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...

Management of traumatic corneal perforations with anterior lamellar techniques: The mini-DSAEK

The authors present the first case report in which a mini (reduced diameter) Descemet’s stripping automated endothelial keratoplasty (mini-DSAEK) has been used to manage a traumatic corneal perforation. A 69-year-old male presented with 6/36 best spectacle-corrected visual acuity (BSCVA) and...

Propranolol treatment of infantile haemangioma

This is a retrospective review of 104 patients treated for infantile haemangioma between January 2009 and July 2012. All patients underwent pretesting either with protocol A (administration of test dose with routine observations) or protocol B (cardiology clinic assessment, including...

Effects of phacoemulsification on IOP and drug use in glaucoma

For patients with comorbid cataract and primary open-angle glaucoma (POAG), guidance is lacking as to whether cataract extraction and traditional filtering surgery should be performed as a staged or combined procedure. Achieving this guidance requires an evidence-based understanding of the...

Amblyopia treatment review

This review paper summarises the main causes and neural mechanisms that characterise amblyopia. The authors analysed neuroanatomical, neurophysiological and electrophysiological studies in the literature to better understand actual treatment regimens and evaluate new therapeutic possibilities. They considered causes of strabismus,...

Which cover test method is the best starting point for prescribing temporary prisms?

A retrospective review of medical records was completed, identifying consecutive patients prescribed Fresnel prisms for diplopia, assessed using both simultaneous prism and cover test (SPCT) and prism and alternate cover test (PACT) by a single orthoptist over a 36-month period....

Cataract extraction and microperimetry

In this study, the authors assessed retinal sensitivity before and after cataract extraction, in an effort to understand how lens opacities may affect microperimetry results in glaucoma and macular diseases. Thirty patients awaiting cataract extraction were examined and their lens...

Iran prevalence of amblyopia

The authors aimed to determine the prevalence of amblyopia, its relation with refractive errors and its determinants. The target population was all children aged seven years in Iran. There were 3675 of 4157 children who participated (88.4%) with final analysis...

Comparison of SIA from femtosecond laser and manual CCIs for cataract surgery

This study group compared the differences in surgically induced astigmatism (SIA) vector, flattening effect, torque and wound architecture following both femtosecond laser and manual clear corneal incisions (CCIs). A double-armed, randomised, prospective case series was conducted. Cataract surgery was performed...

Comparing bimedial rectus recession and botulinum toxin for partially accommodative esotropia

The authors present a retrospective case review to compare bimedial rectus recession and botulinum toxin injection to the medial recti. This study was possible due to the different first-line preferences of the individual surgeons within the team. Inclusion criteria were...

Clinical Observation Days Pave Way for Next Generation of Optometrists

Optometry students at Glasgow Caledonian University have taken part in a series of clinical observation days at one of the UK’s leading eye surgery clinics, as part of a new programme giving student optometrists experience of modern day surgical practice.

Intermittent exotropia with a positive Bielchowsky head-tilt test

This is a retrospective study from Korea, of 118 patients’ charts with intermittent exotropia (IXT) and divided into two groups; 50 patients showed positive Bielchowsky head tilt test (BHTT) and 68 with negative BHTT. Significant differences (p<0.05) in the parameters...
