Agreeing terminology for non-classic visual field abnormalities

The authors present a prospective survey of neuro-ophthalmologists. The survey comprised of 10 visual fields. The selection of visual fields for the survey aimed for variety and excluded classic neuro-ophthalmology visual field defects, e.g. hemianopia, nasal step. The survey was...

Visual field changes in thyroid eye disease (TED)

This study is a retrospective non- comparative review of visual field (VF) tests in patients with compressive optic neuropathy from thyroid eye disease (TED-CON). Ninety-six visual fields in 68 patients were included in the study and a two-step analysis of...

Selection of visual field test for detection of pituitary disease

This prospective cross-sectional diagnostic accuracy study compared Octopus semi-automated kinetic perimetry (SKP) and Humphrey static automated central perimetry for detection of neurological visual field loss in patients with pituitary disease. Humphrey central 30-2 SITA threshold programme results were compared with...

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...

Functional visual field loss using automated static perimetry

Functional visual field loss is traditionally assessed by kinetic perimetry, typically producing spiralling isopters. This study looked at the spatial distributions of functional field deficits using automated static perimetry. A retrospective review of automated perimetry records was conducted using a...

Transsynaptic retrograde degeneration linked to homonymous visual field loss after stroke

centre, of individuals identified with homonymous visual field loss post ischaemic stroke. Exclusion criteria were bilateral ischaemia, anterior / pregeniculate visual pathway affected and other pathology with the potential to effect visual fields. The following were extracted from the medical...

Comparison of visual field indices between normal adults and children

The authors present a prospective observational study which aimed to compare visual field indices with retinal nerve fibre layer (RNFL) thickness using optical coherence tomography (OCT) in normal adults and children. Children aged 6–18 years were recruited from a single...

Using a driving simulator to explore the effect of visual field loss from optic disc drusen

The purpose of this study was to compare driving simulator performance of participants with visual field loss (VFL) from optic disc drusen (ODD) with a normally sighted control group and a group of individuals with glaucoma. Data on performance and...

Is virtual reality perimetry as reliable as static perimetry in detecting neurological visual field loss?

This study compares agreement between virtual reality perimetry (VRP) and static automated perimetry (SAP) in a variety of neuro-ophthalmological conditions. For this work the Order of Magnitude (OM) VR-based visual field assessment system was used which has been developed by...

RCOphth asks ophthalmologists to ‘show leadership’

The Royal College of Ophthalmologists has issued advice and guidance for ophthalmologists regarding COVID-19.

Patients with low vision benefit from optical sector seeing ‘beyond the eyes’

Patients with low vision are benefitting from an initiative developed by Visualise Training and Consultancy and funded by Thomas Pocklington Trust. Seeing Beyond the Eyes has released its impact report which highlights a huge increase in the number of optical professionals who will now refer patients with low vision to vital support services – up from only 9% to an impressive 96%.

Biopsy of nasolacrimal duct using sheath guided dacryoendoscopy

In this study the author’s biopsied six eyes of five individuals with recurrent nasolacrimal duct obstruction following a prior dacryoendoscopic probing. All procedures were performed under local anaesthetic, the obstruction or lesion was directly visualised with dacryoendoscope and biopsy was...
