We propose AVIGA, a system for Automated Vision assessment and impairment detection for Age-related Macular Degeneration (AMD) through Gaze Analysis. The assessment of visual symptoms is important for the detection, monitoring and screening of AMD, which is an increasingly prevalent eye disease and leading cause of blindness in the aging population. Current methods of vision assessment require forced fixation, rely on oral report or manual response, and necessitate the presence of a doctor. The AVIGA system assesses vision through gaze analysis. Its advantage has two folds. For the patients, it does not require forced fixation or oral/manual response thus the progress is more relaxing and the result is more objective. For the clinicians, it is easy to operate and does not need the presence of an ophthalmologist. A trained nurse is capable of operating the test. We collected seven persons’ data and validated the system
