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 Mar 21, 2021
Haas AM, Ahmed D, Stattin M, et al. - In this prospective, observational case series, researchers compared 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). On the same day, patients with a confirmed diagnosis of MNV on ICGA or Fluorescein Angiography were imaged by SDOCTA and SS‐OCTA. Twenty eyes from 20 patients (11 females, 55%) were included in the study. SD‐OCTA appears to display smaller areas of MNV extension than SS‐OCTA regarding 6 × 6 mm 2 scans. The lesion size of MNV can be easily compared between the different devices, highlighting the importance of OCTA for monitoring neovascular area. SS‐OCTA lesion measurements correlate better with ICGA than SD‐OCTA.
