Comparison of corneal deformation parameters in keratoconic and normal eyes

This study set out to compare biomechanical properties between normal and keratoconic eyes. It was a retrospective study evaluating 89 eyes (47 normal, 42 keratoconic) and a validation arm of 72 eyes (33 normal, 39 keratoconic) using a high speed...

Beware the disc in myopic patients

Glaucoma is a chronic and progressive optic neuropathy characterised by damage of retinal ganglion cells. Evaluation of structural damage of the optic nerve is important in glaucoma diagnosis. The ISNT rule states that the neuroretinal rim width is generally widest...

Fellow eye comparison of DMEK and PKP

This retrospective analysis of 11 patients who underwent penetrating keratoplasty (PKP) in their first eye followed by descemet membrane endothelial keratoplasty (DMEK) in their second eye studied visual and refractive outcomes. Intra and postoperative complications were compared and a subjective...

Contrast sensitivity after laser corneal surgery

This study group compared contrast sensitivity among participants undergoing wavefront-guided or wavefront-optimised photorefractive keratectomy (PRK) or laser-assisted in situ keratomileusis (LASIK) for the treatment of myopia or myopic astigmatism 12 months after surgery. This was a prospective, randomised clinical trial,...

Does the length of the school day have a role in age of myopia onset?

The authors prospectively collected the refractive data of myopic adults attending recruiting dispensing optician or ophthalmologist sites. Participants were recruited consecutively, giving verbal informed consent. Sites included a mix of urban and rural areas across eight sites. The following data...

Comparison of visual field indices between normal adults and children

The authors present a prospective observational study which aimed to compare visual field indices with retinal nerve fibre layer (RNFL) thickness using optical coherence tomography (OCT) in normal adults and children. Children aged 6–18 years were recruited from a single...

Changes in ocular biomarkers in Vogt-Koyanagi-Harada disease after pulse steroid therapy

This retrospective study aimed to evaluate the early and chronological changes in ocular biomarkers in patients of Vogt Koyanagi Harada (VKH) disease who received pulse steroid therapy. It further aimed to identify which biomarkers correlated with the best corrected visual...

Minimally Invasive Glaucoma Surgery: What options are there and when might they be considered?

In recent years there has been a rapid expansion in a group of operations termed ‘minimally invasive’ or ‘micro invasive’ glaucoma surgery (MIGS). These options generally offer less significant IOP reduction, but with a more favourable safety profile when compared...

Essentials of OCT in Ocular Disease

Sir Isaac Newton was the first to establish the technique of low coherence white light interferometry. Following on from this, the principle of laser interferometry as an imaging modality for retina was applied by David Huang and his associates in...
