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...
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...The results of the last survey Dec22

EYE - General
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,...
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...In conversation with Andrena McElvanney (President, MCLOSA)

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...

EYE - Glaucoma
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...
Are corneal guttata an additional risk factor in complicated cataract surgery needing a future corneal transplant?
This registry-based cohort study from Sweden utilised data from the Swedish National Cataract Registry and the Swedish Cornea Transplant Registry. Patients who underwent phacoemulsification with a posterior intraocular lens between 2010 and 2012 numbered 192,476. Of these cases, 288 underwent...Crystalline keratopathy in monoclonal gammopathy of undetermined significance

EYE - Cornea
Monoclonal gammopathies encompass a group of plasma cell disorders characterised by the excessive production of abnormal monoclonal immunoglobulins in the bloodstream [1]. This category includes multiple myeloma, monoclonal gammopathy of undetermined significance (MGUS), amyloidosis and other lymphoproliferative disorders. Monoclonal gammopathy...
Silent keratitis in failed graft
This study examined rates of asymptomatic keratitis in failed full thickness corneal grafts, which were not picked up clinically preoperatively. During a five year period 53 penetrating keratoplasties (PK) were performed for long-standing graft decompensation with stromal opacity and /...

EYE - Oculoplastic
This is the first reported use of an acellular nerve allograft for corneal neurotisation. Seven patients received a 7cm long commercially prepared acellular nerve allograft. This was coapted to a functioning supratrochlear, supraorbital or infraorbital nerve and then tunnelled to...
