Biography

Dr. Wittich’s research domains include basic sensory science, as well as medical, psychosocial, and rehabilitation approaches to sensory loss. Coming from a background in age-related vision loss, he now conducts research in dual sensory impairment and deaf-blindness. Specifically, he examines the use and usability of assistive technologies intended to improve quality of life and social participation of older adults with sensory impairment.

Originally from Germany, Dr. Wittich pursued a Bachelor’s and Master’s degree in Psychology (Concordia U) and a PhD in Visual Neuroscience (McGill). He then completed a postdoctoral fellowship in audiology at the Centre de recherche of the Institut universitaire de gériatrie de Montréal. He became a Fellow of the American Academy of Optometry in 2011 and in 2012 was certified by the Academy for Certification of Vision Rehabilitation & Education Professionals as Quebec’s first Certified Low Vision Therapist (CLVT).

Dr. Walter Wittich, UNIVERSITY OF MONTREAL’S SCHOOL OF OPTOMETRY, MONTREAL, QUEBEC We’ve spent a lot of time researching head mounted devices; they’re getting smaller, lighter and cheaper. There’s no longer a stigma attached, and the advantage for the visually impaired is they’re hands-free. For example, they are perfect for playing the piano. A single camera is mounted onto the glasses which in real-time projects a modified picture to two screens on the inside where the lenses would be. This picture can be pre-programmed to change color or enhance an image. Each device requires an OD to carry out a refraction. Prices start at $500 and there’s really no top limit since cost is connected to what the device can do. A competitive field and moving fast.

Interview with Dr. Walter Wittich

DeafBlind Ontario Services  

2018-01-01

“My research aims to improve functional ability, social participation, and quality of life for persons with vision and/or hearing loss. In addition, I am interested in how these combined impairments influence the use of assistive devices, the stigma related to assistive technologies, and the interactions among the device user, the rehabilitation provider, and the device itself,” said Dr. Wittich.

The association between tactile, motor and cognitive capacities and braille reading performance: a scoping review of primary evidence to advance research on braille and aging

As the prevalence of age-related visual impairment increases, a greater understanding of the physiological and cognitive capacities that are recruited during braille reading and the potential implications of age-related declines is required.

The efficacy of a technology-driven visual arts recreation activity, delivered virtually, was evaluated for its potential to achieve positive impacts, similar to traditional arts-interventions, on wellbeing in long-term care residents. Thirty-one residents (average age 86.8 years; SD = 9.4) engaged with the arts-intervention for 30-minutes, twice weekly, for 6 weeks with either a partner or as part of a group. Wellbeing indicators included self-reported psychological and health-related wellness, and attention capacity. Binomial tests of postintervention change revealed a significant above-chance probability of improvement in one or more wellbeing indicators (p < .05). Postparticipation feedback survey scores were positive (p < .05). Cognitive status did not influence outcome; however, other participant characteristics such as younger age, higher openness-to-experience (personality trait), and lower baseline mood were significantly associated with positive response to the intervention (p < .05). Findings demonstrate technology may be an effective platform for promoting accessibility to beneficial arts-interventions for older adults.

Continuum of Care for Older Adults With Concurrent Hearing and Vision Impairment: A Systematic Review Protocol

PROSPERO Preprint

Atul Jaiswal, Shikha Gupta, Patrice Dupont, Walter Wittich

2020-08-25

A recent global report estimates around 2% of the world population (~ 150 million people) to have concurrent hearing and vision di culties (referred to as dual sensory impairment/DSI). Older adults with DSI often experience poorer levels of health and barriers to accessing health services in long-term care, home care and hospitals. Yet, the evidence is limited to inform the healthcare planning for this vulnerable population. Understanding the current state of the continuum of care for older adults with DSI is paramount to determine ways to promote healthy ageing. Hence, the objective of this systematic review is to summarize the information available on the continuum of care and synthesize evidence on existing and emergent strategies of screening, assessment and interventions to optimize care for older adults with DSI.

Meaning and experiences of participation: a phenomenological study with persons with deafblindness in India

2020-08-19

Deafblindness, also known as dual sensory loss, creates a distinct condition more disabling than either deafness or blindness alone. The participation experiences of persons with deafblindness have not been understood well. This phenomenological study aims to understand the meanings of participation for persons with deafblindness and identify the domains of life that are important to them.
