Comparison of two visual acuity test versions for different distances in a paediatric population
The authors present the findings of a study which aimed to determine whether using 2 metre and 4 metre retro-illuminated ETDRS charts are comparable in children. Order of testing was standardised (right eye, left eye, binocular), however different charts were...
Home testing versus in-person visual acuity test results
This retrospective review compared visual acuity findings by parents / carers during telehealth consultations compared with their subsequent in-person tests. Parents were given an information pack with testing instructions for home tests. The study included 43 patients (86 eyes) with...
Children’s visual acuity test without professional supervision
With increasing outpatient demand there has been an innovative shift to involve patients managing their own condition. This article compares visual testing carried out by an orthoptist with usual clinical methods, an orthoptist using the iSIGHT Test Pro and a...
Testing near or distance visual acuity for change during amblyopia therapy
In this study, the authors aimed to determine if any differences occurred between near and distance visual acuity (VA) in a cohort of childhood untreated amblyopia. They recruited 54 patients with mean age 4.9 years, SD 0.44. Mean VA in...
Predicting outcome for visual acuity in optic neuritis associated with multiple sclerosis
The authors present a retrospective cohort study to evaluate key predictors of long-term high-contrast visual acuity following optic neuritis associated with multiple sclerosis. All patients coded as optic neuropathy and assessed by a neuro-ophthalmologist over a 10-year period were screened...
Retinal thickness and visual acuity change correlations after amblyopia occlusion therapy
This prospective study aimed to assess change in retinal nerve fibre layer (RNFL) and macular thickness, and clinical correlations with visual outcomes, after amblyopia treatment in 30 children with moderate to severe amblyopia. Mean age of children was 5.26 ±1.65...
Visual acuity improvement in amblyopic eyes following fellow eye vision loss
The authors present a systematic review with the aim of reporting how frequently and to what extent amblyopia recovers following the loss of vision in the fellow eye and identify any potential clinical predictors. Studies including adults with amblyopia and...How to examine the visual system Part 1: visual acuity, visual fields and eye movements
Asking candidates to perform an examination of the visual system, either as part of a full cranial nerve exam or as an individual entity, is a common station in practical examinations during medical school. It is important to practise for...
How does a tablet based stereoacuity test perform in children with normal and abnormal visual acuity?
The authors present a prospective cross-sectional comparison study at a single centre. Paediatric patients attending an ophthalmology outpatient clinic and likely to be cooperative were approached to participate. Participants underwent stereoacuity assessment using the ASTEROID and Titmus tests, usually in...
