Gene therapy for inherited retinal disease: the Manchester Ocular Gene Therapy Group MDT service

The authors describe the process set up in Manchester for the optimum delivery and assessment of a new gene therapy treatment for patients with RPE65 IRD. Inherited retinal dystrophies (IRDs) are the second commonest cause of severe visual impairment in...

An unusual case of acute retinal necrosis

Case report A 40-year-old Caucasian male presented with a four-day history of redness and progressive painless reduction of vision in the left eye. His visual acuities were 6/4 in the right and 6/36 in the left. The left eye showed...

An update on idiopathic intracranial hypertension

The incidence of Idiopathic intracranial hypertension (IIH) is increasing, likely in line with the worldwide epidemic of obesity. To date, there have been revisions in the terminology used and diagnostic criteria for IIH; these recognise the need to exclude secondary...

Intravitreal Bevacizumab for the prevention of postoperative proliferative vitreoretinopathy in high-risk patients

This single- centre observational retrospective study was conducted to evaluate the effect of intravitreal injection of bevacizumab at the time surgery for rhegmatogenous retinal detachment (RRD) repair on postoperative proliferative vitreoretinopathy (PVR) in patients at high risk selected by laser...

DISC lens slow myopia progression in Hong Kong Chinese schoolchildren

This is a prospective double-blind randomised trial between September 2007 and October 2009. It included 221 children aged 8-13 years, with myopia between -1 and -5 Dioptres ≤1.00D. There were 111 patients in the defocus incorporated soft contact DISC group...

Periocular sweat gland carcinomas

This is an interesting review of a rare group of tumours which together comprise the adnexal sweat gland carcinomas. Although there are only 22 patients, this is the largest cohort ever published. The authors summarise the clinical presentation, stage, management...

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...

Effect of refractive corneal surgery on IOP and glaucoma progression

Accuracy of intraocular pressure (IOP) measurement depends on the biomechanical properties of the cornea, including its thickness central corneal thickness (CCT) and keratometry (K). Fifty-six eyes of 56 patients with primary open angle glaucoma (POAG) who had a history of...

The ‘art’ of refraction – designing a refraction course

Learning how to refract requires theoretical knowledge, practice and determination. Refraction is a notoriously challenging skill to acquire and the competing demands on junior ophthalmologists can often be restrictive of the development of this core skill. To consolidate theory learnt...

A case of retinal cavernous haemangioma – don’t let it slip through the grapevine

We present a case of a seven-year-old male who presented to the emergency eye referral clinic with red eye. He was diagnosed and treated for allergic conjunctivitis, however, on clinic review, wide field retinal imaging was performed (as has been...

Evaluation of keratometry with a novel colour LED corneal topographer

The Cassini topographer (i-Optics), which analyses corneal shape based on the reconstruction of specular reflections on 679 coloured LEDs, generates keratometry and is the new machine being compared in this study with other keratometry devices. The prospective comparative study included...

Telemedicine strategies in ophthalmology: harnessing established and emerging technologies for lasting solutions

The author considers recent progress and shares insights from leading practitioners in telemedicine applications and digital technology strategies. Amidst COVID-19 and combined mitigation and suppression measures, hospitals and clinics have responded rapidly to strengthen telemedicine strategies and virtual healthcare services...
