Rod Sensitivity in Age-related Macular Degeneration (AMD) and Retinitis Pigmentosa (RP)

Retina Foundation of the Southwest·observational·Posted Oct 26, 2017·Updated Dec 23, 2019

In Brief

An observational study evaluating Rod sensitivity for Retinitis Pigmentosa and AMD. Completed, enrolled 40 participants across 1 site.

Detailed Summary

A new fundus-guided microperimeter (MP-3S) has been developed by Nidek, Inc. to track the fundus of the patient and present stimuli in specific anatomically-defined locations. Furthermore, this tracking means that exactly the same locations can be tested on subsequent (follow-up) visits. The investigators will use a method called two-color perimetry to map rod and cone sensitivity on this device. With this technique, the sensitivity difference (blue-red) to chromatic test stimuli can be used to determine whether rods, cones or both photoreceptor systems mediate the threshold at a given location in the macula.
