background: correlations between bone marrow, heart, kidney, liver, skin and lung transplant rejection or survival with human cytokine gene polymorphisms have been described. there are also reports about the role of cytokines and tumor necrosis factors-alpha (tnf-α) on corneal transplant in animal models. further studies are needed to clarify the role of cytokines in corneal allograft rejection...

Dasa-NLC could significantly inhibit the corneal neovascularization.

Aims: Selective laser trabeculoplasty (SLT) (Lumenis, Santa Clara, CA) was developed in 1999 as a means to lower IOP in patients with glaucoma. It is a relatively safe procedure. We report a rare side effect of corneal opacity and stromal haze with corneal thinning and hyperopic shift following SLT. Presentation of Case: Case report. Results: A 50 year-old Asian male who underwent SLT OD develo...

Introduction To evaluate the expression patterns of cytokeratin (K) 12, 13, and 19 in normal epithelium of the human ocular surface to determine whether K13 could be used as a marker for conjunctival epithelium. Methods: Total RNA was isolated from the human conjunctiva and central cornea. Those transcripts that had threefolds or higher expression levels in the conjunctiva than the cornea wer...

AIMS To investigate the frequency of corneal guttata in patients with a corneal dystrophy resulting from an Arg124His (R124H) mutation of betaig-h3 gene. METHODS Slit lamp examination was performed on 30 eyes with corneal dystrophy from a genetically confirmed betaig-h3 R124H mutation and on 50 age matched control eyes. The stage of the corneal dystrophy was classified as stage 0, I, or II an...

Accumulating evidence supports the dogma that the corneal epithelium is regenerated by stem cells located exclusively in the limbal niche, at the corneal periphery. Accordingly, limbal stem cells (LSCs) give rise to progenitors that proliferate and migrate centripetally to repopulate the corneal epithelium, which has a short turnover. Moreover, LSC loss leads to corneal opacity and blindness, w...

PURPOSE To evaluate the changes in corneal transparency and thickness measured objectively using Pentacam Scheimpflug (Oculus Optikgeräte GmbH) corneal tomography (densitometry) after corneal cross-linking (CXL). METHODS Twenty-two eyes from 15 patients with keratoconus underwent CXL. Corneal thickness and curvature as well as lens and corneal densitometry were measured at baseline and 1, 3, ...

AIMS To determine optimal conditions for enhancing corneal allograft survival through oral administration of donor specific corneal cells. METHODS A mouse model of penetrating keratoplasty was used to evaluate the efficacy and optimal conditions for preventing immunological rejection of corneal allografts. C3H corneal grafts were transplanted orthotopically to CB6F1 recipients and represented...
