Multimodal imaging in retinal artery macroaneurysms

Abstract

AbstractPurposeTo describe multimodal imaging features in eyes with retinal artery macroaneurysms (RAM).MethodsA retrospective case series of 4 eyes diagnosed with RAM. All patients underwent a detailed ophthalmic examination, fundus photography, fluorescein angiography, swept source optical coherence tomography (SS‐OCT) and swept source optical coherence tomography angiography (SS‐OCTA).ResultsAll patients were females with a mean age of 57‐year‐old. There was a history of systemic hypertension in 3 patients. An acute vision loss was reported in 2 cases. The best corrected visual acuity at presentation ranged between +1.7 and +0.1 LogMar. RAM was single and unilateral in all cases. The RAM were seen in the temporal half of the retina in all cases and were localized in the superior temporal arcade in 2 cases and in the inferior temporal arcade in 2 cases. Fluorescein angiography allowed for the visualization of the RAM in 3 cases. SS‐OCT visualized the RAM in all cases and their consequences on the surrounding area and on the macula. SS‐OCTA allowed observation of blood flow in each layer of the RAM. En face OCT permitted delineation of the macroaneurysm wall in 2 cases.ConclusionsRetinal artery macroaneurysm is an acquired rare vascular disease that may mimic a variety of other conditions. Multimodal imaging approach is very useful for planning and assessing therapy.
