Professional life

In 1968, Steinbach was hired at York University by
Ian P. Howard Ian Porteus Howard (July 20, 1927 – June 1, 2013) was a Canadian psychologist and researcher in visual perception at York University in Toronto. Life and career Ian Howard was born in Lancashire, England, close to the Yorkshire border. He st ...
as his first postdoctoral fellow, as a Research Associate and as a Special Lecturer. In 1970 he became an Assistant Professor and was promoted to Associate Professor in 1973. From 1981 until 2002, Steinbach served as a Professor of

. In 1988, Steinbach along with Jean Real Brunette formed the Vision Health Research Council of Canada whose mission is to unify Canadian vision research and to advocate for vision research funding. He had an important impact on eye research and vision health in Canada. Steinbach's many awards and distinctions include: the Carl Kupfer Award, from the Association for Research in Vision and Ophthalmology, "For promoting vision research in Canada", the Chair's Award, Department of Ophthalmology and Vision Sciences, University of Toronto, Fellow of the Association for Research in Vision and Ophthalmology, and the Department of Ophthalmology and Vision Sciences' Faculty Research Day Lecture named, in perpetuity, in his honour. Steinbach wrote a bi-monthly invited column in the Canadian Journal of Ophthalmology called Cyclops: Update on progress in vision science, from 2005 to 2017.


Research

Steinbach areas of research interests included
eye movements Eye movement includes the voluntary or involuntary movement of the eyes. Eye movements are used by a number of organisms (e.g. primates, rodents, flies, birds, fish, cats, crabs, octopus) to fixate, inspect and track visual objects of i ...
, eye muscle
proprioception Proprioception ( ) is the sense of self-movement, force, and body position. Proprioception is mediated by proprioceptors, a type of sensory receptor, located within muscles, tendons, and joints. Most animals possess multiple subtypes of propri ...
, spatial and
motion perception Motion perception is the process of inferring the speed and direction of elements in a scene based on visual, vestibular and proprioceptive inputs. Although this process appears straightforward to most observers, it has proven to be a difficul ...
,
stereoscopic vision Binocular vision is seeing with two eyes, which increases the size of the visual field. If the visual fields of the two eyes overlap, binocular depth can be seen. This allows objects to be recognized more quickly, camouflage to be detected, spa ...
, central vision loss, and
visual illusions In visual perception, an optical illusion (also called a visual illusion) is an illusion caused by the visual system and characterized by a visual percept that arguably appears to differ from reality. Illusions come in a wide variety; their ca ...
. His research in eye movements included owls, which is significant because, contrary to the general belief that the owl's eyes do not move, Steinbach found that they do. In humans, his studies of eye movement control included normal and pathological populations. While studying the ocular motor function of patients treated for
strabismus Strabismus is an eye disorder in which the eyes do not properly align with each other when looking at an object. The eye that is pointed at an object can alternate. The condition may be present occasionally or constantly. If present during a ...
, Steinbach found that pre and post-surgical measures of visual direction provided insights as to the sources of information of the position of the eyes in orbit used by the brain. This information eventually led to the discovery of the Palisade Endings in humans. In comparing the effects of the total visual deprivation from enucleation with the partial deprivation from
amblyopia Amblyopia, also called lazy eye, is a disorder of sight in which the brain fails to fully process input from one eye and over time favors the other eye. It results in decreased vision in an eye that typically appears normal in other aspects. Amb ...
and normal
monocular vision Monocular vision is vision using only one eye. It is seen in two distinct categories: either a species moves its eyes independently, or a species typically uses two eyes for vision, but is unable to use one due to circumstances such as injury. Mon ...
, his research found enhanced perception of contrast-defined stimuli and mild impairments in motion perception as a function of monocular eye enucleation. He also examined visual direction and egocentre location in enucleated and strabismic children and adults and studied the cyclops effect. In studying the central vision loss produced by diseases such as
age-related macular degeneration Macular degeneration, also known as age-related macular degeneration (AMD or ARMD), is a medical condition which may result in blurred or no vision in the center of the visual field. Early on there are often no symptoms. Some people experien ...
his research had been directed toward the design of effective techniques to measure residual
