Mapping areas to target location of vision screening services

In this study, the authors analysed data from a community vision screening program to determine the efficiency of vision screening in reaching lower income populations. The study used ArcGIS (Esri) mapping software to develop a visual representation of areas needing...

Could Twitter boost the impact of ophthalmic journal articles?

*Equally contributing co-first authors. The authors investigate the link between ‘tweets’ and citations for 155 articles from five key ophthalmology journals. Social media’s impact on our lives has been significant, allowing easy discussion of topics worldwide. An increasing number of...

IgG4-related disease or Graves orbitopathy

This is retrospective review of patients who had been diagnosed with both IgG4-related ophthalmic disease (IgG4-ROD) and Graves orbitopathy over a four year period. Eight patients were identified. The diagnosis of IgG4-ROD was based on 10 or more IgG4+ plasma...

Is pre-eclampsia / eclampsia a risk factor for non-infective uveitis?

Testing of binocular contrast sensitivity as an objective measure of severity in intermittent exotropia

The purpose of this study was to compare the binocular contrast sensitivity ratio (measured with the Vision CSV-100 vector chart) between 40 intermittent exotropia patients and 40 normal controls. The authors also evaluated the effect of intermittent exotropia compensation status...

Predictors of IOP reduction after SLT

The aim of this study was to identify predictors of intraocular pressure reduction following selective laser trabeculoplasty (SLT) in patients with primary open-angle glaucoma, who are already taking maximally tolerated IOP-lowering medication and need further IOP reduction. In this prospective...
