Minimal Gas Vitrectomy and As-Needed Positioning Duration for Idiopathic Macular Holes.

ABSTRACT:

Introduction

This study aimed to investigate postoperative outcomes of minimal gas vitrectomy (MGV) combined with a reduced period of gas-fovea contact in the management of idiopathic full-thickness macular holes (MHs).

Methods

This retrospective cohort study included patients who underwent surgery for MHs with minimal hole diameters of 250-800 µm and categorized them into two groups: conventional fluid-gas exchange (FGX) (38 eyes) and MGV (28 eyes), with FGX replaced by a 1.0-1.2 mL injection of pure sulfur hexafluoride after internal limiting membrane peeling. Postoperatively, patients in the MGV group were kept in a face-down position, switching to face-forward or no positioning (pseudophakia) once MH closure was confirmed by optical coherence tomography, performed every
