As physical, occupational and speech therapists working with children with complex needs (and too often) exhausted families and disconnected teams that don't always see eye-to-eye, we recognised the need for clinical discussions that go beyond what we can gather from textbook and published guidelines.

An Eye-Opening Interview with Dr. Susan Barry on Neuroplasticity and Vision

A podcast header showing Dr Susan Barry, Professor Emeritus of Biological Science and Neuroscience about Developmental Optometery and Vision Recovery

Dr. Susan Barry


Stereo Sue

When it comes to understanding how the work that we try to do every day in the clinic actually works, this interview with Dr. Susan Barry may be one of the most eye-opening interviews I have done so far - excuse the pun.

Dr. Barry is a a Professor Emeritus of Biological Sciences, Professor Emeritus of Neuroscience and Behavior and (as she calls herself) a recovered Strabismic.

Her story of fixing her gaze which started at age 48 gives us unmatched insight how neuroplasticity can be harnessed in every day therapy to drive recovery.

We cover topics from the value of clinical wisdom and the cautionary tales of over interpreting published research to the importance of not being distracted by the obvious problems you see, but rather understanding the reason behind why you are seeing them to drive effective rehabilitation.

There’s so many nuggets to take away from this interview, you are going to love it - enjoy!
