Repeatability of Online Circular Contrast Perimetry Compared to Standard Automated Perimetry.

Prcis: Online circular contrast perimetry provides visual field assessment on any computer or tablet with no extra hardware. It has good test repeatability and reliability that is comparable with standard automated perimetry. It holds promise for use in disease screening and surveillance to expand the provision of glaucoma care.

Online Circular Contrast Perimetry: A Comparison to Standard Automated Perimetry.

Purpose: The aim was to validate and compare the diagnostic accuracy of a novel 24-degree, 52-loci online circular contrast perimetry (OCCP) application to standard automated perimetry (SAP).

Design: Prospective cohort study.

Methods: Two hundred and twenty participants (125 normal controls, 95 open angle glaucoma patients) were included.

Circular Contrast Perimetry via Web Application: A Patient Appraisal and Comparison to Standard Automated Perimetry.

Purpose: The purpose of the study was to compare a novel, 24°, 52-locus online circular contrast perimetry (OCCP) application against standard automated perimetry (SAP) in terms of both diagnostic accuracy and patient attitudes.

Design: This was a cross-sectional study.

Subjects: Ninety-five participants (42 controls and 53 open-angle glaucoma patients) were included.

Online circular contrast perimetry via a web-application: optimising parameters and establishing a normative database.

Purpose: To establish a normative database and optimise parameters for personal-computer based perimetry via a web-application using circular contrast targets.

Methods: Online 24-degree 52-loci perimetry was delivered through a web-application using circular flickering contrast targets. Embedding contrast differentials within targets allows calculation of relative decibel (rdB) per 256-bit greyscale level differential.
