Imagination

"Logic will get you from A to B. Imagination will take you everywhere.” In this quote by Albert Einstein, he reminds us that whilst logic is useful for practical solutions, the expansive nature of imagination breaks boundaries. It can lead...

NYU Langone Health performs world’s first whole-eye & partial-face transplant

Landmark whole-eye transplant is a major paradigm shift for potential vision therapies.

Spot screen versus cycloplegic refraction

This study compared the spherical, cylindrical and spherical equivalent values obtained by the Spot screener before and after induction of cycloplegia with the values of cycloplegic refraction to explore the application value of the Spot screener in refractive error screening...

DIY IOP – does it work?

Measuring intraocular pressure (IOP) plays a major role in glaucoma care as IOP is a parameter, along with visual field progression and optic disc cupping used to assess treatment effect. While Goldmann tonometry (GAT) is the gold standard, it only...

Comparison of false-negative responses in glaucoma patients and normal observers

The authors compared false negative rates for full threshold (FULL) and Swedish Interactive Threshold Algorithm (SITA) standard automated perimetry in healthy control subjects and glaucoma patients. Twenty-four subjects underwent visual field testing of one eye five times within six weeks...

AC/A non-linearity

This study investigated whether or not the response accommodative convergence to accommodation (AC/A) ratio in 30 visually normal subjects is linear with lens presentation order counterbalanced. Accommodative response was measured using the Shin Nippon SRW 500 infrared autorefractor. Accommodation was...

Comparison of methods of central corneal thickness measurement in glaucoma

This prospective study was done to compare the accuracy and reproducibility of central corneal thickness measured by hand-held and disc-mounted ultrasound pachymeter in glaucoma patients. Sixty-five patients were included in the study. Patients with corneal diseases, corneal astigmatism >3 diopters...

Idebenone for Leber hereditary optic neuropathy

The authors present a meta-analysis of studies reporting the effects of idebenone treatment on visual acuity (VA) in patients with Leber hereditary optic neuropathy (LHON), the most common inherited mitochondrial disorder. They included randomised controlled trials, non-randomised controlled trials and...

Randomisation, confounding & observational methods in ophthalmic epidemiology

Randomisation and confounding Understanding the relationship between an exposure and an outcome of interest is the central challenge in ophthalmic epidemiology. The exposure may be aetiological, taking the form of a putative risk biological factor, or therapeutic, in the form...

A paediatric case of central retinal artery occlusion following antibiotics and decompression surgery for orbital cellulitis

Orbital cellulitis is an ophthalmic emergency that warrants urgent management in the hospital setting [1]. This occurs more frequently in the paediatric population where it is often secondary to sinus infections. Delay in treatment could result in severe complications including...

Refraction under GA in children using cycloplegic refraction as a reference

The authors aimed to compare the measurements of cycloplegic refraction and refraction (R1-1) under general anaesthesia (GA) with automated refraction (ARF) in paediatric patients and to determine the impact of GA on accommodation. The study included 222 eyes of 222...

UK’s leading sight loss charity, RNIB, appoints five new trustees

The Royal National Institute of Blind People (RNIB) has appointed five new trustees to its board. The new additions bring a wealth of experience and will play a crucial role in making major decisions that affect the charity and its...
