Are corneal guttata an additional risk factor in complicated cataract surgery needing a future corneal transplant?

This registry-based cohort study from Sweden utilised data from the Swedish National Cataract Registry and the Swedish Cornea Transplant Registry. Patients who underwent phacoemulsification with a posterior intraocular lens between 2010 and 2012 numbered 192,476. Of these cases, 288 underwent...

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...

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%...

Polymerase chain reaction evaluation of infectious multifocal serpiginoid choroiditis

This paper presents a retrospective review of infectious agents associated with multifocal serpiginous choroiditis (MSC) based on polymerase chain reaction (PCR) evaluation and specific antimicrobial therapy. The study included 13 patients with MSC who were evaluated with PCR for the...

Clinical predictors of proliferative sickle cell retinopathy

Sickle Cell Disease (SCD) is an inherited disorder resulting in production of Haemoglobin S (HbS), which aggregates in conditions of hypoxia, acidosis or hyperosmolarity. This leads to vascular stasis, thrombosis and ischaemia. The authors present a cross-sectional study (45 consecutive...

Reattachment rate with pneumatic retinopexy vs pars plana vitrectomy for single break rhegmatogenous retinal detachment

This is a post-hoc analysis of two clinical trials, including patients who underwent pneumatic retinopexy (PnR) vs pars plana vitrectomy (PPV) and had met the management of primary rhegmatogenous retinal detachment outcomes randomised trial (PIVOT) criteria with a single break...

Acute retinal necrosis presumably caused by Epstein-Barr virus infection

Acute retinal necrosis (ARN) is an uncommon, but serious and potentially blinding condition. ARN is characterised by panuveitis, occlusive vasculopathy and progressive peripheral necrotising retinitis. The diagnosis is clinical but confirmation is sought via aqueous and vitreous sampling. Varicella zoster...

First systematic review of COVID-19 colonisation of ocular tissues and secretions

The authors present the first systematic review summarising all the data regarding SARS-CoV-2 colonisation of ocular and periocular tissues and secretions. They reviewed all publications between December 2019 to April 2020 in the Cochrane Library, Medline, World of Science and...

Success rates of primary and revision transcanalicular DCR surgery

Transcanalicular laser DCR is a relatively rare procedure compared to more conventional external or endo-nasal techniques. In this article the authors examine the outcomes of revision surgery following failed transcanalicular diode laser dacryocystorhinostomy (TCDL DCR), comparing a conventional external revision...

Vitreous loss fire drills – ophthalmic simulation improves trainee surgical competence and confidence with posterior capsule rupture scenarios

Ophthalmic trainees have reported limited exposure and low confidence regarding the management of cataract complications such as posterior capsule rupture (PCR) / vitreous loss (VL). This report evaluates the impact of a simulation-based educational training event on these concerns. Introduction...

Persistent subretinal fluid (PSFF) in pneumatic retinopexy (PNR) versus pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD): posthoc analysis of the PIVOT randomised trial

This is a posthoc study of the PIVOT randomised trial over a 12 month period, to evaluate the functional outcomes of the incidence of PSF in PnR versus PPV following RRD surgery. One hundred and fifty-eight patients were recruited and...

Tetracaine to reduce OCR

This study investigates the effects of Tetracaine eye drops on oculocardiac reflex (OCR) during strabismus surgery. A randomised controlled trial of 70 strabismus surgery patients aged two to 19 years was conducted with comparison of Tetracaine versus placebo. Demographics were...
