Abstract
To identify factors associated with the recovery of foveal photoreceptor disruption in eyes with an impending macular hole (MH) with vitreomacular traction syndrome after surgery. This study comprised 33 consecutive patients who underwent vitrectomy for Stage 1 impending macular hole with disrupted photoreceptor inner segment/outer segment (IS/OS) layer and were followed up for a minimum of 1 year after surgery. Preoperative optical coherence tomography (OCT) parameters were compared between eyes that achieved complete restoration of the IS/OS layer (Group A) and those that did not (Group B). Postoperative serial changes in best-corrected visual acuity (BCVA) and IS/OS disrupted length were also investigated. Smooth and symmetric foveolar contour was restored in 29 eyes (87.9%). Complete recovery of IS/OS disruption was observed in 11 of 33 cases (33.3%, Group A). Group A exhibited a larger percentage of foveal pseudocysts (54.5% vs. 13.6%, P = 0.033) and a smaller mean aperture size (102.1 ± 182.1 μm vs. 241.5 ± 163.8 μm, P = 0.031) than Group B. Postoperatively, Group A revealed a significantly better visual outcome than Group Be, which was the same as Group B, but with the four eyes that developed a full-thickness macular hole excluded. Restoration of the foveal photoreceptor layer was more likely to occur in eyes with a foveal pseudocyst and smaller aperture size.
