Abstract:
Retinal artery macroaneurysm (RAM) is an acquired retinal arteriole dilatation with vision-threatening complications. Diagnosis of this condition can be made clinically, supported by multi-modal imaging modalities, commonly optical coherence tomography (OCT) and dye-based angiography studies which show the lesion itself and the complications to the adjacent retina. We report a case of an 83-year-old patient with renal impairment who had the diagnosis and monitoring of RAM done using optical coherence tomography angiography (OCT-A) as an alternative to conventional fluorescein angiography. This case highlighted the use of OCT-A using Cirrus 5000 with AngioPlex (Zeiss, Jena, Germany) as a useful diagnostic and monitoring tool for RAM with its features that enables objective quantification of the disease activity via vessel and perfusion density pre- and post-laser treatment.
