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.
