Contrast sensitivity comparisons for Pelli Robson, Hiding Heidi and Double Happy tests
The authors aimed to compare contrast thresholds and measure agreement across current paediatric assessment of contrast sensitivity with Hiding Heidi and Double Happy contrast sensitivity tests vs. the gold-standard Pelli Robson chart. Reduced contrast levels were similar under different light...
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...
Cost-effectiveness framework discussion for vision screening
The authors present a discussion paper on hypothetical, but representative, examples of post-referral costs that may result from different screening options up to the point of discharge from specific services. Data was taken from a recent (2019) systematic review (with...
Providing well-developed education materials can improve follow-up attendance for retinopathy of prematurity screening
he authors present a repeated measures study with parents of children at risk of developing retinopathy of prematurity (ROP). Inclusion criteria for the study was parents with children born at <32 weeks or with a birth weight under 1.5kg. Participants...
New grading description for ROP retinal changes for those meeting termination of vision screening guidelines
This study reports and characterises residual retinal changes seen in eyes that meet criteria for termination of acute retinal screening exams. A novel grading system was used in which retinal exams were graded A to E. ‘A’ was defined as...
Increase in myopia during the Covid-19 lockdown periods
The aim of this study was to examine the effect of the Covid-19-related lockdown on myopia progression of school-aged children in Lebanon. The authors reviewed 443 records of myopic children aged 3–18 years (mean 11.81 ±3.67) presenting from January 2020...

EYE - Vitreo-Retinal
A classification system has been proposed for myopic maculopathy: grade 0 (no myopic retinal lesions), grade 1 (tessellated fundus), grade 2 (diffuse chorioretinal atrophy (CRA)), grade 3 (patchy CRA), and grade 4 (macular atrophy). Tessellated fundus is defined as the...

EYE - Glaucoma
This prospective observational study involved 47 patients diagnosed with primary open angle glaucoma (POAG) examined to investigate their postural blood pressure response and its potential correlation with the severity of glaucomatous optic neuropathy (GON). Participants underwent intraocular pressure and systemic...

EYE - Neuro-ophthalmology
Central retinal artery occlusion (CRAO) is a subtype of acute ischaemic stroke which results in severe visual loss. Acute CRAO is equivalent to a brain acute ischaemic stroke (AIS), as the obstruction of the central retinal artery (CRA) causes end-organ...

EYE - Neuro-ophthalmology
Idiopathic intracranial hypertension (IIH) is characterised by elevated intracranial pressure (ICP), which leads to optic nerve head swelling and a risk of visual loss. The impact of straining and exercise on ICP regulation is poorly understood yet clinically relevant to...
Review of efficacy and safety of tetracaine drops in strabismus surgery
Tetracaine is a topical anaesthetic drug used to anesthetise the eye and surrounding areas during strabismus surgery. It is generally safe and well tolerated but can cause mild adverse reactions at the site of use and, in rare cases, serious...
