Automated Bruckner device accuracy

The authors developed a Bruckner device, examined volunteers and determined the relation between the luminance of the red fundus reflex and eye rotation. Eye rotation was varied continuously both horizontally (-7 to 8 degrees) and vertically (five degree total range)...

Central corneal and epithelial thickness measured by Fourier domain OCT

This study examined intraobserver and interobserver reproducibility of corneal thickness (CT) and epithelial thickness (ET) measurement of Fourier domain OCT (RTVue) in 23 healthy volunteers. RTVue is capable of producing 26,000 A scans per second with depth resolution of 5µm....

Trochleitis features

The authors evaluate the epidemiology, clinical signs, treatment and outcomes of trochleitis in a retrospective review of 59 cases. Estimated prevalence was 12 per 100,000. Eighty-six percent were female and mean age was 43±18 years. All but one case was...

Conversion factors for fovea on / off detachments

This is a retrospective study of medical records in a single unit over a 14 year period from January 2001 – December 2014, of patients who converted from fovea-on to fovea-off rhegmatogenous retinal detachment (RRD). Ten cases were identified while...

Effect of single intravitreal injection of bevacizumab on contrast sensitivity in patients with central retinal vein occlusion

Central retinal vein occlusion is the second most common retinal vascular disorder after diabetic retinopathy. There are many studies reporting the efficacy of intravitreal anti-VEGF injections for macular oedema secondary to retinal vein occlusions. This paper looks at the contrast...

Effects of topical anaesthetic on intraocular pressure

This prospective interventional study assessed the effects of repeated intraocular pressure (IOP) using Goldmann applanation tonometry and applanation resonance tonometry in six volunteers. Previous literature supports IOP reduction using repeated applanation tonometry. Repeated IOP measures were taken alternately on 12...

Visual outcomes, visual fields and optical coherence tomography in paediatric craniopharyngioma

This study reviews the visual outcomes of ten patients under the age of 18 years with craniopharyngioma. The paper also reviews the correlation between visual field (VF) testing and optical coherence tomography (OCT) examination and evaluates the role of OCT...
