The sequential retinal surface maps and the OCTA images showing the FAZ in the superficial and deep plexuses at each time are shown in Figure 1.
Postoperative decrease of the FAZ area in the superficial plexus can be fit by a hyperbolic function of y=0.336-0.138*x/(1.634+x).. Note:
R2=0.993.. Abbreviation: FAZ, foveal avascular zone.

Analyses of the changes in the superficial plexuses showed that the postoperative decrease of the FAZ area can be fit by a hyperbolic curve (Figure 2; R2=0.993).
The retinal surface map (top left), optical coherence tomography angiography images showing foveal avascular zone in the superficial and deep plexuses (top right), and horizontal cross-sectional swept-source optical coherence tomography image (bottom) of the normal fellow eye.

The OCTA images of the superficial and deep plexuses and the horizontal cross-sectional SS-OCT image of the normal fellow eye are shown in Figure 3.
The horizontal cross-sectional swept-source optical coherence tomography images at each visit.. Note: Preoperative image with a thin epiretinal membrane is shown at the top, then the images 1 day, 2 days, 9 days, and 37 days after the surgery are shown sequentially to the bottom.

The sequential horizontal cross-sectional SS-OCT images during the follow-up period are shown in Figure 4.
The preoperative and the day 37 postoperative layer-by-layer retinal thicknesses in the horizontal (top) and vertical lines (bottom) at 500 mum from the foveal center.. Notes: The measurements on temporal, nasal, superior, and inferior points are shown.. Abbreviations: GCIPL, ganglion cell-inner plexiform layer; INL, inner nuclear layer; ONL, outer nuclear layer; OPL, outer plexiform layer; RNFL, retinal nerve fiber layer.

The thicknesses of the different retinal layers preop-eratively and at day 37 postoperatively determined by the horizontal (top) and vertical lines (bottom) at 500 mum from the foveal center are shown in Figure 5.
