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...

Changes in C:D ratio of premature infants with enlarged C:D ratios

This retrospective observational study examined the longitudinal alterations in cup to disc ratio (CDR) among premature infants exhibiting enlarged CDR and normal intraocular pressure (IOP) up to two years. Among the 283 infants, 13.4% manifested an enlarged CDR. In this...

Longitudinal findings in children with neurofibromatosis type 1

This retrospective chart review evaluates the ophthalmologic findings of children with neurofibromatosis type 1 (NF1). Optic pathway gliomas (OPGs) are the most common tumours found in children with NF1. Findings are compared between eyes with and without optic pathway gliomas...

OCT measurements in neurodevelopmental conditions

The authors aimed to investigate what changes occur in the retinal nerve fibre layer (RNFL), ganglion cell layer (GCL) and macula when specific learning disorder (SLD) comorbidity is added to attention deficit hyperactivity disorder (ADHD). They compared measures in three...

Neuro-ophthalmology consequences of Lyme disease

Changes in retinal and choroidal microcirculation after strabismus surgery

The aim was to evaluate retinal and choroidal microcirculation using optical coherence tomography angiography after strabismus surgery. This was a cross-sectional observation study of 44 eyes of 44 patients. Patients were split into three groups: (1) one-muscle horizontal surgery (n=9);...

Aetiology of painful ophthalmoplegia

Painful ophthalmoplegia is a clinical syndrome presenting with periorbital / hemi-cranial pain and ipsilateral ocular motor nerve palsies and can occur with numerous different diseases. In this study, the authors aimed to determine the final definite aetiology among patients with...

QuickSee Free autorefractor results in outreach settings

The Gambia screening project was launched in 2022 to provide vision screening for school-aged children. Within this screening programme, the refractive error measurements of the QuickSee Free autorefractor were compared to cycloplegic refraction in this outreach setting. Six rural schools...

LambdaVision aims to refine process for in-space manufacturing of artificial retinas through ISS National Lab-sponsored investigation

Approximately 1.5 million people worldwide are affected by retinitis pigmentosa, a rare genetic disorder that causes vision loss. Currently there is no cure, but researchers from LambdaVision are turning to the International Space Station (ISS) National Laboratory to look for...
