Purpose:
To determine the morphological and physiological outcomes and safety of vitrectomy with fovea-sparing internal limiting membrane peeling for myopic macular retinoschisis (MRS).
Methods:
Highly myopic eyes (refractive error greater than -8.0 diopters or an axial length longer than 26.5 mm) with MRS that underwent vitrectomy with fovea-sparing internal limiting membrane peeling were analyzed retrospectively. The best-corrected visual acuity, retinal morphology, and the central and paracentral retinal sensitivities at 2°/6° by microperimetry were evaluated before and after the surgery. Postoperative microscotomas were also determined.
Results:
Thirty-three eyes with MRS; 16 eyes with and 17 eyes without a foveal retinal detachment, were studied. All 33 eyes had an improvement of MRS and foveal retinal detachment partially or completely after surgery, and none developed a full thickness macular hole. The postoperative best-corrected visual acuity, the central retinal sensitivity, and the retinal sensitivity at 2° were significantly better than the preoperative values. Sixteen eyes developed postoperative microscotomas at paracentral 2° and/or 6°.
Conclusion:
The results showed that vitrectomy with fovea-sparing internal limiting membrane peeling is an effective and safe method to treat an MRS regardless of the presence of a foveal retinal detachment. However, careful follow-up should be performed to detect postoperative microscotomas.
