portella et al. Effectiveness of monthly and fortnightly anti-VEGF treatments for age-related macular degeneration. Arq. Bras. Oftalmol. [online]. 2019, vol.82, n.3, pp.225-232.  Epub Feb 25, 2019. ISSN 0004-2749.  http://dx.doi.org/10.5935/0004-2749.20190043.

Purpose:

To study the efficacy and safety of treatments with ranibizumab and bevacizumab for exudative age-related macular degeneration.

Methods:

A parallel randomized clinical trial was conducted to compare the efficacy and safety of three regimens (bevacizumab every month, bevacizumab every 2 weeks, and ranibizumab every month), followed by as-needed retreatments, for 1 year, in previously untreated individuals with age-related macular degeneration. The primary outcome was change in visual acuity and in central macular thickness after 1 year of follow-up. Subjects were assigned randomly to one of the three groups in a 1:1:1 ratio, and investigators and examiners were blinded to the randomization results.

Results:

We included 15 patients in each group. After 1 year of follow-up, we found statistically significant improvements in visual acuity and central macular thickness reduction in all groups. However, we found no statistically significant differences between the three groups.

Conclusions:

The bi-weekly follow-up was effective and we found no significant differences in efficacy or safety between the treatments with ranibizumab and bevacizumab.
