Whiteboard illustrations added to pre-surgery timeout procedure

The authors present results of a quality improvement initiative. A whiteboard illustrated with right and left eyes with views of the extraocular muscles was developed, the board also contained spaces for the patient’s name, deviation, versions and the procedure name....

Retinal traction during ERM peeling

This prospective study aimed to quantify the retinal thickening induced by epiretinal membrane (ERM) peeling and to correlate this thickening with postoperative retinal function. Twenty-five patients who required surgery for idiopathic ERM were included in the study. The authors performed...

Retinal changes prior to hydroxychloroquine toxicity

In this retrospective longitudinal study, the authors examined changes in retinal layer thickness in patients taking hydroxychloroquine without evidence of retinopathy. Patients were drawn from a hydroxychloroquine screening clinic and required at least two OCT scans, at least one year...

Outcomes of treat & extend ranibizumab in diabetic macular oedema

This study retrospectively evaluated 118 eyes of 87 patients who received ranibizumab in a treat and extend regimen for diabetic macular oedema (DMO). Data were collected for patients under follow-up for 24 months. After 24 months, patients gained a mean...

Case reports of ‘ictal lid saccades’ and ‘ictal blinks’

The authors present two cases of lid movements with discrete physiology and propose the terms ‘ictal lid saccades’ and ‘ictal blink’ to describe the movements seen. These two types of lid movement, blinks and saccades, have discrete kinematic properties and...

Factors leading to loss to follow-up after strabismus surgery in children.

One hundred and fourteen patients were identified as lost to follow-up between 2014 and 2020, representing 16% of paediatric strabismus surgery performed during this time period. The authors specifically defined lost to follow-up as not attending follow-up appointments between three...

Occult central retinal artery occlusion

Central retinal artery occlusion (CRAO) is a sight-threatening condition resulting from occlusion of the central retinal artery and hypoperfusion of the inner retina. Early on, fundal examination may be normal. The authors present a retrospective case series of 11 patients...

IOL power in short eyes

Prospective analysis of 269 eyes of 269 patients between 2017 and 2020, with axial length (AL) of 22mm or less. New principles for calculating IOL power were recently developed, including formulas based on paraxial ray-tracing (Barrett and Olsen) and based...

Cystoid macular oedema following retinal detachment surgery

There are limited studies examining the incidence and risk factors for postoperative cystoid macular oedema (CMO) following rhegmatogenous retinal detachment (RRD) repair. Postoperative CMO is thought to be due to pro-inflammatory state, where numerous cytokines lead to tight junction dysfunction,...

Foveal displacement after macular hole surgery

Previous studies show that internal limiting membrane (ILM) peeling during macular hole surgery is associated with retinal shrinkage (microtubule depolymerization of the axons of the inner retina) and nasal shift of the fovea. A temporal inverted ILM flap technique was...

Care journeys of patients with central retinal artery occlusion

The authors present a retrospective case note review of all adult patients referred for or diagnosed with central retinal artery occlusion (CRAO) to a single tertiary hospital over a 10½ year period. A total of 181 patients were included in...

VA and stereo changes with increasing Bangerter filters

This study investigated the effect of monocular blur induced by Bangerter filters (BF) on both monocular and binocular visual acuity (VA) and stereoacuity in normal visual systems. Subjects included 24 healthy student volunteers aged 20.33 ±1.79 years; 22 female. One...
