Dark Halo and MNV: a Study Between ICGA and OCTA
Dark Halo a New Biomarker in Macular Neovascularization: a Comparative Study Between ICGA and OCTA
Study Overview
Status
Conditions
Detailed Description
Dark halo is defined as a dark perilesional of flow decrease due to an area of reduced choroidal flow adjacent to the macular neovascularization (MNV).
The detection of MNV vascular details was only possible through invasive dye injection, such as fluorescein angiography (FA) or indocyanine green angiography (ICGA).
Optical coherence tomography angiography (OCTA) is a recent imaging technique that is able to detect the perfusion and non-perfusion areas carefully.
The aim of study is to compare the evaluation of dark halo area of MNV between ICGA and OCTA
