CRYSTALSIGHT Cohort 2.0

Sponsor: Tan Tock Seng Hospital

View on ClinicalTrials.gov

Summary

Age-Macular Degeneration (AMD) is a common eye condition and a leading cause of vision loss among people age 50 and older. It causes damage to the macula, a small area near the centre of the retina needed for sharp, central vision. It is estimated that the prevalence of early and late AMD in Asian populations aged 40 to 79 were 6.8% and 0.56% respectively. Prevalence in white populations estimated from large population studies were 8.8% and 0.59% respectively. With the aging population and people living longer, these numbers will only increase. Hence, this study aims to develop a system to evaluate OCCUTRACK's CRYSTALSIGHT device through remote monitoring for disease recurrence of wet aged-related macular degeneration using eye gaze tracking.

Amsler Grid

The Amsler grid is a tool used to monitor the macula, the central part of the retina, for changes in vision that can be indicative of various eye conditions, particularly age-related macular degeneration (AMD). It helps detect and monitor metamorphopsia (distorted vision) or scotoma (blind spots) in the central visual field.

DEVICE

CRYSTALSIGHT

OCCUTRACK's CRYSTALSIGHT device tracks these eye movements with generated patterns on the screen, a visual assessment of affected and unaffected eyes is achieved without expensive optics and at home on any tablet or laptop computer. CRYSTALSIGHT is a home-based gaze-tracking readily available for home hyperacuity monitoring for these and other high-risk eyes with diagnosed wet-AMD.
