Fig. 1From: Peripapillary vessel density correlates with visual field mean sensitivity in highly myopic eyesOptic disc boundary in optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA). A The boundary of the optic disc was labelled automatically. B The boundary of the optic disc was then manually delineated, and the center of the optic disc was determined by automatically finding the best ellipse fit of the optic disc boundaryBack to article page
