Best way to detect glaucoma progression: by reflecting on the past 25 years

Glaucoma – a condition of optic neuropathy leading to progressive visual field loss often associated with raised intraocular pressure. It is fair to say that our definition for this condition has remained unchanged over the last 25 years and the...

Development of testing protocols for high and low contrast visual acuity

Dysfunction of the afferent visual system, characterised by impairments in high-contrast visual acuity (HCVA) and low-contrast visual acuity (LCVA) have been demonstrated in some neurological conditions such as multiple sclerosis and Parkinson’s disease. HCVA and LCVA are also potential quantitative...

Lateral rectus transposition for vertical rectus muscle palsy

This study reports the surgical outcomes of patients with vertical rectus palsy in whom the vertical duction deficit is worse in abduction than in adduction. The procedure involved lateral rectus belly transposition without muscle splitting or disinsertion. The lateral rectus...

Occlusion vs. video gaming for treatment of refractive / anisometropic amblyopia

The authors conducted a comparative study of a novel low-cost video game platform – BarronVision (BV) – with standardised occlusion in the treatment of paediatric amblyopia. BarronVision uses a monocular perception learning approach in which the size of optotypes can...

How does a tablet based stereoacuity test perform in children with normal and abnormal visual acuity?

The authors present a prospective cross-sectional comparison study at a single centre. Paediatric patients attending an ophthalmology outpatient clinic and likely to be cooperative were approached to participate. Participants underwent stereoacuity assessment using the ASTEROID and Titmus tests, usually in...

Addressing medical risk factors for diabetes and understanding the new systemic treatments

As global diabetes figures continue to rise, the importance of reducing the burden of macrovascular and microvascular complications of diabetes has never been so great. By 2025 it is estimated that five million people in the UK will have diabetes...

Anisometropia following cataract surgery and its non-surgical treatment

Current recommendations in the UK advise on wearing any facial covering to prevent the spread of the coronavirus [1]. Whilst this is vital for patient and hospital staff safety, it has led to several changes in the approach to a...

Prediction errors of formulas in optical biometers

This study was conducted retrospectively in a private practice setting. Nine formulas were compared for prediction error (postoperative spherical equivalent (SE) minus, predicted SE calculated by each formula), using two optical biometers (Lenstar – optical low coherence reflectometry (OLCR) and...

Eye Healthcare: 90 Years of Progress

Eye Healthcare: 90 Years of Progress by Patrick Condon is far more than a historical account, it is a deeply personal, thoughtful and richly illustrated journey through the most transformative decades in ophthalmology, told by one of Ireland’s most respected...
