The conference programme will include both themed sessions and free sessions. We welcome research presentations on any studies of pupil response mechanisms. We particularly encourage contributions to any of the topics below.

Autonomic Nervous System: Sympathetic and parasympathetic pathways and mechanisms for control of pupil responses, and effects of central and peripheral lesions.

The Afferent Visual Pathway: Components of the Pupil Light Reflex as objective biomarkers of the integrity of the afferent visual apparatus (in health and disease).

Cognitive Neuroscience: The use of pupil responses as a tool to investigate attention, arousal, perceptual load and cognitive processes.

Pupil pharmacology: Changes to the pupil induced by drugs acting either centrally or peripherally. 

Non-image forming visual pathways: Including the neurobiology of ipRGCs, their synaptic connections within the retina and their central projections and functions. The role of ipRGCs in the control of the pupil response, light flux sensing and blindsight.

Optics and vision: Effective retinal illuminance (apodization), higher order aberrations, discomfort glare, vision in capsulotomy, etc.

Pupil responses as a measure of sleepiness and fatigue: Industrial applications. 

Comparative studies: Pupil responses in non-human species. Evolutionary advantages, diversity of function and response properties, optical advantages, comparison to human studies.
