Long-term outcome of highly myopic foveoschisis treated by vitrectomy with or without gas tamponade.

Aim: To evaluate the long-term safety and efficacy of vitrectomy and internal limiting membrane (ILM) peeling with or without gas tamponade for highly myopic foveoschisis.

Methods: We performed an open-label, observer-blinded clinical trial of 85 patients with myopic foveoschisis between 2000 and 2012. Patients were randomly allocated to one of two groups, those who received vitrectomy and ILM peeling without gas tamponade (no-gas group) or those who with gas tamponade (gas group) and follow up at least 5y.
