Evidence has accumulated that rod activation under mesopic and scotopic light levels alters
visual perception and performance. Here we review the most recent developments in the …

Recently discovered intrinsically photosensitive melanopsin retinal ganglion cells contribute
to the maintenance of pupil diameter, recovery and post‐illumination components of the …

The number of research groups studying the pupil is increasing, as is the number of
publications. Consequently, new standards in pupillography are needed to formalize the …

Methods.: Forty-one patients (25 with glaucoma and 16 healthy age-matched control
participants) were tested. Intrinsically photosensitive retinal ganglion cell function was directly …

Intrinsically photosensitive retinal ganglion cells (ipRGC) signal environmental light level to
the central circadian clock and contribute to the pupil light reflex. It is unknown if ipRGC …

Purpose.: The post-illumination pupil response (PIPR) has been quantified using four metrics,
but the spectral sensitivity of only one is known; here we determine the other three. To …

purpose. A cathode-ray-tube (CRT) monitor–based technique was used to isolate clinically
significant components of dark adaptation. The utility of the technique in identifying …

Purpose: This study investigates the clinical utility of the melanopsin‐expressing intrinsically
photosensitive retinal ganglion cell (ipRGC) controlled post‐illumination pupil response (…

Melanopsin-containing intrinsically photosensitive retinal ganglion cells (ipRGCs) are a
class of photoreceptors with established roles in non–image-forming processes. Their …

Purpose.: We determined the relative contributions of rods, cones, and melanopsin to pupil
responses in humans using temporal sinusoidal stimulation for light levels spanning the low …
