IOP reduction and progression of high myopic glaucoma

This retrospective study of 131 eyes with high myopia (refraction >-6.0 dioptres or axial length >26mm), best corrected vision 20/40 or better, open angle and follow-up period of more than five years, were included from Korea. Based on the intraocular...

Retinal nerve fibre layer thickness in migraine

The aim of this study is to evaluate retinal nerve fibre layer (RNFL) thickness changes in children with migraine compared to healthy controls and analyse RNFL changes dependent on type of migraine. This was an observation case control study of...

The madarosis mystery: unravelling the clues to a host of health issues

Eyelash madarosis is a medical condition characterised by the loss of eyelashes caused by the destruction of hair follicles. It can range from a few missing lashes to a complete absence of lashes on the eyelids. This condition can be...

Eyes on Rwanda: Lessons from an international ophthalmology experience

On the 26 February 2025, I travelled to Rwanda on the invitation of a former Belfast trainee, Michael Mikhail. Michael is now one of only two vitreoretinal (VR) surgeons in Rwanda, a country with a population of 14 million. Born...

Delayed angle closure in pseudophakia and repeated intravitreal therapy

The authors report two cases of acute angle closure many years after uneventful cataract surgery and posterior chamber intraocular lens (IOL) implantation. Both patients had neovascular age-related macular degeneration (AMD) and received regular intravitreal injections (24 and 25 injections in...

Advances and developments in medical retina

The author provides an update on late breaking clinical trial results in neovascular age-related macular degeneration (nAMD) and presentations on diabetes management from the American Academy of Ophthalmology Retina Subspecialty Day, held during the Academy’s annual meeting in Chicago, October...

Bovine pericardium scleral patch graft associated scleritis: Ahmed valve implant for pupillary block glaucoma

Processed bovine pericardium is a lyophilised collagen sheet used as a surgical armamentarium. It renders the material antigenically inert with minimal inflammation [1]. Sclera patch pericardium graft (Tutopatch) is a collagenous membrane derived from solvent preserved, irradiated bovine pericardium [2]...

Can OCT predict Alzheimer’s disease?

Simerdip Kaur takes a look at the latest ophthalmology-related news stories and asks which are based on facts and which are ‘fake news’. Headline: Can OCT predict Alzheimer’s disease? In 1986 Hinton et al. demonstrated evidence of optic nerve degeneration...

OCT changes in chronic optic neuropathy

The authors evaluated optical coherence tomography (OCT) angiography in 10 patients who suffered various types of chronic optic neuropathies. Glaucoma is known to cause a decrease in peripapillary perfused capillary density on OCT angiography. However, other optic neuropathies have not...

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...

Clinical and neuro-ophthalmologic predictors of visual outcome in idiopathic intracranial hypertension

This prospective study of 40 patients aims to assess visual morbidity in patients with idiopathic intracranial hypertension (IIH). Final visual outcome of patients was compared with clinical and neuro-ophthalmic parameters such as visual acuity, visual field, contrast sensitivity, retinal nerve...

Macular pigment and dark adaptation in older population with normal maculas

Macular pigment (MP) such as lutein, zeaxanthin and meso-zeaxanthin are highly concentrated in the fovea. They protect the retina from damage of ambient blue light via antioxidant properties. In older eyes with normal healthy retina, macular pigment optical density (MPOD)...
