Misalignment of foveal pit and foveal bulge determined by ultrahigh-resolution SD-OCT in normal eyes

The foveal bulge (FB) results from a lengthening of the outer segments of the photoreceptors which then makes the central fovea arcuate in shape. The purpose of this study was to evaluate the morphological features and locations of the FB relative to the foveal pit (FP) in a single B-scan image. One hundred and forty-seven eyes of 147 healthy volunteers were studied. Horizontal and vertical B-scan optical coherence tomographic (OCT) images...
