Purpose:
To compare the visual and anatomic outcomes of pars plana vitrectomy between myopic maculoschisis with and without macular detachment (MD).
Methods:
This retrospective comparative study included 38 eyes of 38 patients who received pars plana vitrectomy for myopic maculoschisis between July 2021 and July 2022. Two groups were identified based on whether preoperative MD was detected via optical coherence tomography: 16 eyes with MD and 22 eyes without MD. Surgical effects were assessed by the final best-corrected visual acuity, ellipsoid zone (EZ) state, and the rate of complete fovea relief.
Results:
The postoperative follow-up was 15.25 ± 3.70 and 15.55 ± 3.39 months in the groups with and without MD, respectively ( P = 0.800). The preoperative logarithm of the minimal angle of resolution best-corrected visual acuity was 1.21 ± 0.65 and 0.55 ± 0.37 in the groups with and without MD, respectively ( P = 0.001). Nevertheless, no difference existed in the postoperative best-corrected visual acuity at final visit between the groups with and without MD (0.51 ± 0.29 logarithm of the minimal angle of resolution, ∼20/64 VS . 0.40 ± 0.41 logarithm of the minimal angle of resolution, ∼20/50, P = 0.345). During the follow-up period, the rates of EZ band reconstruction were 40.00% (6/15) and 33.33% (2/6) in the groups with and without MD, respectively ( P = 0.590). Finally, a total of 33 eyes achieved complete fovea relief, including 13 eyes (81.25%) in the group with MD and 20 eyes (90.91%) in the group without MD ( P = 0.701).
Conclusion:
In myopic maculoschisis eyes, the presence of MD did not significantly affect postoperative visual or anatomical outcomes in our cohort.
