Transient visual loss caused by crowded optic discs

The author presents four cases of transient visual loss (TVL) in young females (age range at presentation 14-22 years) with crowded optic discs. Patient demographics, investigations, medical and social histories are provided for all patients. A review of evidence for...

Assessment of slow and fast vergence in stroke survivors

The authors present the findings of a prospective cohort study. Three hundred and five stroke survivors were recruited consecutively. The following exclusion criteria were applied; aphasia, cognitive impairment, visual inattention, ocular motor nerve palsy and neuromuscular disease. Fifty age-matched controls...

Screening for visual processing deficits in dementia

The Queen Square Screening test for Visual Deficits (QS test) screens for changes in visual processing. It has never been formally validated as a single test. The test consists of a short booklet developed using remnant object and spatial perception...

Using optical coherence tomography angiography to detect MoyaMoya vasculopathy

Moyamoya (MM) disease is a chronic cerebrovascular disease that can lead to progressive stenosis of the terminal portions of the internal carotid arteries and their proximal branches. The authors carried out a cross-sectional cohort study to investigate vascular changes in...

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...

G-CSF intravitreal injections for NAION: a pilot study

In rodent models with anterior ischemic optic neuropathy (AION), granulocyte colony-stimulating factor (G-CSF) confers a neuroprotective effect on retinal ganglion cells (RGCs) via anti-apoptotic and anti-inflammatory processes. This prospective study investigated the efficacy of intravitreal injection of G-CSF for the...

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%...

Management and outcomes of congenital fibrovascular pupillary membranes (CFPM)

Congenital fibrovascular pupillary membranes (CFPM) is defined as a white fibrous membrane across the pupil which may be an ectopic iris tissue arising from the aberrant migration of neural crest cells or a variant of persistent fetal vasculature. The authors...

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...

Needling procedure for failed bleb

The aim of this study was to determine the efficacy of needling with 5-FU after failed filtering procedures in the paediatric population. This was a retrospective review of 324 filtration surgeries in 265 children with 55 eyes (16.9%) undergoing needling...

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...
