Ultra-widefield fundus autofluorescence

The authors assessed the ease and utility of ultra-widefield fundus autofluorescence (UWF-FAF) in detecting suspected inherited retinal disease in children who were difficult to examine. They aimed to assess the sensitivity of UWF-FAF and UWF-CF (colour fundus) photography and clinical...

Perceptual learning treatment for amblyopia

The authors previously conducted a feasibility study examining the potential benefit of a self-administered at-home use of a tablet-based perceptual learning (PL) game. Visual stimuli were presented in various orientations and spatial frequency in a game-play format. This study evaluates...

Using MRI to assess normal variation in optic chiasm anatomy

The authors present an MRI study including 61 MRI scans using a 1.5 T with slice thickness of 1 or 5mm and the sequence showing the highest resolution of the chiasm. A predetermined set of measurements were taken in a...

FA findings in treatment-naive premature infants

This retrospective study examined fluorescein angiography (FA) images of 162 eyes of 81 treatment-naive infants with retinal vascular immaturity and persistent avascular retina (PAR) despite exceeding postmenstrual age of 60 weeks. Disc diameter (DD), optic disc-to-fovea distance (FD), the length...

Natural history of idiopathic intracranial hypertension depending on incidental or symptomatic presentation

The authors present a large retrospective review cohort of consecutive patients diagnosed or presumed idiopathic intracranial hypertension (IIH) over a three-year period at a single tertiary centre. Patients on medication with a known aetiology for IIH were excluded. The cohort...

Disc-fovea angle measurements for objective cyclotorsion review

The author measured the disc-fovea angle (DFA) in 249 healthy people (81 male, 168 female) as part of a retrospective study of 44 to 70-year-old adults. These were grouped as (1) aged 44 / 45 years, (2) aged 59-70 years,...

Progression of macular atrophy in Stargardt disease

The authors present a study of a cohort of patients with genetically proven ABCA4 gene mutation related Stargardt disease. They aimed to quantify the effect of lesion location and topography on disease progression using fundus autofluorescence imaging. One hundred and...

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...

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),...

Associations between cerebral vascular malformations and retinal venous malformations

The authors present a retrospective medical notes review which aimed to understand associations between retinal venous malformations (RVM) and cerebral vascular malformations (CVM). Cases of known CVM over a four-year period were identified. The data extracted from medical records included...

iPad game for screening of amblyopia

This study investigates the utility of vision screening using an iPad to measure interocular brightness disparity (retinal rivalry) for detecting amblyopia in paediatric populations. Polarised glasses were used to separate binocular stimuli with an interactive video programme. This was a...

The Art of Refractive Cataract Surgery

The Art of Refractive Cataract Surgery is a structured and clinically focused textbook aimed at ophthalmology residents, fellows and surgeons seeking a systematic introduction to refractive cataract surgery. Content is presented in a clear format, with concise sections, and effective...
