Transcriptomic analysis of ocular tissues

Transcriptomics is defined as the analysis of the complete set of RNA transcripts present in a cell under different circumstances, quiescent versus challenge, by microarray analysis. Comparison of transcriptomes identifies genes that are differentially expressed in different cell populations under...

Inhibiting high-risk corneal allografts

The cornea is an immune privileged site and as such corneal transplants are very successful. However, in situations where this privilege is lost the failure rises substantially. To combat rejection inhibition of the immune responses depends on steroids and other...

Descemetorhexis without endothelial keratoplasty

This retrospective study examined outcomes of the largest reported series of eyes, which underwent Descemetorhexis without endothelial keratoplasty (DWEK) for Fuch’s endothelial dystrophy with mean 10 months of follow-up. Seventeen eyes were included in analysis; with 82.4% achieving corneal clearance...

BESTi: a new index to detect subclinical keratoconus

In this multicentre, case-control study, the authors develop a new index, named Boosted Ectasia Susceptibility Tomography Index (BESTi), to detect early cases of keratoconus. This index was derived from multiple logistic regression analysis of 22 variables of tomography scans. The...

Corneal suture sample evaluation

This is a prospective study of 35 patients’ suture samples taken from a tertiary cornea clinic, Miami, Florida, with a history of penetrating keratoplasty. The aim is to study the relationship between corneal suture bacteriology, biofilm and the clinical setting,...

MicroRNA inhibits corneal neovascularisation

MicroRNAs (miR) are small non-coding RNA that target mRNA for destruction. MiR target about 30% of the protein coding genes and fine tune their expression. MiR have been shown to be involved in several cellular processes including cell cycle, tissue...

Platelet rich fibrin membrane for descemetocele

This case series described the use of a novel technique in the treatment of descemetocele. Three patients developed descemetoceles following infective keratitis with impending risk of corneal perforation. Platelet rich fibrin (PRF) membrane was prepared using 8ml of fresh venous...

Central corneal and epithelial thickness measured by Fourier domain OCT

This study examined intraobserver and interobserver reproducibility of corneal thickness (CT) and epithelial thickness (ET) measurement of Fourier domain OCT (RTVue) in 23 healthy volunteers. RTVue is capable of producing 26,000 A scans per second with depth resolution of 5µm....

Differences of the anterior segment parameters in children with Down syndrome

This cross-sectional study was designed in order to demonstrate the differences in anterior segment parameters in children with trisomy 21. This is important as it may impact on surgical planning when undertaking procedures in the anterior segment such as corneal...

Evaluation of keratometry with a novel colour LED corneal topographer

The Cassini topographer (i-Optics), which analyses corneal shape based on the reconstruction of specular reflections on 679 coloured LEDs, generates keratometry and is the new machine being compared in this study with other keratometry devices. The prospective comparative study included...

Corneal thickness in patients with diabetic peripheral neuropathy

This cross-sectional study assessed corneal thickness in association with diabetic peripheral neuropathy (DPN) severity. The study also tried to identify the layer of the cornea most affected by DPN status. Performed at the University of Michigan the study included three...

Depth and width of corneal wounds post corneal foreign body removal

This was a prospective study of 63 eyes of 63 patients undergoing corneal foreign body (FB) removal with a 27G needle at the slit-lamp; 96.8% of the patients were men with mean age 35.8 ±11.0 years. Regarding location of FBs,...
