GP contact lenses in nystagmus

The purpose of this study was to quantify and evaluate the effect of rigid gas permeable contact lenses (CLs) on visual acuity, contrast sensitivity and motor parameters of involuntary eye movements in hyperopic patients with infantile nystagmus syndrome (INS). This...

The clinical spectrum of albinism

The authors sought to examine clinical correlates that may be related to foveal development in albinism with an aim to qualitatively describe the phenotype spectrum of albinism. Binocular best corrected visual acuity ranged from 20/20 to 20/80. Best corrected visual...

Do operative interventions for IIH improve visual function?

The authors of this paper reviewed patient case notes to determine visual outcome following shunt surgery for idiopathic intracranial hypertension (IIH). A retrospective case notes review was conducted for 50 patients who underwent shunt surgery for IIH. Outcome measures included...

Selection of visual field test for detection of pituitary disease

This prospective cross-sectional diagnostic accuracy study compared Octopus semi-automated kinetic perimetry (SKP) and Humphrey static automated central perimetry for detection of neurological visual field loss in patients with pituitary disease. Humphrey central 30-2 SITA threshold programme results were compared with...

Comparing visual acuity to visual demand levels in classrooms

This study investigated the actual logMAR and contrast sensitivity demands in a cross-sectional sample of kindergarten through grade 12 classrooms in New York city. This was done to consider the potential benefit in optimising the specificity of visual acuity-based screening...

Visual outcomes and predictors in optic pathway glioma

This is a retrospective study of 60 paediatric optic pathway glioma (OPG) patients (NF1 or sporadic) presenting to Great Ormond Street between 2003-2017. Median follow-up was 82 months. Analysis was divided into best and worst eye vision representing level quality...

Using bupivacaine to the medical rectus in addition to lateral rectus recession for convergence insufficiency type intermittent exotropia

This is a retrospective study of 60 paediatric optic pathway glioma (OPG) patients (NF1 or sporadic) presenting to Great Ormond Street between 2003-2017. Median follow-up was 82 months. Analysis was divided into best and worst eye vision representing level quality...

Agreeing terminology for non-classic visual field abnormalities

The authors present a prospective survey of neuro-ophthalmologists. The survey comprised of 10 visual fields. The selection of visual fields for the survey aimed for variety and excluded classic neuro-ophthalmology visual field defects, e.g. hemianopia, nasal step. The survey was...

Mast cells in Graves’ ophthalmopathy

Graves’ ophthalmopathy (GO) is a potentially sight-threatening ocular disease, occurring in patients with hyperthyroidism due to Graves’ disease. Also known as thyroid-associated ophthalmopathy, GO is characterised by orbital infiltration by immune cells including macrophages, T cells and plasma cells, which...

European experts working with Royal Blind School on future of vision impairment education

Vision impairment education experts from Germany, Holland and Spain recently visited the Royal Blind School in Edinburgh to create a catalogue of objects that can be 3D printed.

A novel integrated practice unit (IPU) approach to periocular skin cancer management

The COVID-19 pandemic was one of the biggest challenges to face NHS workers. However, history has repeatedly shown that times of difficulty can result in the development of significant social and technological advances. We describe our own experience of this...

Smartphone based visual acuity

Smartphone technology is becoming widely available to all age groups and settings. Apps using Snellen acuity charts are widely available and this study evaluated the equivalence of a smartphone-based visual acuity chart with a standard 6m Snellen visual acuity (6SVA)...
