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...

A case series of electroretinography findings in visual snow syndrome

The authors present a case series of individuals referred to an electroretinography (ERG) lab for assessment due to abnormal vision symptoms, over a two year period. Cases with visual snow syndrome (VSS) or isolated visual snow (VS) were included. All...

Tumour characteristics influencing visual field outcomes

This retrospective study aimed to explore correlations between pituitary tumour characteristics which influenced visual field changes. Cases of transsphenoidal surgery from a six-year period resulting in a pathologic diagnosis of pituitary adenoma from a single centre were identified. Individuals were...

Detection of post stroke visual impairment in variety of cohorts

The Impact of Visual Impairment after Stroke (IVIS) study introduced a standardised vision assessment protocol across three acute stroke units in the northwest of England, with a similar demographic population (predominantly white British). The study reported similar rates of visual...

A novel test for unilateral functional visual loss

The authors report results of three cases of functional visual loss, where regular ophthalmic testing was not sufficient to confirm the diagnosis. In these cases, bilateral concurrent eye examination was performed using a head-mounted perimeter (imo), to facilitate the diagnosis....

A case report of visual loss as a consequence of coeliac disease

The authors present a case of permanent visual loss secondary to occipital lobe calcification in coeliac disease, the first reported such case. The 58-year-old man had been diagnosed with coeliac disease 20 years prior to his visual investigations and had...

Visual defects in deaf children and young adults

This literature review article serves as a great update on the current evidence relating to visual defects in the young deaf population. There is a good introduction with background information and demographic data relating to UK hearing impairment. The authors...

Visual field changes in thyroid eye disease (TED)

This study is a retrospective non- comparative review of visual field (VF) tests in patients with compressive optic neuropathy from thyroid eye disease (TED-CON). Ninety-six visual fields in 68 patients were included in the study and a two-step analysis of...

Strabismus surgical outcome with unilateral visual loss

The purpose of this study was to analyse the surgical outcome of strabismus surgery in patients with unilateral visual loss and horizontal strabismus. This was a retrospective review of 21 patients. Nine children were reviewed with a mean age of...

Predicting visual prognosis of patients with methanol poisoning

Symptoms of methanol poisoning often occur 12–24 hours after oral consumption, and visual symptoms are seen in approximately 50% of cases. This study aims to investigate the role of optic nerve diffusion status on cranio-orbital magnetic resonance imaging (MRI) in...

Visual acuity after cataract surgery in AMD patients

The data from this study are obtained from the Age-Related Eye Disease Study (AREDS) 2 and analysed to evaluate if cataract surgery benefits patients with concurrent age-related macular degeneration (AMD). The AREDS 2 was a five year, prospective, multi-centre randomised...

Effective contrast ratio as a measure of binocular visual perception

The authors used a binocular phase combination paradigm to quantitatively evaluate and compare the binocular visual perception of normal individuals and patients with different types of strabismus to understand the binocular visual perception of patients with strabismus and evaluate whether...
