Since the inaugural colloquium in 1961, the IPC has stood tall for over 60 years in bringing together experts from around the world who study pupillary responses in humans and animals to exchange their thoughts and ideas. The key highlight of the meeting is the Loewenfeld lecture held in commemoration of valuable services of Dr Irene Loewenfeld and her distinguished scientific position in the physiology of the pupil.
