Table 1. The mean distances between the fovea locations labeled by ophthalmologists and those predicted by the automatic prediction model.

Predicted models	x-axis (pixels)	y-axis (pixels)	z-axis (slices)	Overall distancea (µm)
LocBscan-3D (n=51)	12.8±3.7	7.7±1.3	0.7±0.7	170.0±43.0b
LocEN-2D (n=53)	46.8±44.1	34.4±28.8	2.0±3.8	675.9±500.0b

LocBscan-3D: Fovea localization from B-scan OCT image sequence with three-dimensional reconstruction; LocEN-2D: Fovea localization from two-dimensional en-face OCT image; SD: Standard deviation. ^aAccording to the machine's settings, each pixel or slice in the x-, y-, and z-axes corresponds to 12, 4, and 66 µm, respectively. After converting pixels to lengths in each axis, the distance between manual depiction and automatic detection was calculated accordingly. The overall distance represents the of each case. ^bP<0.01 for the mean distance between the two models.
