Objective: To evaluate the chromatic pupillary response as a means of assessing outer and inner retinal function in patients with retinitis pigmentosa (RP).
Design: Evaluation of diagnostic technology.
Participants: Thirty-two patients with RP and visual loss and 43 normal subjects.
Objective: To weight the rod-, cone-, and melanopsin-mediated activation of the retinal ganglion cells, which drive the pupil light reflex by varying the light stimulus wavelength, intensity, and duration.
Design: Experimental study.
Participants: Forty-three subjects with normal eyes and 3 patients with neuroretinal visual loss.
