Where along the vergence pathway is affected by Parkinson’s Disease?

The authors outlined three hypothesis for the effect Parkinson’s Disease has on blur- and disparity-driven vergence with reference to location within the vergence system that is affected to be tested in this prospective study. The study recruited 14 participants with...

Outcomes after surgery for INS

The purpose of this study was to detail clinical and electrophysical outcomes after extraocular muscle surgery in adults with infantile nystagmus syndrome (INS). This was a single centre prospective case series of 81 patients aged 18-72 years (mean 36); 63%...

Objective vs. subjective torsion measures

This study aimed to explore the relationship between subjective and objective torsion in normal individuals with no manifest strabismus. The study included 118 eyes of 59 normal people aged >15 years using Heidelberg OCT and the Torsionometer. There were 27...

IOL power calculation accuracy in childhood cataract surgery

Refractive outcomes in eyes after vitrectomy vary as the timing of cataract surgery may influence the outcome when done as staged surgery after vitreoretinal (VR) surgery or at the same time as VR surgery. The authors aimed to determine the...

Visual acuity conversion to digital acuity

The author proposes a basic set of evidence-based digital acuities for alpha vision to facilitate formatting of visual acuity data uniformly. This work was informed by a review of the literature. A full table provides US and international classification of...

Spot screen versus cycloplegic refraction

This study compared the spherical, cylindrical and spherical equivalent values obtained by the Spot screener before and after induction of cycloplegia with the values of cycloplegic refraction to explore the application value of the Spot screener in refractive error screening...

RCT of VR training versus occlusion for amblyopia

The purpose of this study was to compare the visual outcomes of occlusion with game playing through a virtual reality (VR) system in children with unilateral amblyopia. The study was undertaken at the Negah Eye Hospital in Iran. This was...

Pilot trial of virtual reality to treat amblyopia beyond the age of seven years

A pilot double-blind randomised controlled trial is presented. Patients were required to be between seven and 38 years of age, have a diagnosis of anisometropic and / or strabismus unilateral amblyopia, visual acuity in the amblyopic eye between 0.3-1.0 LogMAR...

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...

Cystoid macular oedema following retinal detachment surgery

There are limited studies examining the incidence and risk factors for postoperative cystoid macular oedema (CMO) following rhegmatogenous retinal detachment (RRD) repair. Postoperative CMO is thought to be due to pro-inflammatory state, where numerous cytokines lead to tight junction dysfunction,...

Foveal displacement after macular hole surgery

Previous studies show that internal limiting membrane (ILM) peeling during macular hole surgery is associated with retinal shrinkage (microtubule depolymerization of the axons of the inner retina) and nasal shift of the fovea. A temporal inverted ILM flap technique was...

Are any precautions needed when performing cataract surgery in thrombocytopenic patients?

In this retrospective multi-centre study, charts for 196 eyes of 150 thrombocytopenic patients were reviewed. The mean preoperative platelet level was 73.0 ± 20.5 × 103/μL (median of 76.0 × 103/μL), with a range of 17 to 100 × 103/μL...
