Parrulli S, Corvi F, Cozzi M, et al. - In the present study, the researchers sought to compare fluorescein angiography (FA) and five different optical coherence tomography angiography (OCTA) devices and to evaluate their reproducibility in the assessment of retinal microaneurysms (MAs) secondary to diabetic retinopathy (DR). Twenty eyes of 15 patients with DR have been included. Findings suggested that FA remains the best imaging modality for visualizing retinal MAs. Compared with other devices, spectralis OCTA was able to detect more MAs, possibly due to the higher number of B-scans in the scanned area as well as the higher number of repeated B-scans. As in clinical practice, high variability between OCTA devices should be taken into account in future clinical trials.
