Retinal nerve fibre layer thickness in migraine

The aim of this study is to evaluate retinal nerve fibre layer (RNFL) thickness changes in children with migraine compared to healthy controls and analyse RNFL changes dependent on type of migraine. This was an observation case control study of...

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...

Overview of issues with provision of paediatric ophthalmology care

Previous reports have summarised a consistent decline in paediatric ophthalmology over the past 20 years with significant differences in mean salary compensation for paediatric ophthalmologists vs. other ophthalmology subspecialties. Many subsidise income by other non-paediatric work or retire early. With...

Choroid and retinal changes post COVID-19

The authors aimed to evaluate choroid and inner neural layers in people previously recovered from Covid-19 compared to healthy controls using optical coherence tomography (OCT) over a six-month period. They recruited 96 people: 56 with Covid-19 at least three months...

Types of nystagmus and associations in a large international database for nystagmus

The authors aimed to characterise a large international cohort of children with nystagmus. Data were taken from a prospective database which was started in 2010. Up to 2020, this contained 1774 patients with nystagmus from 38 US states and 30...

Anti-myelin oligodendrocyte glycoprotein antibody positive optic neuritis: a retrospective medical records review

Optic neuritis causes acute loss of visual function and can result in devastating visual dysfunction. Recently, measurements of anti-aquaporin 4 (AQP4) and anti-myelin oligodendrocyte glycoprotein (MOG) antibodies have become available, making it possible to evaluate the disease pathogenesis. This paper...

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...

A novel parameter for angle closure

This is a population cross-sectional study of 464 eyes that underwent swept-source optical coherence tomography (SSOCT) imaging in the dark. Eight out of 128 cross-sectional images were selected for analysis. Matlab was used to measure the iridolenticular contact area (ILCA),...
