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...

Screening for stroke-related visual problems

The aim was to report the initial development and evaluation of a suitable screening tool for detecting visual problems after stroke. The tool has four components. The first three include questions asked by examiners about patients’ ocular history and symptoms,...

Vision screening opinion

The aim of this paper is to describe experts’ perceptions of best practice guidelines and competency frameworks for visual screening in children. A focus group of approximately 75 minutes duration consisted of five orthoptists and two paediatric ophthalmologists with more...

An unusual case of sellar chondroma

A single case of chondrogenic neoplasm arising from the base of the skull is presented and discussed. These benign and slow growing tumours in the sellar region are extremely rare and as such this article provides a useful insight and...

Use of the RAPDx device to evaluate efficacy of treatment in patients with optic nerve disease

The RAPDx objectively determines the RAPD magnitude by alternately presenting light stimuli to each eye and deriving amplitude and latency scores. The authors of this paper evaluated the amplitude and latency scores from the RAPDx together with other ophthalmic investigations...

Reduction of severe visual loss and complications following IAC for RB

This was a retrospective cohort study of patients with retinoblastoma (RB) who required intra-arterial chemotherapy (IAC) between 2013 and 2015, who had relapsed following systemic chemotherapy. A total of nine patients were included in the study and their ocular complications...

Translucent vs. lightproof occluders

This study investigates the change in visual acuity following occlusion in amblyopes and non-amblyopes using translucent versus lightproof occlusion of the dominant eye. Group 1 non-amblyopes consisted of 26 subjects: 16 visually normal and 10 strabismic or anisometropic subjects without...

Visual field progression after glaucoma drainage device implantation

This retrospective interventional case series assessed changes to visual fields after implantation of a glaucoma drainage device (Baerveldt, Ahmed or Molteno Devices) between 2010 and 2015. A total of 106 eyes from 96 patients were included in the final analysis...

Impact of amblyopia on adult planning and problem solving

This study sought to evaluate whether monocular amblyopia has an impact on planning and problem solving in the adult population. The authors used the Tower of London (TOL) test to address this question. The TOL test was developed to assess...

Microperimetry measurements in anisometropic amblyopia

The authors aimed to evaluate retinal sensitivity and fixation characteristics in children with anisometropic amblyopia by macular analyser integrity assessment (MAIA) microperimetry and to compare the results between amblyopia and fellow eyes. The study included 39 children; 21 female –...

A survey of neuro-ophthalmologists on use of corticosteroids in giant cell arteritis

While corticosteroids are the mainstay of treatment in giant cell arteritis (GCA), the type, dose, route and duration of treatment remains controversial. The authors surveyed 180 neuro-ophthalmologists on their use of this treatment via email in a two-month period. Results...

Differences between ages and onset in functional network changes associated with reading Braille

Visual impairment affects learning ability, speed and accuracy required for reading, writing and learning memory in terms of educational performance. Braille training requires decoding of simple dots into meaningful words and sentences. The objectives of this study were to evaluate...
