Fig. 1. Binary processing of the fovea and Analysis of the foveal surface symmetry difference (FSSD). (A, F) Single horizontal optical coherence tomography scan through the fovea and foveal cutout (centered on the supposed fovea position) was obtained for analysis. (B, G) Magnified image of previous foveal cutout. (C, H) Foveal cutout was converted into binary image and automated threshold detection was done. (D, I) Flip a previous image horizontally. (E, J) Previous two images were combined with image calculator and half of the gray colored area was measured for FSSD. (A-E) were preoperative images. (F-J) were postoperative 1 month images.
