Posterior vitreous detachment and macular hole formation in myopic foveoschisis

PURPOSE: To report two cases of macular hole (MH) associated with myopic foveoschisis (MF). DESIGN: Interventional case report. METHODS: Two women presented with metamorphopsia. Preoperative optical coherence tomography (OCT) showed an MH and MF. We performed vitrectomy, internal limiting membrane (ILM) peeling and gas tamponade. RESULTS: Preoperative OCT examination and intraoperative microscopic observation revealed partial posterior vitreous detachment (PVD) at the posterior retina and vitreous strands adhering to the edge of the MHs. The MF resolved in both patients, but the MHs remained open postoperatively. CONCLUSIONS: Although the contribution of tangential traction cannot be excluded, the mechanism of MH formation in eyes with MF may be anteroposterior traction via abnormal vitreofoveal adhesion resulting from partial PVD.
