Headset perimetry

Visual field analysers are traditionally large table mounted devices, designed specifically for field capture and analysis. Over the last year or so a number of companies have started to disrupt this space with the introduction of headset-based field analysers, mostly...

Reliability of kinetic perimetry in children and young adults

This study reports on normative visual field area, feasibility and repeatability of testing for a large sample size of healthy children and young adults, using Octopus semi-automated kinetic perimetry. Sample included 221 healthy volunteers aged 5-22 years. The study was...

Predicting ischemic lesion location using perimetry

The authors present a retrospective records review, using the search terms homonymous hemianopia, visual field loss and MRI. Only posterior circulation artery territory ischemic strokes were included. Demographics, stroke details and initial and follow-up with 24-2 SITA Standard perimetry results...

Avoiding prominent facial features during perimetry

The authors present a case series including six healthy participants prospectively recruited. All participants had no ocular pathology. The assessment included identification of their dominant eye for use in testing. A 60-4 SITA standard visual field assessment was completed in...

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...

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...

Using perimetry to support lesion location in the retrochiasmal visual pathway

The authors present a retrospective case review of patients with homonymous hemianopia from a 30-year period. Inclusion criteria included completion of perimetry within two years of diagnosis and a MRI brain. Data extracted from the records included demographics, diagnosis details...

Using frequency doubling technology perimetry to identify Alzheimer’s disease early

Alzheimer’s disease is widely reported to be associated with deficits in visual function. Visual disturbances include impaired stereopsis, contrast sensitivity and motion detection. Deficits specific to the magnocellular pathway (MGC) have been identified in Alzheimer’s disease. This article compares the...
