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...

Non-arteritic anterior ischaemic optic neuropathy in the Asian population

This article provides an evaluation of changes in visual function associated with non-arteritic anterior ischaemic optic neuropathy (NAION) among Korean patients. Visual changes were identified as a reduction in visual acuity by three Snellen lines or a deterioration of visual...

Macular thickness and visual fields

The authors describe a comparison of spectral domain OCT with Humphrey visual fields (HVF) mean deviation (MD) and pattern standard deviation (PSD), examining the retinal thickness of the macula and circumpapillary retinal nerve fibre layer (RNFL) defects. Seventy-three subjects who...

Outcomes of corneal cross-linking in paediatric patients compared to fellow untreated eyes

This retrospective cohort study evaluated long-term visual, refractive, topographic and safety outcomes of corneal cross-linking (CXL) in patients younger than 18-years-old with keratoconus. The study included all consecutive paediatric patients who underwent epithelium-off CXL treatment for keratoconus at the study...

Corneal thickness in patients with diabetic peripheral neuropathy

This cross-sectional study assessed corneal thickness in association with diabetic peripheral neuropathy (DPN) severity. The study also tried to identify the layer of the cornea most affected by DPN status. Performed at the University of Michigan the study included three...

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...

Expert vs. non expert grading of ROP from digital video images

The primary purpose of this study was to determine whether digital video images of the retina obtained using an indirect ophthalmoscope imaging system could be accurately graded for zone and stage of retinopathy of prematurity (ROP) and the presence of...

Combined anti-VEGF and PDT for wet AMD

The authors report on a retrospective case series of combined anti-VEGF and photodynamic therapy (PDT) in the treatment of wet age-related macular degeneration (AMD) refractory to anti-VEGF monotherapy alone. The criteria for treatment failure of anti-VEGF monotherapy were persistent subretinal...

First systematic review of COVID-19 colonisation of ocular tissues and secretions

The authors present the first systematic review summarising all the data regarding SARS-CoV-2 colonisation of ocular and periocular tissues and secretions. They reviewed all publications between December 2019 to April 2020 in the Cochrane Library, Medline, World of Science and...

Recurrent sebaceous gland carcinoma

In this retrospective case review study, authors report their outcomes in management of recurrent sebaceous gland carcinoma (SGC) and propose a graded protocol to manage these entities. All consecutive cases of SGC from January 2004 to December 2017 at the...

Amblyopia prediction using Plusoptix

The aims of this study were to evaluate Plusoptix performance in amblyopia prediction, to examine the best readings for that prediction and to determine if it is sufficient to have one measure or more. Data were collected in a two-year...

Outcomes of early versus late surgery for infantile esotropia

The authors aimed to provide a better understanding of the clinical spectrum of infantile esotropia by comparing motor and sensory results in the long-term follow-up of patients who underwent surgery. This was a retrospective review over a 17-year period. There...
