Comparison of bupivacaine injection vs. mini-tenotomy for small angle deviations

Bupivacaine hydrochloride is an aminoacyltype local anaesthetic. Injection into extraocular muscles elicits a myotoxic response destroying striated muscle fibres but sparing satellite cells, nerves and vessels. Preserved satellite cells proliferate to form new muscle fibres, causing muscle hypertrophy and greater...

Test retest values for TNO, Frisby, Lang stereopad and Asteroid stereoacuity tests

This study aimed to determine test-retest variability of four different measurements of stereoacuity including TNO, Frisby, Lang stereopad and Asteroid, and compare stereoacuity values between tests in an adult population. Participants were >18 years of age (mean 38 years, SD...

Increase in myopia during the Covid-19 lockdown periods

The aim of this study was to examine the effect of the Covid-19-related lockdown on myopia progression of school-aged children in Lebanon. The authors reviewed 443 records of myopic children aged 3–18 years (mean 11.81 ±3.67) presenting from January 2020...

A modified technique for external DCR

The authors described a modified technique for external dacryocystorhinostomy (DCR) whereby the lacrimal sac is excised medially along its length using a 15mm blade. Following insertion of silicone stents, the remaining part of the anterior wall of the lacrimal sac...

Choroid and retinal changes post COVID-19

The authors aimed to evaluate choroid and inner neural layers in people previously recovered from Covid-19 compared to healthy controls using optical coherence tomography (OCT) over a six-month period. They recruited 96 people: 56 with Covid-19 at least three months...

Rate and predisposing factors for post-vitrectomy cataract formation in children

This study was a retrospective analysis of post-vitrectomy cataract formation in the general paediatric population. The authors aimed to determine the number of phakic children needing cataract surgery after vitrectomy surgery and related perioperative factors. The study was a 10-year...

Stargardt disease in a Turkish cohort

The authors present a study of 27 Turkish patients who were seen in a single centre over a five-year period. All patients had macular optical coherence tomography (OCT), colour fundus photography and 30-2 Humphery visual fields performed, along with clinical...

Repeat corneal collagen cross-linking after failure of primary cross-linking (CXL) in keratoconus

This is a 10-year, retrospective, patients record review from Leeds, UK. Twenty-one eyes had repeated CXL and the mean interval between primary and repeat CXL was 47.1 months. Twenty (95%) eyes stabilised after repeated CXL at a mean follow-up of...

Paediatric ophthalmology five-year results of atropine 0.01% efficacy in the myopia control in a European population

This a prospective, randomised and longitudinal study from Madrid, Spain in 361 eyes from 361 children randomised into the control group (177 eyes with no treatment) and the treatment group (184 eyes with 0.01% atropine drops once daily). Complete eye...

Atopic dermatitis: Risk of glaucoma progression?

This population-based retrospective cohort study from December 5, 2003 to December 3, 2018 examined 528,469 patients with glaucoma with a diagnosis of atopic dermatitis (AD) based on diagnostic claim codes from the TriNetX Research Network, which contains real-time information on...

OCT measurements in neurodevelopmental conditions

The authors aimed to investigate what changes occur in the retinal nerve fibre layer (RNFL), ganglion cell layer (GCL) and macula when specific learning disorder (SLD) comorbidity is added to attention deficit hyperactivity disorder (ADHD). They compared measures in three...

A novel parameter for angle closure

This is a population cross-sectional study of 464 eyes that underwent swept-source optical coherence tomography (SSOCT) imaging in the dark. Eight out of 128 cross-sectional images were selected for analysis. Matlab was used to measure the iridolenticular contact area (ILCA),...
