Changes in the choroid after atropine for amblyopic and fellow eyes

The purpose of this study was to compare the effects of atropine on the thickness and structure of the choroid between amblyopic and fellow eyes. This study included 16 patients: five males, 11 females. Median age at ocular coherence tomography...

Ocular damage from laser pointers

This retrospective study of case notes from a tertiary eye centre over a five-year period, recruited nine children (12 eyes: eight boys) aged 9-15 years. Three presented with deteriorating vision whilst others had retinal changes noted as incidental findings at...

Does methanol poisoning require ophthalmic investigation?

The authors report a case series of 21 patients (41 eyes) diagnosed with acute methanol poisoning following an outbreak in Tunisia in 2020. All patients underwent a complete ophthalmological examination including visual fields, colour vision test and optical coherence tomography...

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...

A review of neuro and retinal imaging findings in Alzheimer’s disease

The authors present a systematic review with the aim of assessing the relationship between retinal and cerebral changes in Alzheimer’s disease (AD), mild cognitive impairment and pre-clinical AD. A total of 23 articles met the inclusion criteria of the review,...

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...

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...

Characteristics of cherry red spot on optical coherence tomography

In this study the authors report optical coherence tomography (OCT) characteristics of cherry red spot from three cases of Tay-Sachs and one case of Niemann Pick diseases to determine associated factors and potential visual implications. This was a retrospective case...

Normative reference values for optic nerve sheath diameter in children

The purpose of this study was to measure optic nerve sheath diameter (ONSD) in paediatric patients without pathology using brain CT performed for various reasons and to provide normal tomographic reference values. This was a retrospective study of CT scans...

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),...
