Normal reference values for the RETeval device

The purpose of this study was to provide normative data of full-field electroretinography (ERG) responses in the paediatric population using the RETeval device in healthy children with normal retinas. This was a prospective study of 38 eyes of 20 patients...

A log in the eye

"My friend wanted to show how far he could throw that log. So, he helicoptered it over his head, faster and faster and when he let go, it hit my eye at full speed,” a young lady of 19 years...

What’s next in retinal imaging? Faster, deeper and full-on

Fast-evolving technological leaps are opening the way toward clinically useful ocular coherence angiography, generating 3-dimensional microvasculature maps without intravenous dye injection, as well as whole-eye imaging, handheld patient-operated optical coherence tomography (OCT) devices and, for challenging vitreoretinal procedures, integrated intraoperative...

OCTA FAZ measurements in vein occlusion

Previous studies have confirmed that foveal avascular zone (FAZ) enlargement is correlated with visual acuity impairment in patients with retinal vein occlusion (RVO). This current study aimed to evaluate the OCT angiography parameters: the area of FAZ, foveal and parafoveal...

Brn3b neuroprotective effect in rat glaucoma model

An adeno-associated virus-directed overexpression of the Brn3b protein in hypothesised to confer neuroprotective effects in this paper. This is ultimately tested in a well-accepted rat glaucoma model (Morrison’s model: saline injection into episcleral veins of rat eyes with a force...

Retinal findings in COVID-19 patients

This is a single centre cross-sectional study from Brazil between 20 to 23 May 2020, with a total of 18 patients; nine male and median age was 62.5-years-old. 10/18 (55.6%) had retina abnormalities upon dilated eye examination. Flame-shaped haemorrhages were...

Treatment outcomes for retinal detachment

This is a retrospective, nationwide, multicentre study with retinal detachment (RD) in the Japan-RD registry between 2016 to 2017. The primary outcome was the estimated mean difference of postoperative corrected visual acuity (CVA) in six months and a propensity score...

Silicone oil (SOT) versus gas (GT) tamponade for primary rhegmatogenous retinal detachment treated successfully with a propensity score analysis

This is a retrospective, nationwide, multicentre study with retinal detachment (RD) in the Japan-RD Registry between 2016 to 2017. The primary outcome was the estimated mean difference of postoperative cerebral vascular accident (CVA) in six months and a propensity score...

Is thrombolytic treatment warranted for central retinal artery occlusion?

Central retinal artery occlusion (CRAO) is a subtype of acute ischaemic stroke which results in severe visual loss. Acute CRAO is equivalent to a brain acute ischaemic stroke (AIS), as the obstruction of the central retinal artery (CRA) causes end-organ...

Silicone oil in rhegmatogenous retinal detachment

Silicone oil (SO), used in complicated retinal detachments, is associated with complications such as cataract, increased intraocular pressure (IOP), keratopathy, cystoid macular oedema (CMO), epiretinal membrane (ERM) and loss of vision. Emulsification of oil can also lead to migration of...

Visual outcomes after surgery for primary rhegmatogenous retinal detachment in era of microincision vitrectomy

This is a prospective, multicentre, nationwide study between 2016 and 2017, to investigate the preoperative ocular factors, surgical techniques (pars plana vitrectomy (PPV) or scleral buckling (SB), or combined procedures) for rhegmatogenous retinal detachment (RRD) and postoperative best corrected visual...

Sickle cell maculopathy

This paper reports the result of a prospective study to analyse the prevalence of sickle cell maculopathy (SCM) and its associations with age, sex, genotype, proliferative sickle cell retinopathy (PSR) stage, and the impact on visual acuity (VA). This study...
