Hess vs. Harms vs. PCT measurements

This study aimed to compare the results of the different tests in 36 strabismus patients and 18 healthy controls aged 6-81 years. Tests included alternate prism cover test, Hess screen and Harms screen. Because of glasses restrictions with the Harms...

Exotropic angle by PACT vs under translucent cover

The authors aimed to validate the photographic analysis with a translucent cover by comparing the results obtained from this analysis with the angle obtained by prism cover test (PACT) in patients with intermittent exotropia. This was a retrospective review of...

Test retest values for TNO, Frisby, Lang stereopad and Asteroid stereoacuity tests

This study aimed to determine test-retest variability of four different measurements of stereoacuity including TNO, Frisby, Lang stereopad and Asteroid, and compare stereoacuity values between tests in an adult population. Participants were >18 years of age (mean 38 years, SD...

Prism fusional vergence measures for Risley vs prism bar measurements

This study sought to investigate the agreement between the phoropter Risley and the prism bar prism fusional vergence amplitudes among a normal sample of Ghanaian children aged 8–17 years. This was a school-based study of 2300 children. Of 2300, 116...

Initiatives in macular service provision

A report from Monitor in October 2015 identifies good practices that will realise most of the potential productivity gain in elective care available to NHS hospitals. These include: stratifying patients by risk and creating low-complexity pathways for lower-risk patients (tailoring...

Long-term corneal crosslinking results in paediatric eyes

This prospective longitudinal study examined patients 18 years of age or less with progressive keratoconus, who underwent corneal crosslinking and completed 10 years of follow-up. Crosslinking protocol involved removal of epithelium, 10 minutes of riboflavin soaking, followed by 30 minutes...

The Eye Health Network – an ‘optometry-first’ approach to eye care

Historically, in NHS Grampian, ophthalmology and optometry worked separately, with even the process of optometry referral to hospital occurring only at the behest of the patient’s general practitioner (GP). Criteria for referral were not discussed and feedback after referral was...

Beyond ‘Shield and Ship’: a novel device (Eye-Aid) to provide temporary aqueous tamponade

The authors present a pilot efficacy study of the novel Eye-Aid device in a porcine model of full-thickness corneal wounds to mitigate anterior chamber collapse in the forward military environment. Currently, the ‘Shield and Ship’ paradigm taught to military healthcare...

Normative database of OCT measurements in children

This study aimed to establish a normative database of optical coherence tomography (OCT) (Cirrus SD-OCT) parameters and to investigate if gender, ethnicity and axial length affect these measures by evaluating the effects of age and spherical equivalent refraction (SER) in...

What’s next in retinal imaging? Faster, deeper and full-on

Fast-evolving technological leaps are opening the way toward clinically useful ocular coherence angiography, generating 3-dimensional microvasculature maps without intravenous dye injection, as well as whole-eye imaging, handheld patient-operated optical coherence tomography (OCT) devices and, for challenging vitreoretinal procedures, integrated intraoperative...

My Top Five: Key insights from recent research into uveitis in adults

Uveitis, characterised by inflammation of the uvea – the eye’s middle layer comprising the iris, ciliary body, and choroid – remains a leading cause of visual impairment worldwide [1]. It primarily affects adults aged 20–50 years. Untreated uveitis may cause...
