Time course of OCT findings in representative patients whose RRD were present within the vascular arcade but did not involve the fovea.
Left panel: A, the preoperative fundus Images of the left eye of a 62-year-old man. The subfoveal OCT findings were normal during the follow-up period (B: Pre, C: 1 months, D: 3 months, E: 6 months, F: 12 months after the surgery, respectively). M-score was normal during the follow-up period. Right Panel: G, the preoperative fundus Images of the left eye of a 62-year-old man. The subfoveal OCT findings were normal during the follow-up period (H: Pre, I: 1 months, J: 3 months, K: 6 months, L: 12 months after the surgery, respectively). Preoperative M-score was normal, but vertical and horizontal M-score were 0.4 and 0.3 after 12months surgery, respectively.

Changes in visual functions of patients after RRD surgery.
In all cases, the average metamorphopsia score at 3, 6, and 12 months postoperatively significantly improved from the score at 1 month (p< 0.01) (A). The average metamorphopsia score at 3, 6, and 12 months postoperatively significantly improved from the score at 1 month in Group C (p< 0.01) (C). The average metamorphopsia score did not change throughout the follow-up period in Groups A and B (C). In all cases, BCVA (logMAR) at 1, 3, 6, and 12 months postoperatively significantly improved compared with preoperative BCVA (P < 0.01) (B). BCVA (logMAR) at 1, 3, 6, and 12 months postoperatively significantly improved compared with preoperative BCVA in Group C (P < 0.01) (D). BCVA (logMAR) did not change throughout the follow-up period in Groups A and B (D).
