Intravitreal Anti-Vascular Endothelial Growth Factor for Macular Edema due to Complex Retinal Arterial Macroaneurysms

Introduction: Complex retinal arterial macroaneurysms (RAM) are often accompanied by hemorrhage and/or affect the macula. We evaluated the effect of intravitreal anti-vascular endothelial growth factor (anti-VEGF) therapy using ranibizumab or aflibercept with or without laser photocoagulation in the treatment of macular edema due to RAM. Methods: A case report of two patients with secondary macular edema caused by RAM is presented. The first case was a 76-year-old female treated with two 0.5-mg injections of ranibizumab and additional focal laser photocoagulation. This patient presented a solely intraretinal exudation. The second patient was a 96-year-old female, who received one 2.0-mg injection of aflibercept. She showed sub- and intraretinal edema. We documented the clinical courses of these patients based on fundus photography, fluorescein angiography, and spectral-domain optical coherence tomography. Patients were followed-up for 12 months. Results: Patients were treated successfully using anti-VEGF therapy (ranibizumab or aflibercept) with or without laser photocoagulation. In both cases, we observed a complete regression of the macular edema and an increase in visual acuity. Conclusion: RAM can manifest with heterogeneous findings. Intravitreal anti-VEGF therapy with or without laser photocoagulation may be an effective treatment option in cases of macular edema due to RAM. Aflibercept and ranibizumab seem to be a potent anti-VEGF therapy for RAM. Individualized patient care is needed.
