Stereotactic radiotherapy for polypoidal choroidal vasculopathy

Polypoidal choroidal vasculopathy (PCV) is a variant of neovascular AMD. It is a disease of choroidal vasculature characterised by abnormal branching vascular network with aneurysmal dilatations (polyps). Features of PCV include pigment epithelial detachments (PED), subretinal fluid (SRF) accumulation and...

Myopic choroidal neovascularisation

This is a review article summarising the latest myopic CNV (choroidal neovascularisation) literature in the clinical experience and management outcomes for recommendation algorithm. The aetiology of the myopic CNV was discussed by the authors under the heading of the heredo-degenerative...

Transfected RPE cells inhibit AMD in rats

Age-related macular degeneration (AMD) is a leading cause of blindness in the elderly. Wet AMD is characterised by choroidal neovascularisation, new vessels into the retina, leading to leakage and tissue damage. Many proangiogenic factors particularly vascular endothelial growth factor (VEGF)...

Aqueous humour cytokine levels in PCV and nAMD

This study looks into the possible roles of various cytokines or growth factors in the pathogenesis of exudative age-related macular degeneration (AMD) by comparing aqueous levels of 14 cytokines between eyes with polypoidal choroidal vasculopathy (PCV) and those with neovascular...

Progression of myopic maculopathy after treatment

The authors report on a retrospective study carried out to evaluate long-term progression of myopic maculopathy and functional outcome in eyes treated for myopic choroidal neovascularisation (CNV) and in eyes without CNV. Fifty-four myopic eyes of 30 patients were included...

Multimodal imaging in wet AMD

This novel study set out to determine grader agreement levels of various retinal imaging techniques, commonly used in the diagnosis of wet age-related macular degeneration (AMD). Images from 52 eyes were by examined by two different observers. All images were...

Aflibercept treatment in polypoidal choroidal vasculopathy

The authors present a study to evaluate the anatomical and functional efficacy of aflibercept intravitreal (IVT) as a monotherapy in polypoidal choroidal vasculopathy (PCV) in a Caucasian population treated with initial three-monthly aflibercept IVT, followed by a bimonthly regimen for...

Retinoblastoma management update (part 1): clinical features, diagnosis and genetics

The first of a two part series, this article will discuss the clinical features, diagnosis and genetic aspects of retinoblastoma. Manoj Parulekar is based at Birmingham Children’s Hospital, one of the two designated national retinoblastoma and paediatric ocular oncology treatment...

Optical coherence tomography – reinventing the eye examination

It has been 25 years since Huang et al. presented the first optical coherence tomography (OCT) images in Science [1]. With vast improvements in OCT technology over the years, it is now possible to acquire high-resolution cross-sectional images of the...

Effects of blood donation on the physiology of the eye

Hypovolaemia is a state of decreased blood volume, the reduction of which reduces tissue perfusion which may in turn lead to cellular hypoxia and end-organ damage. In blood donation, 500ml of blood is collected in ten minutes. This equates to...

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...

Glaucoma diagnosis after paediatric cataract surgery

The authors undertook a retrospective review of patients with glaucoma after congenital cataract surgery and report clinical presentation, treatment and long-term outcomes at a tertiary referral centre. The study included 58 eyes of 42 patients of which 59% were male....
