  1. Images were recorded with a 3 × 3 × 3 mm resolution; therefore, the conversion factor from voxel volume to mm3 is 27. There was no significant difference between the bulb volumes before and after normalization (at p ≤ 0.05); however, volumes were correlated with 0.92 for the left and right eyes
