Vitrectomy and internal limiting membrane peeling without gas tamponade for myopic foveoschisis.

Purpose: To evaluate the efficacy of vitrectomy including internal limiting membrane (ILM) peeling without gas tamponade for myopic foveoschisis (MF).

Method: In this retrospective study, 15 eyes of 13 consecutive patients with MF underwent pars plana vitrectomy and ILM peeling without gas tamponade. The main outcomes were measured using best-corrected visual acuity (BCVA) and central macular thickness (CMT) on optical coherence tomography (OCT).

Result: The mean refractive error was -11.0 ± 8.2 diopters and mean axial length was 30.8 ± 2.6 mm. The mean BCVA increased from 0.78 ± 0.53 to 0.61 ± 0.75 logMAR unit (p = 0.05), and the mean CMT decreased from 405 ± 143 μm to 255 ± 47 μm (p = 0.002) during a follow-up of 11.8 months. OCT showed a complete resolution of the MF, with foveal reattachment in all eyes. Full-thickness macular hole developed in two eyes during follow-up.

Conclusion: ILM peeling without gas tamponade results in favorable anatomical and visual outcomes.
