Abstract BACKGROUND: We evaluated the effect of intravitreal anti-vascular endothelial growth factor therapy using bevacizumab or ranibizumab for retinal macroaneurysms with macular exudation. METHODS: In a retrospective interventional case series patients with retinal macroaneurysms were treated with either 1.25 mg intravitreal bevacizumab or 0.5 mg ranibizumab as first-line therapy. Patients were imaged by fluorescein angiography and optical coherence tomography. Retreatment was performed in case of persistent intraretinal or subretinal fluid in optical coherence tomography. RESULTS: Ten patients (10 eyes) with macroaneurysm involving the macula were treated with an average of 3.0 intravitreal anti-vascular endothelial growth factor injections. Mean best corrected visual acuity of all patients improved by 17 letters from baseline to the last follow-up visit. In 7 out of 10 patients, the fovea was affected by a secondary edema. In cases with foveal involvement, central retinal thickness decreased from 366 µm at baseline to 266 µm at the last follow-up visit. In the course of treatment 8 out of 10 patients showed evidence of marked regression of macular exsudation. CONCLUSION: Intravitreal anti-vascular endothelial growth factor therapy appears to be a promising treatment alternative to laser treatment in cases of retinal macroaneurysms with macular exudation.
