AI predicts eye damage from autoimmune drug, years before symptoms appear

A novel AI tool could transform screening for patients taking hydroxychloroquine by spotting early signs of eye damage, according to a study published in Opthalmology Retina. Researchers have devised an artificial intelligence (AI) system that can detect and predict serious...

Effect of oxygen levels on binocular summation of dark vision

Previous studies have reported conflicting results on the existence of binocular enhancement of dark vision. This study compares monocular and binocular absolute thresholds of dark adaptation in two different populations (healthy individuals and those with chronic respiratory insufficiency). The study...

Comparison of vision screeners

The primary purpose of this study was to calibrate the various paediatric photoscreeners over a range of contact lens induced hyperopic and astigmatic anisometropia using the American Association of Paediatric Ophthalmology and Strabismus (AAPOS) criteria for anisometropic or axial astigmatism....

Randomised controlled trial for large-angle exotropia surgery

The purpose of this study was to investigate single eye, single setting surgical options to correct 80–90PD of exotropia with two options of muscle transplant and suture hang-back recession. There was retention of anatomical limits of 6mm resection for medial...

Predictors of IOP reduction after SLT

The aim of this study was to identify predictors of intraocular pressure reduction following selective laser trabeculoplasty (SLT) in patients with primary open-angle glaucoma, who are already taking maximally tolerated IOP-lowering medication and need further IOP reduction. In this prospective...

Risk calculation variability over time in OHT

In this study the authors aimed to assess the variability of the well documented risk model from the Ocular Hypertension Treatment Study (OHTS) that identified higher intraocular pressure (IOP), older age, lower central corneal thickness (CCT), greater vertical cup-to-disc ratio...

One-year result of XEN45 implant for glaucoma: efficacy, safety, and postoperative management

The authors report a retrospective, non-randomised interventional case series of 39 patients who underwent a standalone XEN45 implantation. All 39 patients (female: male=1.2: 1) completed 12-month follow-up. Mean age was 70.1 years (range 32–92). Primary outcome measures were the intraocular...

Medial rectus inferior half plication surgery for near exotropia

In this study the authors report a relatively new surgical treatment for near exotropia. The study included 17 patients: four with previous surgery and all with medial rectus injection of bupivacaine to reduce the angle of deviation. Treatment involved inferior...

100 years of insulin

*Joint first authors The centenary of the discovery of insulin is a time to celebrate one of the most significant scientific discoveries of the 20th century. Background Before 1923, Type 1 diabetes mellitus [T1DM] resulted in death from severe ketoacidosis...

Normal videonystagmography data

The authors report on the smooth pursuit and saccadic eye movement waveforms elicited from normal patients while viewing standardised calibrated targets. Serial trials were performed on each patient to determine test / retest reliability: nine trials producing 117 results by...
