Micropulse vs. continuous wave trans scleral diode cyclophotocoagulation in refractory glaucoma

Continuous wave cyclophotocoagulation (CWCPC) delivers continuous high intensity energy to the ciliary body in an attempt to reduce aqueous secretion and hence lower IOP. It is often used as a treatment of last resort due to the potential side-effects of...

Near-infrared autofluorescence to diagnose retinal laser injuries

This retrospective observational case series aimed to assess whether near infrared autofluorescence (NIR-AR) imaging is a useful imaging modality in the diagnosis of hand-held laser retinal injuries. Twelve patients from two centres underwent ophthalmic assessment and retinal imaging including fundus...

Microdroplet and splatter contamination during phacoemulsification in COVID-19 era

Half a millilitre of fluorescein was incorporated into 400ml of balanced salt solution to identify microdroplet and splatter from phacoemulsification to simulate possible COVID-19 contamination. Five porcine eyes were mounted to an ophthalmic mannequin head and two surgeons (height 189cm,...

Medial rectus anatomy in exotropia

This study investigates the differences between extraocular muscles in patients with intermittent exotropia and normal controls regarding muscle fibre arrangement and diameter, and distribution and activation of satellite cells. Fifteen patients were recruited having medial rectus resection surgery. Resection sections...

Care pathway to imaging delays for acute oculomotor nerve palsies

A retrospective chart review is presented with the aim of evaluating arterial imaging in cases of third nerve palsy. The study reviewed patients seen with a suspicion of or a final diagnosis of third nerve palsy over a seven-year eight-month...

Is intracranial pressure affected by the valsalva manoeuvres and exercise?

Idiopathic intracranial hypertension (IIH) is characterised by elevated intracranial pressure (ICP), which leads to optic nerve head swelling and a risk of visual loss. The impact of straining and exercise on ICP regulation is poorly understood yet clinically relevant to...

Treatment of progressive keratoconus

This study aimed to analyse the clinical results of accelerated iontophoresis-assisted epithelium corneal cross-linking (i-ON CXL) to evaluate the risk factors for keratoconus progression after treatment, and the safety and efficacy of re-treatment using epithelium-off CXL protocol in paediatric patients....

Could idebenone by the solution for treating dominant optic atrophy?

Dominant optic atrophy (DOA) is a disease of the retinal ganglion cells, with no current treatment options. In most cases, DOA is caused by a mutation in the OPA1 gene. The aim of this study was to evaluate the effect...

TowardPi Brings Next-Generation OCT/A to the UK

TowardPi, a fast-growing leader in ophthalmic imaging, has entered the UK market with its advanced swept-source OCT (SS-OCT) and OCT angiography (OCTA) systems. Distributed exclusively by Mainline Instruments, TowardPi is already well-established in Asia and is recognised for pioneering the...

Outline of clinical care for healthy newborns with uncomplicated conjunctivitis in the US

The purpose of this study was to explore the current state of clinical care for healthy newborns with uncomplicated ophthalmia neonatorum (ON) using a large electronic health record dataset. Despite the existence of national guidelines for antepartum screening for N....

A brief history of colour vision

Andrew Want takes a look at how colour vision has evolved in humans and animals and how it differs across species. Colour vision is something that we often take for granted, but it has become so intrinsic to the way...

Unravelling ocular motility

Ocular motility can often be a slightly abstract concept during the earlier years of ophthalmology training. A large variance on what embodies normality; mythical concepts like fusion and binocular vision, examination techniques that can be fiddly, and complex neuroanatomy all...
