Murakawa S, et al. - Researchers examined 27 eyes of 25 patients (18 men, 7 women; average age 71.0 years) with a choroidal neovascularization (CNV) by optical coherence tomography angiographic (OCTA) in order to assess how averaging five en face OCTA images affects the quality of the images in eyes with a CNV. They recorded a 3 × 3-mm image including the CNV that was automatically segmented between the retinal outer layers. A single image (S-image) and the average of five single images of the same area (A-images) were analyzed. Observations revealed that the A-images of a CNV had better quality and there was an absence of a significant difference in the vascular density. The removal of the same signal levels of the noise component and blood vessels may explain the improvement.
