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...

Association of sleep problems in children with visual impairment

The intention of this study was to investigate sleep problems in children who had a wide range of visual impairments. Recruitment was via an online survey distributed through the National Federation of Blind and National Organisation for Albinism and Hypopigmentation,...

Childhood blindness and visual impairment in the Narayani Zone of Nepal

Up to 50% of childhood blindness is preventable or treatable, and its control is a high priority in the VISION 2020 initiative of the International Agency for the Prevention of Blindness. In this study, the authors utilised the rapid assessment...

Visual retraining for homonymous hemianopia following stroke

This is a clinical trial evaluating the efficacy of motion discrimination training as a potential therapy for stroke-induced hemianopic visual field defects involving 48 patients. They were randomised into two arms, one intervention (deficit-field) and one control (sighted-field). Patients were...

Transient visual loss caused by crowded optic discs

The author presents four cases of transient visual loss (TVL) in young females (age range at presentation 14-22 years) with crowded optic discs. Patient demographics, investigations, medical and social histories are provided for all patients. A review of evidence for...

Visual outcome and surgical results in children with Marfan Syndrome

Eighty-two eyes of 41 patients with a genetically proven diagnosis of Marfan syndrome were retrospectively analysed. Twenty-seven had bilateral subluxation and 14 received lensectomy. Follow-up was three years. Mean visual acuity (VA) was 0.1 ±0.7 logMAR in patients with normal...

Retinotopic fMRI reveals visual dysfunction and functional reorganisation in the visual cortex of glaucoma patients

This study investigated the retinotopic functional representation in the visual cortex of mild to moderate primary open-angle glaucoma (POAG) participants and age-matched normal volunteers, using wide-view visual presentation, high-resolution retinotopic stimuli, and high-resolution blood oxygenation level dependent (BOLD) functional magnetic...

Normative data using a virtual reality game-based visual field test

The authors present a prospective cross-sectional study involving healthy children to assess the use of a virtual reality game-based perimetry assessment. A single eye centre recruited through paediatric optometry and ophthalmology clinics over a 12-month period. Children aged <18 years...

Clinical and neuro-ophthalmologic predictors of visual outcome in idiopathic intracranial hypertension

This prospective study of 40 patients aims to assess visual morbidity in patients with idiopathic intracranial hypertension (IIH). Final visual outcome of patients was compared with clinical and neuro-ophthalmic parameters such as visual acuity, visual field, contrast sensitivity, retinal nerve...

Higher risk of poor functional outcome in the presence of visual deficits post-stroke

The authors present a retrospective case review with the aim of reporting the disability outcomes of individuals 90-days post stroke with and without visual deficits. The Houston Methodist Hospital Outcomes-based Prospective Endpoints in Stroke (HOPES) Registry was used as the...
