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...

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...

Moorfields DALK wet lab

Deep Anterior Lamellar Keratoplasty (DALK) is the most challenging technique of corneal transplantation. Moorfields Eye Hospital performs a high volume of DALK surgeries and is currently the leading centre in corneal transplantation in Europe. The Moorfields DALK wet lab, delivered...

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...

The results of the last survey Dec22

I am regularly faced with litigation whereby the claimant’s cornea has decompensated after cataract surgery. The procedure may have been complicated but sometimes it is not. The eye may have been high risk, for example, a shallow anterior chamber with...

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,...

Laser corneal refractive procedures – a review

Evolution of refractive surgery stays true to the quote of Theodore Roosevelt: “The more you know about the past, the better prepared you are for the future.” Refractive surgery is an evolving field, which thanks modern technologies for refining ideas...

In conversation with Andrena McElvanney (President, MCLOSA)

We spoke to Andrena about MCLOSA's annual meeting this November, key developments in cornea and external eye disease, and plans for the association’s 30th anniversary. Andrena McElvanney (top, second from right) and the OSI council members. The Medical Contact Lens...

Scheimpflug vs. OCT in measuring corneal thickness

The authors report on the reproducibility and repeatability of corneal thickness measurements using three different Scheimpflug imaging cameras (Pentacam, Sirius and Galilei) and one Fourier-domain optical coherence tomography (OCT) system (RTvue-100). The rationale for this study is that corneal thickness...

Effect of trabeculectomy on corneal endothelial cell loss

This is a prospective study of 117 eyes for two years after trabeculectomy, to investigate the corneal endothelial cell density (CECD) by specular microscopy prior to and after surgery on a six monthly basis. At six, 12, 18 and 24...
