Abstract:
Medmont Dark-Adapted Chromatic (DAC) Perimeter enables efficient and quantifiable evaluation of rod-mediated (scotopic) vision. DAC tests rod function at multiple retinal locations, creating a topographical map of rod-mediated vision. These dynamic rod responses can be used as a functional marker to monitor disease progression and functional alterations in inherited retinal dystrophies, such as retinitis pigmentosa, Stargardt disease, cone-rod dystrophy, and choroideremia. In this chapter, we describe a protocol for the operation and analysis of the Medmont DAC in monitoring and assessing various retinal disorders.
