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...

A mouse model for uveal melanoma

Uveal melanoma (UM) is the most common malignant tumour arising within the eye and is a severe threat for both sight and life, due to a high risk of metastasis. There are no animal models of UM, but the Tg(Grm1)...

Complement factor B polymorphism and the phenotype of early age-related macular degeneration

The relationship between complement factor H (CFH) and age-related macular degeneration (AMD) is very well known, but other genetic polymorphisms relating to AMD are more poorly understood. This study was designed to investigate the relationship between complement factor B (CFB)...

Reduction of severe visual loss and complications following IAC for RB

This was a retrospective cohort study of patients with retinoblastoma (RB) who required intra-arterial chemotherapy (IAC) between 2013 and 2015, who had relapsed following systemic chemotherapy. A total of nine patients were included in the study and their ocular complications...

Risk factors and untreated POAG

The authors examined 50 untreated open angle glaucoma patients to determine if there was an association between the level of glaucomatous damage and documented risk factors. In this study the authors measured the extent of morphologic and functional glaucomatous damage...

Lacquer cracks

The purpose of this Japanese study was to analyse the morphologic features and natural progression patterns of lacquer cracks (LC). The presence of linear hyperfluorescence on the fundus fluorescein angiography (FFA) was used as the standard for diagnosing the presence...

A prospective trial of adjuvant therapy for high-risk melanoma

Patients diagnosed with iris, ciliary body or choroidal melanoma of high-risk tumour cytogenetics (monosomy 3>/= 20% of cells), were treated with adjuvant low-dose dacarbacine (DTIC) and interferon –alpha-2b (IFNA-2b), following primary treatment (enucleation, brachytherapy or resection). DTIC was given intravenously...

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...

Orbital cavernous haemangiomas

This is a review of orbital cavernous haemangiomas (orbital cavernous venous malformations) managed over a 12-year period at a tertiary referral centre. Painless proptosis was the commonest presentation. One hundred and sixty-four patients (96 female and 68 male) underwent surgery...

Augmented trabeculectomy with mitomycin C in primary congenital glaucoma

This study aimed to determine success of trabeculectomy augmented with mitomycin C (MMC) in children with primary congenital glaucoma (PCG) and document complications of this intervention. Over a two-year period, the authors treated 74 eyes of 42 children with PCG,...

Macular pigment in relatives of AMD patients

Blue light causes photo-oxidative retinal injury and macular pigment (MP), with lutein, zeaxanthin and mesozeaxanthin as the main components, as a filter that protects the macula from this damage. Previous studies indicated that low levels of macular pigment optical density...

In conversation with Professor Usha Chakravarthy (2018)

Professor Chakravarthy popped by the Eye News stand at the 2018 Royal College of Ophthalmologists Annual Congress after her excellent Bowman Lecture. She gave us a summary of her presentation, which looked at how our understanding of AMD has changed...
