Morphologic and functional outcomes of different optical coherence tomography patterns of myopic foveoschisis after vitrectomy and inner limiting membrane peeling

Abstract

Objective: To evaluate the morphologic and functional outcomes of different optical coherence tomography (OCT) patterns of myopic foveoschisis after vitrectomy with Inner Limiting Membrane (ILM) peeling. Methods: In this prospective non-randomised study, 62 consecutive eyes with Myopic Foveoschisis were categorised into three groups according to OCT pattern: retinoschisis type (Rt) Group (23/62), foveal detachment type (FDt) Group (20/62) and macular hole type (MHt) Group (19/62). All patients underwent 25-Gauge vitrectomy and ILM peeling. Air or gas tamponade was used. All patients were observed at month 1, 2, 4 and 6 after surgery. Main outcomes measures: surgical success as resolution of myopic foveoschisis, central retinal thickness (CRT), IS/OS junction recovery and best-corrected visual acuity (BCVA) measurement. Any complication was reported. Results: In all eyes OCT showed a resolution of the retinoschisis, foveal detachment and macular hole pattern, respectively. CRT significantly decreased in all Groups (p < 0.0001), postoperative CRT (R −0.49, p < 0.0001), and the recovery of IS/OS junction at 6 months (R 0.76, p < 0.0001). Few postoperative complications occurred. Conclusions: Vitrectomy with ILM peeling results in favourable anatomic and functional outcomes for different patterns of myopic foveoschisis.
