Surgical correction of lacrimal gland prolapse

This is a systematic review of published literature on the management of lacrimal gland prolapse or ptosis. The authors found 16 publications which contained a description of any surgical correction of a prolapsed lacrimal gland, comprising seven case reports, four...

Using OCT to screen and monitor Alzheimer’s disease

Alzheimer’s disease (AD) is a neurodegenerative illness characterised by progressive decline in cognitive function. AD is the main cause of dementia worldwide. Over recent years researchers have strived to find biomarkers to diagnose AD, particularly in the early stages of...

Muscle insertion measurement by ultrasound biomicroscopy

The aim of this study was to evaluate the accuracy of ultrasound biomicroscopy (UBM) preoperatively and postoperatively in patients having primary horizontal muscle surgery. Sixteen eyes of 15 patients with concomitant horizontal strabismus were evaluated; mean age 21.1 ±3.3 years,...

Normal videonystagmography data

The authors report on the smooth pursuit and saccadic eye movement waveforms elicited from normal patients while viewing standardised calibrated targets. Serial trials were performed on each patient to determine test / retest reliability: nine trials producing 117 results by...

Diagnosis and management of paediatric keratoconus

This article reviews the current literature on paediatric keratoconus diagnosis and management. Paediatric cases pose challenges as they may not vocalise unilateral changes, difficulty in obtaining reliable imaging, faster rates of progression, difficultly with contact lenses and presumed worse outcomes...

B-scan ultrasonography

B-scan ultrasonography is commonly employed for the diagnosis and follow-up of ocular trauma. This retrospective study looked at the accuracy and predictive ability of B-scan ultrasonography following open globe repair. Of the 965 patients identified with open globe injuries at...

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...

Reliability of Fluorescein Dye Disappearance Test (FDDT)

The authors look at the role of the FDDT in the evaluation of adults with primary acquired nasolacrimal duct obstruction (PANDO) and its correlation with the age and severity of epiphora. They report the results of a prospective cross-sectional comparative...

Retinoblastoma – the challenges of a rare cancer and the role of international partnerships

Introduction: the global challenge The global burden of retinoblastoma (Rb) is one in 15,000-18,000 live births, which equates to 8000 new cases worldwide each year. The global disparities in Rb outcome represent a paradigm of health inequality worldwide [1]. In...

Decontamination and sterilisation of surgical instruments and medical devices

Ann-Marie Ablett is a Theatre Nurse and Team Leader who volunteers with Orbis. This has allowed her to gain a wealth of experience on ophthalmic procedures, nursing in under-privileged parts of the world, leadership, management and use of scarce resources....

Using graphical illustration to predict giant cell arteritis

A nomogram is a chart or graph of scaled variables that facilitates the approximate computation of a mathematical function via intersecting lines. The objective of this study was to illustrate the use of a nomogram for the prediction of giant...

Viral uveitis

This review covers viral causes of anterior uveitis. A viral aetiology should be suspected when anterior uveitis is accompanied by ocular hypertension, diffuse stellate keratic precipitates or the presence of iris atrophy. Most common viruses associated are herpes simplex, varicella-zoster...
