25 years of OCT

David Huang first described optical coherence tomography (OCT) in 1991, in his seminal paper on the subject in Science. This method developed the work of others on ophthalmic interferometry, which essentially showed that measuring reflected light could be used to...

The embryology of the eye

Nobody claims to like embryology. At least nobody I know. It has been a neglected part of the curriculum since time immemorial and a vicious cycle occurs in which those with an incomplete understanding fail to appreciate the inherent beauty...

Choroid and retinal changes post COVID-19

The authors aimed to evaluate choroid and inner neural layers in people previously recovered from Covid-19 compared to healthy controls using optical coherence tomography (OCT) over a six-month period. They recruited 96 people: 56 with Covid-19 at least three months...

The approach to angle-closure glaucoma

Further to my last article in Eye News (print issue) describing the diagnostic approaches to various clinical scenarios in glaucoma, the approach to angle-closure glaucoma (ACG), a situation terrifying for patient and registrar alike, will be discussed. Please refer to...

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...

Moorfields Education: Hot topics in comprehensive ophthalmology

Hot topics in comprehensive ophthalmology is a course for people who work in the field suitable for comprehensive/general ophthalmologists, urgent care and primary care, optometrists and nurse practitioners. This is an update on common themes which appear in the comprehensive...

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...

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...
