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...

Visual acuity outcomes in Coat’s disease by classification stage

This is a retrospective study of 160 consecutive patients with Coat’s disease under the Shields classification, with Snellen visual acuity (VA) pre and post treatment. Affected eyes were categorised based on the Shields classification: Stage 1: retinal telangiectasia onlyStage 2a:...

The visual field of empathy: What ophthalmology taught me about seeing the patient

It was a busy shift on the ward. Amongst the chest pains and fevers was an older woman referred for confusion. She was quiet, polite, and compliant – the kind of patient who doesn’t raise alarms. As we spoke, I...

Visual fatigue associated with greater online digital use during the pandemic

The purpose of this study was to subjectively examine the degree of visual fatigue in children attending online classes during the pandemic and objectively evaluate accommodation and vergence of these children. The study was undertaken from July-August 2020 and recruited...

Is virtual reality perimetry as reliable as static perimetry in detecting neurological visual field loss?

This study compares agreement between virtual reality perimetry (VRP) and static automated perimetry (SAP) in a variety of neuro-ophthalmological conditions. For this work the Order of Magnitude (OM) VR-based visual field assessment system was used which has been developed by...

Hypothesis for poor visual outcomes in myeline oligodendrocyte glycoprotein-related optic neuritis after first attack

The authors present a retrospective case review with the aim of describing the group of patients with myelin-oligodendrocyte glycoprotein-associated optic neuritis (MOG-ON) who had poor visual outcomes following their first attack despite rapid treatment. The study was conducted at a...

How good does my vision have to be to drive this thing? Visual standards for various occupations

We can all picture that moment in clinic: you are about to tell someone that they’re no longer legally able to drive, ready to deploy our ‘breaking bad news’ techniques. For some patients this may have been expected, or they...

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...

Traumatic macular holes: reconstructive changes in foveal microstructures and visual predictor analysis, following surgical repair

The purpose of this paper was to investigate the reconstructive changes in foveal microstructures postoperatively and analyse the visual predictors in eyes with surgically closed traumatic macular holes (TMHs). This retrospective study analysed the data collected from 71 eyes of...

Using a driving simulator to explore the effect of visual field loss from optic disc drusen

The purpose of this study was to compare driving simulator performance of participants with visual field loss (VFL) from optic disc drusen (ODD) with a normally sighted control group and a group of individuals with glaucoma. Data on performance and...

Newer generation IOL platforms designed for high-quality visual performance after cataract surgery

Expanding intraocular lens (IOL) capabilities provide broadening options, ranging from next-generation monofocal IOLs for basic cataract surgery, to specialised premium IOLs for lens-based presbyopia correction and astigmatism correction at the time of cataract surgery. Rod McNeil considers several newer alternative...

Report on preoperative visual acuities of patients from two AMM surgical trips to Magdalena, Northern Bolivia

The Andean Medical Mission (AMM), founded in 2012, recently celebrated 12 years of dedicated service in the Bolivian Amazon, aiming to eliminate avoidable blindness. Over this period, AMM has successfully performed over 1700 surgeries, including for children with congenital or...
