Vitrectomy without internal limiting membrane peeling for macular retinoschisis and foveal detachment in highly myopic eyes

Purpose: To report the surgical outcome of pars plana vitrectomy (PPV) without internal limiting membrane (ILM) peeling in three highly myopic patients with macular retinoschisis and associated posterior staphyloma. Methods: We report three highly myopic patients with macular retinoschisis and foveal detachment who underwent simple PPV without ILM peeling, with long‐acting gas tamponade. Main outcome evaluations included best corrected visual acuity, biomicroscopic appearance and optical coherence tomography findings. Results: Pars plana vitrectomy without ILM peeling resulted in anatomic and functional improvement in all three operated eyes for follow‐up periods of ≥ 12 months. Conclusions: Pars plana vitrectomy without ILM peeling is effective for treating macular retinoschisis and foveal detachment in highly myopic eyes with posterior staphyloma. Visual and anatomic outcomes are comparable with those in previous studies in which ILM removal was performed.
