Subconjunctival anaesthesia in vitreoretinal surgery

The authors present a technique that combines topical and subconjunctival anaesthesia for vitreoretinal surgery. In this ‘two-step’ procedure, three drops of proparacaine were applied to the conjunctival fornix, followed by subconjunctival lidocaine injected in three quadrants. This was compared with...

The posterior capsular rupture rate post COVID-19 pandemic

In this retrospective single centre consecutive case series, the authors investigate the effect of suspending elective cataract surgery during the COVID-19 pandemic for a period of 19 weeks. They divided the study period, September 2019 to January 2021, into three...

Long-term outcomes of recess / resect for sensory XT

The purpose of this study was to evaluate relationships between initial and long-term outcome of unilateral recess / resect surgery in adult sensory exotropia, factors associated with long-term outcome, exotropia drift and time to failure follow-up surgery. This was a...

Spot screener versus Grand Seiko measurements

The authors aimed to determine repeatability and reproducibility of refractive values and pupil size measured using the Spot Vision Screener and to compare its measurement values with the Grand Seiko autorefractor. This was a cross-sectional study of 22 healthy adults;...

Outcomes of augmented surgery for exotropia

This was a prospective study to assess patients with basic type intermittent exotropia of 15-45PD in angle and who were operated with augmented bilateral lateral rectus recessions with conjunctival recession, and followed postoperatively for six months. The study included 15...

Effect of observation of intermittent exotropia on health-related quality of life of children and parents

The authors present the analysis of the Intermittent Exotropia Questionnaire (IXTQ) completed by the observation arm of a previously reported randomised controlled trial comparing part-time patching to observation. Children aged >5 years completed the Child IXTQ, and all parents completed...

Visual outcomes after surgery for primary RRD in era of microincision vitrectomy

This is a prospective, multicentre, nationwide study between 2016 and 2017, to investigate the preoperative ocular factors, surgical techniques (pars plana vitrectomy (PPV) or scleral buckling (SB), or combined procedures) for rhegmatogenous retinal detachment (RRD) and postoperative best corrected visual...

A retrospective medical notes review in patients with poor vision due to NAION

Very severe visual loss (hand movements or less) is typical of arteritic anterior ischaemic optic neuropathy (AION) and relatively rare in non-arteritic AION (NAION). This study aimed to report the frequency of very poor visual acuity (VA) in NAION. The...

Using lumbar puncture as a diagnostic tool of IIH when the presentation is typical

The authors present the findings of a retrospective observational chart review across three neuro-ophthalmology clinics. Databases at each clinic were searched using inclusion criteria based on established diagnostic criteria for idiopathic intracranial hypertension (IIH). Cases with missing data, atypical findings...

Accuracy of AS-OCT muscle insertion measurements

Anterior segment - optical coherence tomography (AS-OCT) is a non-contact imaging method that can provide accurate measures of extraocular muscles to limbus insertion distances. The authors evaluated the accuracy of AS-OCT for locating horizontal extraocular muscle insertions after strabismus surgery...

Accuracy of ASOCT muscle insertion measurements

Anterior segment optical coherence tomography (ASOCT) is a non-contact imaging method that can provide accurate measures of extraocular muscles to limbus insertion distances. The authors evaluated the accuracy of ASOCT for locating horizontal extraocular muscle insertions after strabismus surgery in...

ISBCS versus DSBCS

This is a retrospective study of 53 children who had immediate sequential bilateral cataract surgery (ISBCS) (37/53) or delayed sequential bilateral cataract surgery (DSBCS) (16/53) at a tertiary referral paediatric hospital in Toronto, Canada. Clear visual axis was the measure...
