visuALL Field Analyzer (vFA) Compared to Standard Humphrey Automated Perimetry

Glaucoma, Open-Angle Clinical Trial

Official title:
How Does the visuALL Field Analyzer (vFA) Compare to Standard Automatic Perimetry (SAP) in Patients With Mild and Moderate Chronic Open Angle Glaucoma (COAG) and Subjects Without Eye Problems?

Clinical Trial Summary

To determine age-adjusted reference values of the visuALL Field Analyzer (vFA) retinal sensitivity and to assess the repeatability of the measured values and compare them with those measured by a Standard Automatic Perimetry (SAP).

Clinical Trial Description

Standard Automatic Perimetry (SAP) is the gold standard test for the evaluation of central and peripheral retinal sensitivity to light for detection and monitoring optic nerve diseases such as glaucoma. The current device has its own limitation such as positioning for the duration of the test which makes is hard for older patients especially those with back or other musculoskeletal diseases, artifact of the corrective lenses used to accommodate the patients refractive errors, etc. Several devices have been developed since the advent of the Octopus Perimeter 3-5 and the Humphrey Field Analyzer (HFA), in an effort to improve the test reliability and patient comfort. The main goal of this study is to evaluate the repeatability of a novel psychophysical platform that takes advantage of a Head Mounted Device (HMD) with eye tracking capabilities. Other objectives of this study include the development of an initial reference database and comparison of the measured parameters with HFA. ;
