Summary

High myopic schisis (HMF) has the clinical feature of separation between retinal layers. It is sometimes accompanied with foveal retinal detachment, macular lamellar hole, epiretinal membrane and vitreous retraction. HMF may develop to macular hole, macular detachment and will damage the visual function. Pars plana vitrectomy (PPV) is a commonly used surgery in the treatment of HMF. PPV together with internal limiting membrane (ILM) peeling and long-term gas tamponade was reported to be safe and effective. But nowadays there was no available long-term gas in our country. Also, whether ILM peeling is necessary remains controversial, Indole cyanine green (ICG)was proved to have potential toxicity to the retina and the ILM peeling has the risk of causing secondary macular hole. We propose to make a prospective nonrandomized controlled study to evaluate the safety and efficiency of using PPV alone in the treatment of HMF.
