- Abstract
Objective: Type 2 idiopathic macular telangiectasia (MacTel2) is a rare retinal disease that has still not been well-defined. The aim of the present manuscript is to describe the clinical features by multimodal retinal imaging, to present the functional characteristics, and to estimate the prevalence of the disease., Methods: A retrospective study was conducted on the 12 eyes of 6 patients with MacTel2. Fundus colour photographs, fundus autofluorescence, fluorescein angiography, optical coherence tomography (OCT), and OCT-angiography were performed and subsequently analysed. Visual acuity (VA) was prospectively recorded. The prevalence was established based on the patients referred to a specialised macular diseases unit. Minimum follow-up period was 18 months., Results: Prevalence of MacTel 2 in our study was 0.12%. Clinical features were presented using multimodal retinal imaging. VA remained stable during follow-up. Three patients developed choroidal neovascularisation (CNV), requiring intravitreal treatment with antiangiogenic agents., Conclusions: The prevalence of the disease found was 0.12%. The study using multimodal imaging allows a more accurate diagnosis and follow-up of this pathology. The VA is maintained during the 18-month follow-up (P=.492). Patients who develop CNV and are treated with antiangiogenic agents appear to respond adequately to them. More studies are needed to establish these conclusions., (Copyright © 2017 Sociedad Española de Oftalmología. Publicado por Elsevier España, S.L.U. All rights reserved.)
