A systematic literature review was performed evaluating articles examining the effects of pseudoexfoliation syndrome (PEX) and glaucoma (PEXG) on the cornea with a focus on the corneal endothelium. We searched for articles relevant to pseudoexfoliation syndrome, pseudoexfoliation glaucoma and corneal endothelial cell counts using Pubmed, Google Scholar Database, Web of Science and Cochrane Libr...
PURPOSE The aim of this study was to describe the aims, methods, donor and recipient cohort characteristics, and potential impact of the Cornea Preservation Time Study (CPTS). METHODS The CPTS is a randomized clinical trial conducted at 40 clinical sites (70 surgeons) designed to assess the effect of donor cornea preservation time (PT) on graft survival 3 years after Descemet stripping automa...
PURPOSE To report in vivo confocal microscopic (IVCM) features in corneal edema supported by histopathologic correlation. METHODS This was an observational study with evaluation of diagnostic technology. Twenty patients with clinically diagnosed corneal edema were involved, including 11 with Fuchs' endothelial dystrophy (FED). All cases, in addition to a control group of six normal eyes, were...
Confluent, cultured, rabbit corneal endothelial cells maintain a polygonal shape which is characteristic of these cells in vivo. When cultured in the presence of EGF (10 ng/ml) and/or indomethacin (1.0 microM), the endothelial cells have markedly different shapes at confluency. By morphometry, untreated cells are polygonal and have a maximum axis of 33 mu; EGF treatment causes a spindle-shaped ...
Purpose Descemet's membrane endothelial keratoplasty (DMEK) is a minimally invasive partial corneal transplant procedure used in patients with failing endothelial membranes. This study aims to identify those factors which influence the need for a rebubble of the corneal graft. Methods A total of 94 eyes that received DMEK between March 2014 and January 2016 at Vance Thompson Vision were used ...
Objective To compare corneal morphological parameters between diabetics and age matched non-diabetic control subjects and to evaluate the correlation of these parameters in relation to duration of diabetes mellitus (DM), glycemic status and severity of diabetic retinopathy.(DR). Methods This cross sectional comparative study was conducted at the Department of Ophthalmology, PNS Shifa Karachi ...
Purpose: To investigate the effect of smoking on corneal parameters, including Endothelial Cell Density, Central Corneal Thickness, Percent of Hexogonality, and Coefficient of Variation. Methods: This study was a systematic review and meta-analysis of published articles until the end of February 2019. To do this, the first search was done for creditable medical databases such as PubMed, and ISI...
OBJECTIVE To determine whether endothelial cell loss 5 years after successful corneal transplantation is related to the age of the donor. DESIGN Multicenter, prospective, double-masked clinical trial. PARTICIPANTS Three hundred forty-seven subjects participating in the Cornea Donor Study who had not experienced graft failure 5 years after corneal transplantation for a moderate-risk conditio...
The barrier and pump functions of the corneal endothelium are essential for the maintenance of corneal transparency. Although corneal transplantation is the only current therapy for treating corneal endothelial dysfunction, the potential of tissue-engineering techniques to provide highly efficient and less invasive therapy in comparison to corneal transplantation has been highly anticipated. Ho...
