Purpose : Branch retinal vein occlusion (BRVO) is a retinal vascular disease associated with macular edema (ME) and consequential vision loss. In the past, a ‘watchful waiting’ approach has been advocated in early stage BRVO to allow for possible spontaneous resolution of ME. However, data from the BRAVO study suggest that delaying treatment with anti-vascular endothelial growth factor (VEGF) in BRVO may limit visual acuity (VA) gains. Here we present an exploratory analysis from the 24-month BRIGHTER study on the impact of disease duration and baseline VA in BRVO patients treated with ranibizumab with or without laser, or with laser alone.

Methods : BRIGHTER (NCT01599650) was a 24-month, phase IIIb, open-label, randomized, active-controlled, three-arm multi-center study that enrolled 455 patients with BRVO across 81 sites in Europe, Australia and Canada.

Results : 1) Irrespective of baseline VA and duration, ranibizumab treatment (with or without laser) of all BRVO patients resulted in a significant increase in VA over 24 months (fig.1).
2) Patients with high baseline VA (≥60 letters) achieved significant VA gains (mean best corrected VA change [BCVA] of +12.1 and +11.8 letters, respectively) with ranibizumab treatment (with or without laser) compared with those treated with laser alone (mean BCVA change of +3.3 letters).
3) For patients with low baseline vision (≤39 letters), treatment with ranibizumab resulted in a greater letter gain (+23.2 letters) than patients with high baseline vision; however, high baseline vision patients achieved better absolute vision at study end (79.4 vs 56.8 letters for highest vs lowest baseline VA, respectively).
4) For patients with a short disease duration (<12 months), ranibizumab treatment resulted in a mean BCVA gain of 17.3 letters, while patients with a longer disease duration (≥12 months) had a mean BCVA gain of 8.4 letters (fig. 2).
5) For patients with a shorter disease duration (<12 months), ranibizumab monotherapy resulted in a gain of ≥15 letters in a shorter time (85 days) compared with patients treated with ranibizumab plus laser (118 days) or laser alone (266 days).

Conclusions : These results show that ranibizumab intervention earlier, and in those with a higher VA, provides better VA outcomes over 24 months than with laser. Delaying treatment may have a significant negative impact on patient quality of life.
