Visual PerceptionLaajuus (10 ECTS)

Objective

Students are able to describe basic functional principles of nerve cells and the neural circuitry and connections of these to the structures of the central nervous system. They are able to describe the anatomy of the parts which are involved in visual perception and eye movements. They are able to describe the significance of the light and its properties to the visual function. They are able to describe the main features of neurophysiological activity of the visual system, visual information processing and visual perception, and how the changes of the nervous system affect vision. Students are be able to measure the stereoscopic vision, colour vision, contrast sensitivity and visual field and recognize significant deviations from the physiological values. They understand the role of vision screening as a part of an optometrist’s work and are able to plan, implement and produce a report on vision screening.

Content

Components of the nervous system; structure and functions of a nerve cell; the brain, the spinal cord and the peripheral nervous system. Thinking, cognition and understanding. Interpretation and use of information, generation of visual information, general functional principles of perceptive systems. Visual agnosias, hemineglect, nervous diseases (multiple sclerosis, dementia, Parkinson's disease).
Psychophysical measurements, light and its significance to visual stimulation, receptive fields, processing visual information, eye movements and their neural coordination. Colour vision; tests and assessment of defects and problems related to them. Spatial and temporal properties of vision, contrast sensitivity, stereoscopic vision and qualitative perimetry and assessment methods. Vision screening; planning, implementing and reporting.
