RESUMO
BACKGROUND AND OBJECTIVE: To demonstrate the advantage of optical coherence tomography angiography (OCTA) for the diagnosis and management of proliferative macular telangiectasia type 2 (MacTel2) masquerading as neovascular age-related macular degeneration (AMD). PATIENTS AND METHODS: This is an observational cases series. Three patients referred with the diagnosis of neovascular AMD were identified in this retrospective study. In addition to color fundus, fluorescein angiography, and spectral-domain OCT (SD-OCT) imaging, SD-OCTA (AngioPlex; Carl Zeiss Meditec, Dublin, CA) was performed. RESULTS: SD-OCTA revealed bilateral parafoveal retinal microvascular changes in three patients and unambiguously confirmed the diagnosis of MacTel2. CONCLUSION: OCTA is an important tool for the correct diagnosis of MacTel2 in older patients with the concomitant or masquerading diagnosis of AMD.
