Surgical outcomes of macular buckling techniques for macular retinoschisis in highly myopic eyes

Purpose: To report the anatomic and visual results following macular buckling for patients with macular retinoschisis related to high myopia. Methods: Thirty-nine highly myopic eyes (mean refractive error -16.7. D; range, -9 to -24. D) of 36 patients (mean age 59. years; range, 35-79. years) presenting with macular retinoschisis associated with a posterior staphyloma, who underwent combined vitrectomy and macular buckling were evaluated. Main outcome measures included best-corrected visual acuity (BCVA) and optical coherence tomography (OCT) findings. Three cases were excluded due to short follow-up (less than 3. months). The mean follow-up was 16. months. Results: The mean BCVA increased from 0.76 to 0.43. LogMAR (p= 0.001). Visual acuity improved in 30. eyes (83.3%), remained stable in three eyes (8.3%) and decreased in three eyes (8.3%). OCT showed resolution of foveoschisis with foveal reattachment in all eyes. None of the evaluated patients developed a macular hole during follow-up. Conclusion: Macular buckling associated with vitrectomy results in good anatomic and visual outcomes in patients with myopic foveoschisis.
