PURPOSE To describe the differences of corneal endothelial cell densities, cell size variability and cell hexagonality in cataract populations of south Asia between sexes and ethnic groups. METHODS 1,235 eyes of 1,235 male and female patients 40-75 years of age with senile cataract were examined with non contact specular microscopy with semi-automated analysis technique. The cell data of the ...

Endothelial cell loss following penetrating keratoplasty is progressive, with greater loss in the perioperative time period. However, we do not know why, for example, a density of 500 cells/mm stabilizes in some eyes maintaining corneal clarity, whereas a similar density in other eyes leads to late onset graft failure. Can one predict the decay of cells to explain this example? Why do we have g...

PURPOSE To study the effect of torsional phacoemulsification energy on corneal endothelium evaluating the relationship between changes of endothelial cells and postoperative visual acuity. METHODS This prospective clinical observational cohort study included 50 patients with cataract who underwent torsional phacoemulsification. Sequential quantitative and qualitative morphometric endothelial ...

AIM Different trephination methods may lead to differences in degree of tissue damage and endothelial cell loss, which both influence the outcome of penetrating keratoplasty. Light, transmission, and scanning electron microscopy were used to compare the ultrastructural appearance of the cut edges and the endothelial cell loss in 26 human corneal donor buttons obtained by trephination with the s...

A patient with Fuch's corneal dystrophy, sensorineural hearing loss, diabetes, cardiac conduction defects, ataxia, and hyperreflexia is described. Analysis of lymphocyte mitochondrial DNA showed missense mutations usually associated with Leber's hereditary optic neuropathy. The occurrence of Fuch's dystrophy in this patient and the biology of corneal endothelial cells suggest that mitochondrial...

High endothelial cell density (ECD) is essential for the corneal graft clarity. We evaluated ECD loss in 120 eyes that underwent penetrating keratoplasty (PK) in Eye Clinic Svjetlost in a one year follow up period. Patients were divided into 3 groups of high (N = 35), intermediate (N = 31) and low risk (N = 54) for graft failure. Postoperative central endothelial density, coefficient of variati...

PURPOSE Fuchs endothelial corneal dystrophy (FECD) results in loss of vision associated with progressive corneal edema and loss of corneal transparency. The aim of the study was to evaluate changes in ZEB1, COL8A2, SLC4A11, and TCF4 rs613872 and correlate them with clinical findings. METHODS Eighty-two patients with clinically diagnosed FECD and 143 controls were recruited during the period 2...

PURPOSE Corneal edema is a significant component of the various forms of herpes simplex virus type 1 (HSV-1)-induced stromal disease. Maintenance of corneal thickness, a reflection of corneal hydration, depends on a physical barrier formed by endothelial cell-cell junctions and by the activity of Na+/K(+)-ATPase pumps that regulate ion flux and thus influence water movement through this cell la...

Diabetic keratopathy is an ocular complication that occurs with diabetes. In the present study, the effect of diabetic keratopathy on corneal optical density, central corneal thickness, and corneal endothelial cell count was investigated. One hundred and eighty diabetic patients (360 eyes) were enrolled in the study during the period from March, 2012 to March, 2013. The patients were divided in...

Corneal endothelial dysfunctions occurring in patients with Fuchs' endothelial corneal dystrophy, pseudoexfoliation syndrome, corneal endotheliitis, and surgically induced corneal endothelial damage cause blindness due to the loss of endothelial function that maintains corneal transparency. Transplantation of cultivated corneal endothelial cells (CECs) has been researched to repair endothelial ...
