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...

Autophagy in lens mitochondria loss

The lens consists of a monolayer of epithelial cells that overlies fibre cells that differentiate from epithelial cells at the equator. While developing, fibre cells need mitochondria to provide energy, as they mature they lose these and other organelles to...

Long-term improvement of stereopsis in intermittent refractive esotropia

This was a retrospective study to review the records of patients with refractive accommodative esotropia (RAET) to determine long-term stereoacuity (SA) improvement in those that showed initial poor or no stereopsis. The study included 79 patients; 54% male and mean...

Preterm birth and refractive error in an Indian infant population

This study was undertaken to identify and compare the changes in refractive outcome in infants with and without retinopathy of prematurity (ROP), to inform incidence of refractive error. This was a prospective study of 300 consecutive premature infants with birth...

‘At risk’ corneas are more easily identified with SCORE

Risk assessment of post-LASIK corneal ectasia in refractive surgery patients is now a more exact, objective, evaluation thanks to the work of Heidelberg Engineering and a leading research partner in Paris.

Optical quality difference between monofocal and multifocal intraocular lenses

It is well known that multifocal intraocular lenses (IOLs) can generate more than one focus to restore distance and near vision, but patients may experience adverse optical phenomena such as decreased contrast sensitivity and induced glare or halos. The authors...

Surgical technique for small-angle hypertropia

In order to treat small-angle hypertropia of <5PF associated with mild / moderate upshoot in adduction, an option is to suture the inferior oblique (IO) belly to the sclera following its natural muscle direction or with anterior transposition. This study...

Results of STENTube for lacrimal intubation

The STENTube is designed with a varied diameter – a thin central segment with a diameter of 0.86mm and distal tube segments with larger 1.3mm diameter. The thin central segment is exposed at the medial canthus. The distal tubes tamponade...

Patient safety – is this achieved in optometry with CET?

Collecting points and ticking boxes – as we come to the end of another three year cycle of continuing education and training (CET), the rush to ensure that everything has been completed on the myGOC (General Optical Council) dashboard feels...

The Ophthalmic Study Guide for Nurses and Health Professionals (2nd edition)

In the last decade, care provision in ophthalmology has changed dramatically. Due to increasing demands on the service, the roles of nurses and other healthcare professionals have expanded to encompass work that was traditionally carried out by doctors. This model...
