"When I deal with a patient who's had a concussion, you're not just dealing with the concussion, you're dealing with the concussion plus all of the pre-existing history"

We speak with Dr. Patrick Quaid (Optometrist, FCOVD, PhD) about his background in optometry and his focused interest in vision rehabilitation for patients with learning difficulties and concussions. Dr. Quaid discusses common symptoms/complaints that may indicate an underlying vision issue in these populations, as well as treatment strategies used in vision therapy.
