The eyes of suckermouth armoured catfish (Loricariidae, subfamily Hypostomus): pupil response, lenticular longitudinal spherical aberration and retinal topography [PDF]
, 2002 The dilated, round pupils of a species of suckermouth armoured catfish (Liposarcus pardalis) constrict slowly on illumination (over 35-40 min) to form crescent-shaped apertures. Ray tracing of He-Ne laser beams shows that the lenses of a related species (

The Effect of Pupil Size on Stimulation of the Melanopsin Containing Retinal Ganglion Cells, as Evaluated by Monochromatic Pupillometry [PDF]
, 2012 Purpose: To evaluate the influence of the size of the light exposed pupil in one eye on the pupillary light reflex of the other eye. Method: Using a monochromatic pupillometer, the left eye in each of 10 healthy subjects was exposed to 20 s of ...

Investigative Opthalmology & Visual Science, 2014 The postillumination pupil response (PIPR) is produced by intrinsically photosensitive retinal ganglion cells (ipRGCs). We aimed to refine the testing conditions for PIPR by investigating whether a greater PIPR can be induced using full-field light stimuli of shorter duration and lower intensity than that produced by existing protocols that use central-

Investigative Ophthalmology & Visual Science, 2015 We evaluated the test-retest reliability of current methods of inducing the melanopsin-driven postillumination pupil response (PIPR) under hemifield, central-field, and full-field stimulation conditions.Pupil response was recorded with an eye tracker in 10 visually normal participants.

Using the pupillary light response to measure cerebrovascular reactivity for dementia risk assessment [PDF]
With an ageing global population, the number of people living with Alzheimer’s disease, the leading cause of dementia, is increasing and is expected to continue to increase over the next few decades, with no known cure for the disease.

Melanopsin Sensitivity in the Human Visual System [PDF]
, 2016 The human retina contains long [L]-wavelength, medium [M]-wavelength, and short [S]-wavelength cones, rods, and intrinsically photosensitive retinal ganglion cells expressing the blue-sensitive (λmax = ~480 nm) photopigment melanopsin.

PupilMetrics: a support system for preprocessing of pupillometric data and extraction of outcome measures. [PDF]
The rapid pupillary constriction to an abrupt light stimulus is signaled through an oligosynaptic neural pathway that dominates over other supranuclear influences on pupillary movement.

Acta Ophthalmologica, 2012 AbstractQuantified pupil responses to colored light stimuli is a non‐invasive means to monitor melanopsin function as well as rod and cone activity. Understanding the trivariate contributions to the pupil light reflex has led to renewed interest in using the pupil response to monitor a variety of diseases.
