Comparison of macular neovascularization lesion size by the use of spectral‐domain optical coherence tomography angiography and swept‐source optical coherence tomography angiography vs indocyanine green angiography
Acta Ophthalmologica Aug 28, 2020
Haas AM, Ahmed D, Stattin M, et al. - In this prospective, observational case series, researchers contrasted the lesion sizes of macular neovascularization (MNV) imaged with spectral‐domain (SD) and swept‐source (SS) optical coherence tomography angiography (OCTA) as well as indocyanine green angiography (ICGA). Patients presenting a secured diagnosis of MNV on ICGA or Fluorescein Angiography were imaged by SD‐OCTA and SS‐OCTA on the same day. Twenty eyes from 20 patients (11 females, 55%) have been enlisted. According to findings, SD‐OCTA tends to display smaller areas of MNV extension compared with SS‐OCTA for 6 × 6 mm2 scans. MNV's lesion size can be contrasted very well between the different devices, stressing the use of OCTA for monitoring neovascular area. Lesion measurements on SS‐OCTA are better correlated with ICGA than SD‐OCTA.
