Abstract

PURPOSE:

To evaluate the anatomic and functional results of the treatment with intravitreal bevacizumab in complicated retinal arterial macroaneurysm (RAM).

DESIGN:

A multicenter interventional, prospective, nonrandomized study.

METHODS:

Thirty-eight macroaneurysms of 37 patients with foveal complications were evaluated. All patients underwent a comprehensive ophthalmologic examination, fluorescein angiography (FA), and spectral-domain optical coherence tomography (SD OCT) examination. Each patient underwent 3 monthly injections of bevacizumab 1.25 mg/0.05 mL; 3 follow-up visits were planned at week 2, 6, and 12.

RESULTS:

Both best-corrected visual acuity (BCVA), expressed in logarithm of minimal angle of resolution (logMAR), and central retinal thickness (CRT) significantly improved during the follow-up visits (0.57 ± 0.21 vs 0.41 ± 0.15 vs 0.23 ± 0.13 vs 0.09 ± 0.10 and 520.38 ± 191.05 vs 396.24 ± 136.18 vs 283.86 ± 71.87 vs 214.84 ± 26.86, respectively, Friedman test P < .0001 for all variables). At 6 weeks of follow-up, FA showed complete closure of the RAM in 36 of 38 cases (94.7%). Four weeks following the third injection, the macular edema had completely resolved and hard exudates regressed slowly in 100% of patients.

CONCLUSIONS:

Intravitreal bevacizumab is an effective therapy for complicated RAM, quickly improving BCVA and CRT. Anti-vascular endothelial growth factor (VEGF) drugs might actively close the involved pathologically permeabilized retinal artery and normalize the vessel wall formation by localized inhibition of VEGF.
