PURPOSE: To assess the sequence of anatomical resolution of myopic foveoschisis (MFS) after vitrectomy.

DESIGN: Monocentric retrospective observational case series.

SUBJECTS: The files of consecutive patients with MFS who underwent vitreoretinal surgery and were followed postoperatively for at least 6 months were reviewed.

METHODS: Patients underwent pars plana vitrectomy for MFS. The central foveal thickness (CFT) was measured. The presence of a foveal involvement, and/or outer retinoschisis (ORS), with or without inner retinoschisis (IRS), and foveal detachment (FD) were analyzed. Anatomical success was defined as the resolution of foveal ORS and FD.

MAIN OUTCOME MEASURES: The main outcome was the time to resolution of the different morphologic features of MFS after surgery.

RESULTS: Thirty-nine eyes of 36 patients were included in the analysis. The mean follow-up was 14.8 ± 12.9 months (range, 6-84 months). Anatomical success was achieved in 82% of cases at the end of the follow-up and in > 80% of cases during the first year. The CFT was significantly decreased in 79% of cases at 3 months. Inner retinoschisis, present in 18 eyes (46%), resolved in all cases after a median time of 1 month. Foveal ORS, present in all cases, resolved in 82% of cases after a median time of 3 months. The FD, present in 23 eyes (59%), resolved in 91% of cases after a median time of 6 months. Extrafoveal ORS resolved in 59% of cases after a median time of 12 months. The mean best-corrected visual acuity significantly improved from 0.80 ± 0.64 logarithm of the minimum angle of resolution (logMAR) (Snellen Eq 20/148) to 0.48 ± 0.52 logMAR (Snellen Eq 20/70).

CONCLUSIONS: Most MFS (80%) are completely resolved during the first year. The decrease in CFT and early resolution of IRS could be used as early biomarkers of surgical success.
