Topography-guided photorefractive keratectomy in the treatment of corneal scarring

This study reports the outcome of topography-guided photorefractive keratectomy (TG-PRK) in the treatment of patients with corneal scarring. A retrospective case series including six eyes of six patients with corneal scarring and irregular astigmatism who underwent topography guided PRK. The...

Retreatment of myopic LASIK with femtosecond and custom ablation

The purpose of this study was to identify the risk factors for retreatment post laser in situ keratomileusis (LASIK). A retrospective chart review was carried out for a four-year period and all patients who had undergone LASIK at the Boston...

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...

Accelerated (9mW/cm2) corneal collagen cross-linking for keratoconus

This is one of many studies published / to be published on corneal collagen cross-linking that has a treatment time of 10 minutes compared to the previous Dresden protocol of 30 minutes to halt progression of keratoconus. Much has changed...

Cost-effectiveness framework discussion for vision screening

The authors present a discussion paper on hypothetical, but representative, examples of post-referral costs that may result from different screening options up to the point of discharge from specific services. Data was taken from a recent (2019) systematic review (with...

Leber’s hereditary optic neuropathy: from lab to clinic

Leber’s hereditary optic neuropathy (LHON) was the first clinically described mitochondrial disorder (1871). This article reviews the pathophysiology and clinical features of LHON with a focus on translational research. G11778A is currently the most common mutation worldwide and is associated...

Vision screening standards for fitness to drive

Most countries require that vision meets a pre-defined standard in order to be legally permitted to drive, but these standards vary widely. The primary method by which vision is assessed to determine suitability for driving is by measuring visual acuity...

Cost-effectiveness of femtosecond cataract surgery

Femtosecond laser-assisted cataract surgery has become increasingly popular due to the reported benefits of increasing precision and reproducibility of capsulorrhexis, less power and manipulation required during phacoemulsification, better corneal wound architecture, and the ability to place precise arcuate keratotomy incisions...

The Makassar-Dundee VISION 2020 LINK: a tale of two cities and two trainees

A resident’s view from Makassar My name is Hendra Kusuma, a final year resident (registrar) in the ophthalmology department at Hasanuddin University in Makassar, Indonesia. We have had a VISION 2020 LINK with Dundee (coordinated at the UK end by...

A case of Miller Fisher Syndrome and bilateral asymmetric globe retraction

Miller Fisher syndrome (MFS) is a rare, acquired nerve disease that is considered to be a variant of Guillain-Barré syndrome. It was first recognised by James Collier in 1932 as a clinical triad of ataxia, areflexia and ophthalmoplegia. Later, it...

Advances in the understanding, diagnostic and treatment of keratoconus

*Joint first authors Keratoconus is a bilateral and asymmetric eye condition in which the cornea’s structure is affected and thinned, causing a cone-shaped bulge to develop. This results in progressive loss of vision and impairs the ability of the eye...

Clinical features of basic acquired nonaccommodative esotropia requiring surgery

Basic acquired nonaccommodative esotropia (BANAET) is a concomitant esotropia occurring after the age of six months without significant refractive error or accommodative element. Esotropia is similar for both near and distance and children have prior binocular single vision. The purpose...
