Automated Vision Assessment and Impairment Detection Through Gaze Analysis in Wet AMD Patients
Sponsor: Tan Tock Seng Hospital
Summary
The study aims to evaluate the Automated Vision Assessment and Impairment Detection through Gaze Analysis (AVIGA) system in the ability to detect and assess central vision dysfunction in a personalized, adaptive, objective, and automated way through eye gaze tracking in age-related macular degeneration (AMD). We also aim to develop a novel algorithm / scoring methodology for disease activity monitoring over time (delta-change). AVIGA visual risk prediction cut-off scores will be presented together with probabilities of occurrence of prespecified adverse clinical outcome.

Automated Vision Assessment and Impairment Detection through Gaze Analysis (AVIGA) system
AVIGA is an automated method and system for vision assessment of a subject. The method includes the following: determining a set of test patterns for the subject based on a preliminary assessment of an eye of the subject; displaying the set of test patterns sequentially to the subject; collecting data on the subject's gaze in response to each test pattern displayed; and correlating central vision function of the subjects to the collected gaze data. Subjects perform the AVIGA test monocularly and pursue a pre-determined target moving in a customized waveform across the computer screen. The trail of the gaze points generated by the subject following the target is simultaneously recorded and stored. 1. Static Fixation Evaluation (SFE) 2. Static Perimetry Assessment (SPA) 3. Static Perimetry Sensitivity Assessment (SPSA) 4. Pursuit
