The effectiveness and safety of posterior scleral reinforcement with vitrectomy for myopic foveoschisis treatment: a systematic review and meta-analysis.

PSR combined with vitrectomy helps improve 80% MF patients' BCVA; the average benefit on BCVA is - 0.46 logMAR unit. The average change in AL is - 1.74 mm; patients with AL ≥ 30 mm benefit much more than the patients with AL < 30 mm. The retinal reattachment rate is up to 93%; the MH closure rate is 65%. About 9% patients will suffer from extrusion, choroidal atrophy, choroidal neovascularization, and other complications. The outcomes were not influenced by presence of MH, disease recurrence, or ILM peeling.
