"The OCT images, fundus fluorescein angiography (FFA) images, and best-corrected visual acuity (BCVA) of baseline and 12 weeks after laser treatment were all from the ClinicalTrials.gov registered clinical trial (NCT02735213). OCT images were from the examinations of spectral-domain optical coherence tomography (SD-OCT) (Spectralis; Heidelberg Engineering, Heidelberg, Germany), including 9-mm horizontal and vertical B-scan of macular with and without enhanced depth imaging (EDI) technology, volume mode (25-line consecutive scans, 20° × 20°, 5.8 × 5.8 mm) of the macula, and dense volume mode of leakage points. Leakage location and the number of leakage points of baseline were measured by FFA images (Spectralis, Heidelberg Engineering, Heidelberg, Germany). BCVA was in the form of ETDRS letters."
