PURPOSE Little is known about the behavior of the endothelial cell (EC) layer following keratoplasty. In vitro experiments suggested that the peripheral endothelium might have a higher regenerative capacity than the central endothelium, and some authors hypothesized that endothelial progenitor cells are present in the limbal area. Thus, we analyzed the corneal endothelial regenerative capacity ...

Corneal and plasma lipids were studied in a rabbit model to gain insight into the pathogenesis of secondary lipid keratopathy. Rabbits were divided into four groups in which a high cholesterol diet and corneal suture placement were varied to produce lipid keratopathy. In rabbits with lipid keratopathy, quantitative thin layer chromatography revealed that cholesterol esters comprised most of the...

OBJECTIVE To determine the intraoperative and early postoperative complications of manual sutureless cataract extraction. STUDY DESIGN Case series. PLACE AND DURATION OF STUDY Redo Eye Hospital, Rawalpindi, Pakistan, from January 2009 to December 2010. METHODOLOGY Three hundred patients of cataract through purposive non-probability sampling were selected. The patients underwent manual sut...

PURPOSE To introduce autologous tragal perichondrium transplantation as a novel surgical modality for the management of intractable symptomatic bullous keratopathy. METHODS In three eyes of three patients with painful bullous keratopathy, autologous tragal perichondria were transplanted on the corneal surface with the human amniotic membrane transplanted above. We included an additional three...

PURPOSE To describe in vivo confocal microscopy findings in patients with different stages of amiodarone-induced keratopathy, and correlate biomicroscopy stages with confocal stages. METHODS Twenty eyes of 10 patients (6 men and 4 women), who receive treatment with amiodarone were selected for the study with confocal microscopy (MC). RESULTS The average age was 58 +/- 6.2 years (50-66 years...

Seven cases with posterior polymorphous changes of the cornea are reported. After clinical and pathological examination of the above cases, as well as a short review of the literature, the following points are made: (1) Some cases are congenital, being either familial or sporadic, but others are acquired. (2) The term "posterior polymorphous keratopathy" covers all the variants of the condition...

ber, similar to fungi. Recently, microsporidia have been phylogenetically shown to be fungi, and their tissue behavior akin to that of fungi would be expected. Our patient had clinical features of herpetic viral endotheliitis at the initial visit, which improved initially with antiviral treatment. There is a possibility that the patient may have had viral keratitis initially and then became sec...
