Oral omega-3 fatty acid treatment for dry eye in contact lens wearers
This study evaluates the effect of dietary omega-3 fatty acid supplementation of dry eye symptoms, tear film tests, and conjunctival impression cytology in patients with contact lens wear-associated dry eye. In this randomised double-blind, multi-centred trial, contact lens wearers (n=...Non-arteritic anterior ischaemic optic neuropathy (NA-AION): a review
Ischaemic optic neuropathy (ION) is the commonest adult optic neuropathy encountered today in our ageing population, is a common cause of irreversible visual loss and is usually associated with underlying vascular disease. The condition is classified as follows: (a) Anterior...Insects, swelling and sight loss: a case of orbital inflammatory syndrome
Despite being the most common cause of painful orbital mass in adults and the third most common orbital disease, orbital inflammatory syndrome still proves to be a difficult ocular condition to diagnose, treat, and manage. A 41-year-old lady presented to...Therapy for limbal stem cell deficiency: cell fate after limbal stem cell transplants
“The beauty of scientific research lies in that the search for answers often yields yet more questions.” A large body of evidence points to the corneoscleral limbal location as the repository of putative epithelial stem cells [1]. Thoft proposed the...Decoding the red eye
Red eye, or hyperaemia, is one of the most common presentations to primary care [1] and the emergency department [2]. However, despite this the underlying cause is often misdiagnosed which can lead to severe, sight-threatening conditions being missed [1]. Thorough...
Squamous metaplasia of conjunctival epithelial cells with soft contact lens wear versus non-lens wearers
Conjunctiva is composed of non-squamous epithelial cells interspersed with goblet cells, which is a secretory epithelium. Squamous metaplasia is a transformation to non-secretory epithelium, ‘keratinised’ and enlargement of the conjunctival non-goblet cells and relatively shrunken nuclei are seen on impression...Pituitary adenoma causing compression of the optic chiasm
A 21-year-old girl presented to her general practitioner (GP) with a three-month history of headaches, becoming more frequent and associated intermittent vomiting that did not improve with simple analgesics. There was a strong family history of migraines. She was initially...Quiz Dec/Jan 2023

The first laser was created in 1960 and its name is an acronym for ‘light amplification by stimulated emission of radiation’. Laser technology has been used for medical, industrial, research and entertainment purposes in a variety of fields following extensive...Strengthening capacity for ophthalmic research within three East African VISION 2020 LINKS – The Research Mentorship Workshop
Building capacity for ophthalmic research in low- and middle-income countries is an important aim of the VISION 2020 LINKS Programme. The International Centre for Eye Health (ICEH) at the London School of Hygiene & Tropical Medicine (LSHTM) has been working...Neovascular AMD: fresh recommendations underline standards of best practice
The management of neovascular age-related macular degeneration (nAMD) has advanced dramatically over the past seven years, with the introduction of targeted new therapies that successfully maintain or improve vision in a majority of affected individuals. It’s a fast moving field,...
