Forward-tilt technique for intraocular pressure measurement in upgaze

The authors suggest a technique to improve the accuracy of measuring IOP in upgaze using Goldmann applanation tonometry. Graves’ ophthalmopathy, also known as thyroid eye disease, is an autoimmune inflammatory condition affecting the orbit and periorbital tissues [1]. It was...

Blame the lens – not its position – in refractive surprise

Aetiology of postoperative refractive surprise Weber coined the term “wrong eye, wrong intraocular lens, wrong patient” in 2008 as an aide memoir of major factors believed to underlie refractive surprise – defined as a significant unintended difference between dioptric refraction...

Vitamin D and thyroid eye disease

This is a retrospective review of vitamin D levels in patients with thyroid eye disease (TED). Vitamin D levels in 89 patients with Grave’s disease and TED were compared against 89 patients with Grave’s disease and no TED. They also...

Use of Bagolini filter bars

The authors measured the percentage light transmission of filters on different Bagolini filter bars to evaluate whether a difference exists in density of suppression or strength of abnormal binocular single vision (BSV). A Sekonic dual spot photometer was used to...

Practical application of cataract risk stratification

This study assessed the practicability of a risk stratification system, the New Zealand Cataract Risk Stratification (NZCRS) in a major teaching hospital. The scoring system was as follows: three points for Dense cataract, pseudoexfoliation (PXF), phacodonesis, previous vitrectomy and only...

Effect of caffeine and low intensity endurance exercise on intraocular pressure

This placebo controlled, double blind, balanced crossover study reports in healthy individuals that 30 minutes of cycling caused a maximum of 2.7mmHg lowering of IOP. A caffeine dose of 4mg/kg 30 minutes prior to cycling negated this effect. The conclusion...

Eye movements in children with strabismus +/- amblyopia

The aim of this study was to detect eye movement recording abnormalities using different paradigms in children with strabismus in the absence or presence of amblyopia and compare these findings with age-matched children without strabismus. One hundred children were recruited...

Using contrast acuity and rapid number naming in Huntington’s disease

This study aimed to evaluate afferent and efferent visual function in Huntington’s disease (HD). HD is often portrayed by abnormal saccadic eye movements and afferent visual pathway involvement however these are poorly characterised and difficult to quantify at the bedside....

Impact of amblyopia on adult planning and problem solving

This study sought to evaluate whether monocular amblyopia has an impact on planning and problem solving in the adult population. The authors used the Tower of London (TOL) test to address this question. The TOL test was developed to assess...

A robotic armrest for ophthalmic surgery

Robot-assisted ophthalmic surgery has been the focus of intense interest in recent years. In this study, the authors tested the potential utility of a robotic armrest in ophthalmic surgery. The iArmS device consists of a forearm rest attached to a...

The effect of caffeine on pupil size and accommodation

Twenty-two young and healthy participants were recruited in this study. The authors showed that pupil size increased as a result of caffeine consumption. A more stable (lower variability of accommodation) accommodative response (AR) was induced by caffeine intake, whereas the...

Topical steroids and ptosis surgery

This is a retrospective review examining the effect of prior topical steroid use on patients undergoing ptosis surgery. Out of a total of 406 eyelids undergoing ptosis repairs, 44 had received topical steroids for an average of 3.7 years prior...
