Viral uveitis

This review covers viral causes of anterior uveitis. A viral aetiology should be suspected when anterior uveitis is accompanied by ocular hypertension, diffuse stellate keratic precipitates or the presence of iris atrophy. Most common viruses associated are herpes simplex, varicella-zoster...

Is myopia protective against progression of diabetic retinopathy?

This population-based cohort study assessed the association of refractive error with the incidence and progression of diabetic retinopathy (DR); 1562 eyes of 860 patients with diabetes and gradable retinal photographs were included. Baseline data was taken between 2004-2009 and follow-up...

Microbiology, risk factors and outcomes of microbial keratitis in Sydney, Australia

The authors present a retrospective case series including all patients with microbial keratitis and ocular surface diseases (OSD), including dry eye, blepharitis, Stevens-Johnson syndrome and / or ocular cicatricial pemphigoid, over a five-year period between 2012 and 2016. A total...

Accuracy of intraocular lens power calculations in paediatric eyes

A study comparing the accuracy of the SRK II, SRK/T, Hoffer Q, Holladay 1, T2 and Super formula in predictive refractive outcomes in children undergoing primary IOL insertion into the capsular bag following cataract surgery. A total of 377 eyes...

5-FU in cicatricial conjunctivitis

This is a retrospective review of 56 patients with cicatricial conjunctivitis, including 25 eyes that received sub-conjunctival injections of 25-50mg of 5-fluorouracil (5-FU) as part of their treatment. Thirty-seven patients had ocular cicatricial pemphigoid (OCP) and 19 had Stevens-Johnson syndrome...

Effect of long-term RGP-CL wear on keratoconus progression

This is a retrospective study between April and December 2017, of 22 rigid gas-permeable contact lens (RGP-CL) patients (31 eyes) and 15 non-CL patients (20 eyes) who fulfilled the criteria of: 1) >3 years follow-up and 2) Scheimpflug-based corneal imaging...

Posterior capsular rupture risk factors as reported in the European registry

In this cross-sectional review of the European Registry of Quality Outcomes for Cataract and Refractive Surgery (EUREQUO) including 2,853,376 patients and 31,749 cases with posterior capsular rupture (PCR), the authors observed a trend of reduction in PCR rate from 1.44%...

Are any precautions needed when performing cataract surgery in thrombocytopenic patients?

In this retrospective multi-centre study, charts for 196 eyes of 150 thrombocytopenic patients were reviewed. The mean preoperative platelet level was 73.0 ± 20.5 × 103/μL (median of 76.0 × 103/μL), with a range of 17 to 100 × 103/μL...

Multidrug-resistant keratitis: challenging yet manageable

This is a retrospective review of all patients’ records from a tertiary referral centre in India from January 2018 to December 2019, who had corneal scrapings for direct smear and culture sensitivity. Those cases where the organisms were diagnosed to...

Cadaveric measurements of the Spiral of Tillaux

The authors conducted a cadaveric study to investigate and analyse the variability of the mean distances of the extra-ocular muscle insertion sites from the limbus as well as corneal diameters. The study included measurements taken from 30 white cavaders; 50%...

Simulated ocular surgery

Blame the lens – not its position – in refractive surprise

Aetiology of postoperative refractive surprise Weber coined the term “wrong eye, wrong intraocular lens, wrong patient” in 2008 as an aide memoir of major factors believed to underlie refractive surprise – defined as a significant unintended difference between dioptric refraction...
