AMBLYOMETER "The Rivalrous Bridge"
“Ambly” denotes dimness and the Amblyometer
is an instrument for (1) detecting perceptual difference
in brightness between the two eyes and for (2) quantifying
this difference by measuring the change in brightness
necessary to bring the two sides of the visual system into
balance.
Measures Relative Afferent Defects in Seconds
BENEFITS
Quickly Screen Children and Adults for Relative Afferent Defects
Detects Amblyopic Defect in Children as young as 3 year old
Direct Comparison of ENDPOINT, Compare Test Brightness to Control Brightness
Simple: "Which is Brighter 1 or 2?"
Monitor
the Effect of Amblyopia or Optic Nerve Therapy
Detects more diseases than RAPD
Easy Test: Instant Learning Curve
DiagnosticGame™: A Game with a Purpose
The "Rivalrous Bridge"
Analogy to Wheatstone Bridge
