EYE - Neuro-ophthalmology
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, optic nerve, perimetry, visual fields
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
3 April 2023
| Lauren R Hepworth
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...

EYE - Neuro-ophthalmology
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...
iCare COMPASS Automated Fundus Perimetry
COMPASS is the first Fundus Automated Perimeter capable of performing standard 24-2 visual field testing and delivering TrueColour confocal images at the same time. The device provides confocal images of the retina, as well as measurements of retinal threshold sensitivity,...A novel test for unilateral functional visual loss

Bilateral concurrent eye examination, functional visual loss, head-mounted perimetry
The authors report results of three cases of functional visual loss, where regular ophthalmic testing was not sufficient to confirm the diagnosis. In these cases, bilateral concurrent eye examination was performed using a head-mounted perimeter (imo), to facilitate the diagnosis....
