Purpose To investigate the correlation between postoperative metamorphopsia and macular deformation after macular hole (MH) surgery. Methods This study included 28 eyes of 28 patients who underwent vitrectomy and internal limiting membrane (ILM) removal for idiopathic MH. The retinal vasculatures were compared between preoperative and postoperative photographs, and postoperative deformation of the macula was assessed as deformation of the square grid. The displacement of each node was measured, ...

Purpose To compare bleb vascularity changes using optical coherence tomography angiography (OCT-A) between mitomycin-C (MMC)-augmented trabeculectomy and phacotrabeculectomy and to determine whether bleb vascularity measurements during preoperative and early postoperative periods could act as surrogate parameters to predict surgical outcomes.

BACKGROUND AND OBJECTIVE: To investigate the displacement of foveal retinal layers in surgically closed macular holes (MHs) after removal of the internal limiting membrane (ILM). PATIENTS AND METHODS: Medical records of 26 consecutive patients who underwent vitrectomy and removal of the ILM for idiopathic MH were retrospectively reviewed. En face optical coherence tomography images were exported at the level of the choroid, ellipsoid zone (EZ), and inner plexiform layer (IPL) at baseline and at ...

Purpose: This study investigated whether filtering blebs can be evaluated using optical coherence tomography angiography (OCT-A) and compared vascularity parameters with conventional bleb grading systems. Methods: A total of 92 patients with glaucoma, who underwent mitomycin C-augmented trabeculectomy, were enrolled in this study, and 92 eyes were assessed in total. The participants underwent OCT-A in external mode and anterior segment photography for bleb evaluation. For evaluation of bleb vasc...

To compare vascular displacement in the macula after surgical closure of idiopathic macular hole (MH) after single-layered inverted internal limiting membrane (ILM) flap technique and conventional ILM removal.This retrospective study included patients who underwent either vitrectomy and ILM removal only or vitrectomy with single-layered inverted ILM flap for idiopathic MH larger than 400 μm from 2012 to 2015. A customized program compared the positions of the retinal vessels in the macula betwee...
