Major Aylesworth became functionally blind by December 1917. His case was reviewed by a medical board on December 1, 1917 and at that time it was reported that he could not read, could not shave himself and can only lace his boots by feel. The diagnosis was Tobacco Amblyopia. The Board recommended that he be returned to Canada. Upon his return to Canada, a neurologist recommended that he be sent to the Homewood Sanitarium in Guelph, Ontario, but Aylsworth refused, and he was permitted to take responsibility for his own care.
Attempted to transfer from 95th Battalion to 123rd Battalion at Niagara Camp, but had to be dropped from the roster when the number of officers exceeded establishment.
