Outcomes of corneal collagen crosslinking (CXL) in pseudophakic bullous keratopathy (PBK)

This was a retrospective non-comparative, interventional case series of 50 eyes in 50 patients with symptomatic PBK who underwent CXL (epithelium-off). Central corneal thickness (CCT), pain score, best corrected visual acuity (BCVA), and corneal transparency were recorded at baseline; at...

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...

Can closing the eyelid during riboflavin induction phase of crosslinking increase corneal thickness?

Corneal crosslinking (CXL) with riboflavin and UVA irradiation is the standard treatment for preventing progression of keratoconus. Thinning of the cornea during the riboflavin loading phase was reported in previous studies which used riboflavin with dextran. A minimum stromal thickness...

Characteristics of limbal lymphatic vasculature on confocal microscopy

This ex vivo study aims to describe the morphological characteristics of the human limbal lymphatic vasculature using confocal microscopy and immunofluorescence. Twelve corneal specimens are obtained from human donor eyes. These corneal buttons are not suitable for transplantation due to...

Does pregnancy cause progression of keratoconus in previously cross-linked corneas?

This is a prospective study involving 24 eyes of 19 patients with stabilised or regressed keratoconus after a successful accelerated cross linking (A-CXL) treatment. Patients were recruited at a routine follow-up visit in the first month of their pregnancy. The...

A comparison of light sources in retinal imaging

Before starting to talk about the light sources present in retinal imaging, it is necessary to start from the base: the light. Light is an electromagnetic wave whose smallest part is the photon (or quantum of light). A high frequency...

Surgical effect of limited membrane dissection

Strabismus surgery was performed with minimal dissection of Tenons sheath and minimal tissue manipulation compared to conventional methods for patients with pure horizontal strabismus – to evaluate the effect on surgical outcomes. The study included 54 patients; 52% female. Mean...

Static subjective visual vertical (SVV) in the normal visual system

Graviception is the perception of a persons’ orientation relative to gravitational force. This can be measured by means of subjective verticals, which can be divided into three tests: subjective visual vertical (SVV), subjective postural vertical (SPV) and subjective haptic vertical...

Amniotic membrane efficacy

This prospective randomised study evaluated the effect of amniotic membrane (AM) in reducing inflammation, fibrosis, adhesion formation and ocular movement restrictions following strabismus surgery. This study used 22 rabbits: all with superior rectus recession in both eyes with AM placed...

Brn3b neuroprotective effect in rat glaucoma model

An adeno-associated virus-directed overexpression of the Brn3b protein in hypothesised to confer neuroprotective effects in this paper. This is ultimately tested in a well-accepted rat glaucoma model (Morrison’s model: saline injection into episcleral veins of rat eyes with a force...

Abducens nerve palsy following surgical correction of craniosynostosis

The authors present two cases of unilateral abducens palsy secondary to a recent trans-sutural distraction osteogenesis (TSuDO) operation for craniosynostosis. The basic principle of the TSuDO procedure is described as dissection and distraction of the prematurely fused sutures. This complication...

Clinical predictors of proliferative sickle cell retinopathy

Sickle Cell Disease (SCD) is an inherited disorder resulting in production of Haemoglobin S (HbS), which aggregates in conditions of hypoxia, acidosis or hyperosmolarity. This leads to vascular stasis, thrombosis and ischaemia. The authors present a cross-sectional study (45 consecutive...
