Embryology in clinical practice

The fascinating world of embryology is both beautiful and practical. It is a home video of our evolutionary history through the ages from the single cell through to the life aquatic, the development of gut, limbs and brain, and most...

Melanocytoma of the optic disc

Melanocytoma is a heavily pigmented lesion, composed of melanocytes and is a variant of melanocytic naevus. It classically occurs at the optic disc and is usually benign, static and asymptomatic. However, it can occasionally grow and invade the retina or...

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,...

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...

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...

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...

Nicotine accelerates diabetes induced retinal changes

This study investigated the influence of nicotine in an experimentally induced diabetic rat model. They used non-invasive high-resolution spectral domain optical coherence tomography (SD-OCT) imaging to provide quantitative information on the temporal alterations of retinal structures at the micrometer resolution...

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...
