Mathieu Perreault was born with a rare condition
After the announcement that Perreault was going to miss 2-3 weeks with an eye injury, Eric Engels gave a bit more details on Perreault's situation:
«Mathieu Perreault started having some double vision and doctors realized his retina had detached. He found out he's got a condition called Lattice Retinal Degeneration. Had a small laser procedure to cure right eye and will be re-evaluated in a couple of weeks.»
«This is something Perreault was born with but never knew about until something went wrong. Wishing him a speedy recovery and hoping he never goes through it again.»
