case_images: (a) Full-thickness macular hole (FTMH) in the right eye before surgery. Hole diameter equal to 475 microm. (b) Unclosed FTMH in the right eye 1 month after vitrectomy. Poor image quality caused by the rest of SF6 gas. Hole diameter equal to 452 microm. (c) Closed FTMH 3 months after secondary vitrectomy in the right eye. (d) Postoperative microperimetric results of the right eye. (e) OCT image of macula of the healthy, left eye. (f) Normal microperimetry result of the left eye. Postoperative FAZ measurement using a nonflow software. Foveal avascular zone (FAZ) of the right eye (g) twice operated, increased significantly compared to FAZ of the healthy, left eye (h).

case_images: Seven months later, secondary vitrectomy was performed and ended with V-shape closure of FTMH (Figure 3). 11 months observation of the right eye showed the macular atrophy and following functional results: BCVA was 0.05, AT in microperimetry was 12.8, fixation was relatively unstable (P1 = 42%, P2 = 85%), and eccentric fixation was found.
