Histopathological changes in rabbit retinitis pigmentosa

The authors report the histopathological changes of retinal ganglion cells (RGCs), optic disc and optic nerve in rabbit with advanced retinitis pigmentosa (RP). RP was recreated in rabbits by using bacterial artificial chromosome transgenesis, with the purpose of increasing understanding...

Syndromic V-pattern management

The authors document their experience in the management of four cases of Crouzon syndrome and review the anatomical extraocular muscle anomalies noted during surgery. Horizontal strabismus surgery varied in each of the four cases according to individual extraocular muscle abnormalities...

ABCA1 mediates lipid efflux in the retina

Age-related macular degeneration (AMD) is the leading cause of blindness in the elderly population. There are two forms of AMD, dry and wet, the latter so named because of the presence of choroidal neovascularisation. Both forms lead to retinal pigment...

VEGF and axial length (RVU)

The authors of this paper set out to examine whether the concentrations of VEGF in the vitreous were associated with refractive error and axial length in eyes without retinal disease, except of macular holes or epiretinal membranes. A vitreous sample...

HtrA1 enhances cell senescence

A genetic basis for age-related macular degeneration (AMD) has been greatly advanced in recent years. The role of identified pathways such as complement factor H in AMD has been widely investigated. However, the effect of other gene variants identified by...

Macular pigment and dark adaptation in older population with normal maculas

Macular pigment (MP) such as lutein, zeaxanthin and meso-zeaxanthin are highly concentrated in the fovea. They protect the retina from damage of ambient blue light via antioxidant properties. In older eyes with normal healthy retina, macular pigment optical density (MPOD)...

Delayed angle closure in pseudophakia and repeated intravitreal therapy

The authors report two cases of acute angle closure many years after uneventful cataract surgery and posterior chamber intraocular lens (IOL) implantation. Both patients had neovascular age-related macular degeneration (AMD) and received regular intravitreal injections (24 and 25 injections in...

Risk of CNV related to angioid streaks in PXE

This retrospective cross-sectional study investigated 301 patients with pseudoxanthoma elasticum (PXE) for prevalence of choroidal neovascularisation (CNV) and macular atrophy. Some patients were excluded due to missing or poor-quality imaging or the fact that they didn’t have angioid streaks, leaving...

Changes in drusen and retinal layer volumes prior to CNV development

This retrospective longitudinal study looked at patients with wet age-related macular degeneration (AMD) in one eye who subsequently developed wet AMD in the fellow eye. The aim was to discover whether drusen characteristics or volumes of retinal layers correlate with...

Aflibercept (AF) for age-related macular degeneration (ARMD): four-year outcomes of a ‘’treat-and-extend’ (T&E) regimen with exit-strategy

This is a retrospective observational study of 82 patients, between 2014 to 2016 from Switzerland of treatment-naive patients with nARMD, treated with AF, with specific T&E protocol without a loading phase and predefined exit criteria and patients were observed three...

The use of virtual reality in paediatric ophthalmology

The purpose of this study was to investigate the utility of virtual reality (VR) in the broader field of paediatric ophthalmology with review of examination, screening, diagnosis, prevention and treatment. This review also explores the potential of eye tracking used...

Ophthalmic viscoelastic devices: Useful insights for a novice cataract surgeon

Ophthalmic viscoelastic devices (OVDs) are essential in many different stages of cataract surgery. This article discusses the categories of OVDs and their respective properties, and highlights their uses in different scenarios faced in cataract surgery. Ophthalmic viscoelastic devices are gel-like...
