Epiblepharon management

This single centre review was conducted over 15 years to determine the frequency, indications and long-term follow-up of those referred for surgery as well as those treated conservatively for epiblepharon. Eighty-nine patients aged two months to 14 years (mean age...

Comparison of visual fields between migraine and tension type headaches

The aim of the study was to compare the clinical features and visual fields of patients with migraine without aura and tension type headache. Visual fields were assessed whilst the patients were having an attack of pain and tested using...

E-Dobson card for visual acuity

The authors assessed the utility of an electronic Dobson acuity card which can be altered for spatial frequency. Thirty-six infants and toddlers aged 5-36.7 months were recruited – equal females and males. Fourteen had high refractive error. The card is...

Use of RAPDx device with optic nerve disease

The authors have previously reported on use of the RAPDx device for evaluating relative afferent pupillary defects (RAPD). RAPDx objectively determines the magnitude of RAPD by presenting light stimuli alternately to pairs of eyes with laterality. The parameters of amplitude...

Automated Bruckner device accuracy

The authors developed a Bruckner device, examined volunteers and determined the relation between the luminance of the red fundus reflex and eye rotation. Eye rotation was varied continuously both horizontally (-7 to 8 degrees) and vertically (five degree total range)...

Binocular summation with low contrast

The magnitude of binocular summation was investigated in normal control subjects using four different letter charts of varying type with fixed and variable contrast levels and spatial frequency to determine which tests most readily reveal binocular summation in normal subjects....

Optic disc haemorrhages as a risk factor for poor outcomes in IIH

This is a report of a review of optic disc photographs, of the type and frequency of the optic disc haemorrhages (ODH), papilloedema grades and other fundoscopic abnormalities at baseline. In the study eyes of 133 patients enrolled in the...

William’s syndrome

William’s syndrome is a congenital multisystem disorder involving the cardiovascular, connective tissue and central nervous systems. The aim of this study was to evaluate the frequency and severity of ophthalmic manifestations and associated diseases as well as provide epidemiology data...

Optical quality difference between monofocal and multifocal intraocular lenses

It is well known that multifocal intraocular lenses (IOLs) can generate more than one focus to restore distance and near vision, but patients may experience adverse optical phenomena such as decreased contrast sensitivity and induced glare or halos. The authors...

Prostaglandin associated periorbitopathy

Prostaglandins are known to cause periorbital adverse effects. The aim of this retrospective case series was to compare the frequency of prostaglandin associated periorbitopathy (PAP) between bimatoprost, latanoprost and travoprost users. Five PAP findings were evaluated: upper lid ptosis, deepening...

Stroke-vision symptoms

The purpose of this study was to investigate the frequency and type of visual symptoms following stroke and evaluate what certain factors were associated with the absence of visual symptoms. This was a prospective, multi-centre, observation cohort study with 915...

Risk calculation variability over time in OHT

In this study the authors aimed to assess the variability of the well documented risk model from the Ocular Hypertension Treatment Study (OHTS) that identified higher intraocular pressure (IOP), older age, lower central corneal thickness (CCT), greater vertical cup-to-disc ratio...
