visuALL Field Analyzer (vFA) Compared to Standard Automatic Perimetry


Brief description of study

To determine age-adjusted reference values of the visuALL Field Analyzer (vFA), to assess the repeatability for each parameter and correlate them with a Standard Automatic Perimetry (SAP) parameters.

Detailed Study Description

Standard Automatic Perimetry (SAP) is the gold standard test for the evaluation of different diseases of the visual pathway like glaucoma. Its main goal is to measure the differential light sensitivity at several locations of the central and peripheral field of vision. Nevertheless, the accuracy of the current device is limited by several factors like the inherent inconsistency of the psychophysical test, stressful examinations and frequency of testing among others.

Several devices have been developed since the advent of the Octopus Perimeter3-5 and the Humphrey Field Analyzer (HFA), in an effort to improve early detection of glaucoma.

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 the evaluation of its correlation with HFA parameters.
