SQUARE GRID DEFORMATION ANALYSIS OF THE MACULA AND POSTOPERATIVE METAMORPHOPSIA AFTER MACULAR HOLE SURGERY.

Purpose: To investigate the correlation between postoperative metamorphopsia and macular deformation after macular hole surgery.

Methods: This study included 28 eyes of 28 patients who underwent vitrectomy and internal limiting membrane removal for an idiopathic macular hole. The retinal vasculatures were compared between preoperative and postoperative photographs, and postoperative deformation of the macula was assessed as deformation of the square grid.

Displacement of the Foveal Retinal Layers After Macular Hole Surgery Assessed Using En Face Optical Coherence Tomography Images.

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 1, 3, and 6 months.

Comparison of conjunctival vascularity changes using optical coherence tomography angiography after trabeculectomy and phacotrabeculectomy.

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.

Methods: We retrospectively reviewed data for 72 eyes from 72 glaucoma patients who underwent MMC-augmented trabeculectomy with/without cataract surgery. Bleb area scans were obtained using OCT-A during the preoperative period; 1, 2, 4, and 6 weeks postoperatively; and 2, 4, and 6 months postoperatively.

Evaluation of Functional Filtering Bleb Using Optical Coherence Tomography Angiography.

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.

Comparison between refractive outcomes between macula-on and macula-off retinal detachments after phaco-vitrectomy.

Purpose: To evaluate axial length (AL) measurements and refractive outcomes in vitrectomy combined with cataract operation for rhegmatogenous retinal detachment (RRD) with wholly detached macula.

Study Design: Retrospective, consecutive, comparative, clinical study.

Methods: We reviewed the data of patients treated by vitrectomy combined with cataract operation for RRD.

Bruch's membrane opening-minimum rim width and visual field loss in glaucoma: a broken stick analysis.

Aim: To determine the Bruch's membrane opening-minimum rim width (BMO-MRW) tipping point where corresponding visual field (VF) damages become detectable.

Methods: A total of 85 normal subjects and 83 glaucoma patients (one eye per participant) were recruited for the study. All of the patients had VF examinations and spectral-domain optical coherence tomography to measure the BMO-MRW.

Vascular Displacement in Idiopathic Macular Hole after Single-layered Inverted Internal Limiting Membrane Flap Surgery.

Purpose: 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.

Methods: 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 between preoperative and postoperative photographs.

Functional end-arterial circulation of the choroid assessed by using fat embolism and electric circuit simulation.

The discrepancy in the choroidal circulation between anatomy and function has remained unsolved for several decades. Postmortem cast studies revealed extensive anastomotic channels, but angiographic studies indicated end-arterial circulation. We carried out experimental fat embolism in cats and electric circuit simulation.

TOPOGRAPHIC CHANGES OF THE MACULA AFTER CLOSURE OF IDIOPATHIC MACULAR HOLE.

Purpose: To investigate retinal displacement in the macula after surgical closure of idiopathic macular hole and to identify factors correlated with displacement.

Methods: This retrospective multicenter study included 73 eyes of 73 patients having idiopathic macular hole. A custom program was developed to compare the position of the retinal vessels in the macula between preoperative and postoperative photographs.
