Risk factors for failed vision screening

Failure rates on vision screening tests were reported by age and racial / ethnic categories in a large sample of children with most aged 6-11 years. Many children resided in lower socioeconomic status areas. Data was taken from 9743 children....

Meibomian gland alteration in patients with primary chronic dacryocystitis: An in vivo confocal microscopy study

Chronic dacryocystitis affects tear film functionality and can predispose to ocular surface disease, however the specific effect of chronic dacryocystitis on meibomian gland function has not been studied. This group therefore performed in vivo confocal microscopy in 28 patients’ eyes...

Functional success of strabismus surgery

For this study the authors reviewed patients with bilaterally poor vision undergoing surgery for ocular realignment. Their vision was sufficiently low that patients could not assess their appearance. The purpose of the study was to document patient satisfaction with strabismus...

Under pressure: intraocular pressure and bariatric surgery

Obesity in the general patient population is increasing. The National Institute for Health and Care Excellence recommends bariatric surgery with body-mass index (BMI) of over 40, or between 35-40 and other significant disease that could be improved with weight loss....

Screening accuracy

In this study the authors observed whether and how well orthoptic tests are performed by non-orthoptists in a screening setting. They assessed the quality of screening tests by semi-structured observations of youth health care (YHC) physicians who screened children aged...

Effects of blood donation on the physiology of the eye

Hypovolaemia is a state of decreased blood volume, the reduction of which reduces tissue perfusion which may in turn lead to cellular hypoxia and end-organ damage. In blood donation, 500ml of blood is collected in ten minutes. This equates to...

Ocular neuromyotonia features

The authors present eight cases of ocular neuromyotonia (ONM) with an overview of the pathophysiology, aetiology, clinical presentations and possible treatments. Diagnosis was made only after thorough and repeated orthoptic examinations and review of medication history. An overview of the...

Fusional vergence measurement

This paper reports a systematic review to address two objectives: 1, to compare the normative values of tests measuring fusional vergence; 2, to investigate sources of heterogeneity of prism accuracy. The review was conducted according to PRISMA guidelines with a...

Ocular adnexal marginal zone b-cell lymphoma

This is a multicentre retrospective study of seven eye centres of 689 patients with ocular adnexal extranodal marginal zone b-cell lymphoma (OA-EMZL). The median follow-up time was 42 months and the median age was 62 years. Fifty-five percent were women;...

Online retinoblastoma surveillance tool

Given the vision and life-threatening course of retinoblastoma (RB), it has become a significant heritable childhood cancer to screen for. To recommend surveillance, risk must be estimated and genetic testing plays a vital role. However, genetic tests vary based on...

Nepafenac punctal plugs after cataract surgery: a new alternative?

The nepafenac punctal plug delivery system (N-PPDS) is an experimental L-shaped plug made of nonbiodegradable, preservative-free medical-grade silicone. It can deliver a sustained level of nepafenac for six weeks. This is a prospective, randomised, parallel-arm, double-masked, placebo-controlled, phase II pilot...

Profile of sports-related ocular trauma

The authors conducted a previous study on the epidemiology of sports-related ocular trauma in Quebec. In this study they aim to gather further information on presentation via ophthalmology and emergency departments. They undertook a follow-up study from a tertiary care...
