| Sumario: | Spyridon Dimopoulos, Martin Alexander Leitritz, Focke Ziemssen, Bogomil Voykov, Karl Ulrich Bartz-Schmidt, Faik Gelisken Centre for Ophthalmology, Eberhard-Karls University, Tuebingen, Germany Purpose: To report the visual and morphological outcomes following intravitreal bevacizumab in neovascular age-related macular degeneration (nAMD) with submacular, predominantly hemorrhagic, lesions.Methods: Retrospective study of patients with a follow-up after 1 year. All eyes with submacular hemorrhages larger than 50% of the total lesion size and received only anti-VEGF (vascular endothelial growth factor) monotherapy (intravitreous administration of 1.25 mg bevacizumab, PRN). The primary endpoint was the change in hemorrhage size and time to resolution, in association with the mean best-corrected visual acuity (BCVA). The eyes were grouped based on the size of the hemorrhage: group A (≥1 to <4 disc area [DA]), group B (≥4 to <9 DA), and group C (≥9 DA).Results: Forty-six consecutive eyes were included. The mean area of the hemorrhage was 6 DA at baseline. Eyes with smaller bleeding (group A) had better chances of stabilized or improved vision. Complete resolution of the hemorrhage was seen in 96% of the eyes within 1 year. The mean BCVA increased from 0.81 logarithm of the minimum angle of resolution (logMAR) (95% confidence interval [CI]: 0.70–0.92) (Snellen 20/125) at baseline to 0.75 logMAR (95% CI: 0.62–0.88) (20/125) after 1 year (P=0.11). BCVA improved (one or more ETDRS [Early Treatment of Diabetic Retinopathy Study] lines) in 57% of the eyes (13/23) in group A; 53% (8/15) in group B; and 38% (3/8) in group C.Conclusion: Many of the eyes with hemorrhagic lesions showed stabilization or improvement of the mean BCVA after treatment within 1 year. Anti-VEGF treatment can be considered as a useful treatment option in eyes with hemorrhages secondary to nAMD. Keywords: age-related macular degeneration, bevacizumab, submacular hemorrhage |
