Intravitreal dexamethasone implant for diabetic macular oedema

The authors report on the three-year outcomes of the Ozurdex Dexamethasone (DEX) intravitreal implant multi-centre trial for the treatment of diabetic macular oedema (DME). Patients with DME (best-corrected vision of 20/50 to 20/200 and central retinal thickness of ≥300µm) were...

Long-term meibomian gland function following a single thermal pulsation treatment

Dry eyes secondary to blepharitis and or meibomian gland dysfunction, though extremely common, is an annoyingly difficult condition to treat for several patients. Part of this difficulty lies in the inability of most patients to follow intensive and often times...

Augmented trabeculectomy with mitomycin C in primary congenital glaucoma

This study aimed to determine success of trabeculectomy augmented with mitomycin C (MMC) in children with primary congenital glaucoma (PCG) and document complications of this intervention. Over a two-year period, the authors treated 74 eyes of 42 children with PCG,...

Strabismus and binocular summation

The authors conducted a pilot study to investigate the effect of visual noise or background complexity on binocular summation in patients with strabismus. A target embedded in pixel noise was used. The study involved performance of a task detecting a...

In conversation with Fares Antaki: The retinal age gap in schizophrenia

Fares Antaki. Nima Ghadiri (NG): The ‘retinal age gap’ (RAG) is a relatively new concept. Based on your study [1], how confident are you in proposing this as a non-invasive, accessible biomarker for accelerated biological ageing in patients with neuropsychiatric...

Using ‘piggyback prisms’ to measure large angle strabismus – don’t simply add them together

An experimental study was conducted with the aim of developing a method to measure strabismus angles larger than 50 prism dioptres (PD) using ‘piggyback prisms’ – stacking Fresnel and block prisms. The stacked prisms were placed 2cm from the light...

Single vs combined y-split surgery for Duane’s type III

The authors present the results of two surgical approaches to treat exotropia Duane’s retraction syndrome (DRS) with significant overshoot and retraction. This study compared single Y-split recession of the lateral rectus muscle vs combined Y-split lateral rectus recession plus medial...

Reduced blood flow and age-related macular degeneration

This was a prospective cross-sectional study assessing changes in blood flow velocity in patients with age-related macular degeneration (AMD) using a retinal function imager. Sixty eyes with wet AMD were compared to 53 control eyes and the average blood flow...

RCT review of surgery for open angle glaucoma

This systematic review and meta-analysis examined eight randomised controlled trials (RCTs) to compare the intraocular pressure (IOP) reducing effect of three types of microstent implantation (Hydrus, iStent, CyPass) combined with phacoemulsification versus phacoemulsification alone for patients with open-angle glaucoma (OAG)...

Normative data using a virtual reality game-based visual field test

The authors present a prospective cross-sectional study involving healthy children to assess the use of a virtual reality game-based perimetry assessment. A single eye centre recruited through paediatric optometry and ophthalmology clinics over a 12-month period. Children aged <18 years...

Pathophysiology of diabetic macular oedema: why combination therapy may be better

The prevalence of diabetes has continued to increase over the years. It is currently estimated that there are 382 million with diabetes worldwide in 2013, and that this figure is expected to rise to 592 million by 2035 [1]. In...

Effect of alcohol dependency on visual function

The purpose of this study was to evaluate visual function, attention and psychological profiles in consumer and abstainer alcohol dependency syndrome (ADS) patients in a Portuguese population. The study was a quantitative, descriptive, cross-sectional and correlational study over a one-year...
