Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. Oso definitely should be fully checked by your local vet. Difference in pupils size can be caused by ocular trauma (for example blunt trauma to the eye when Oso hit the bench) or less frequently, by brain concussion / brain trauma. Your vet will be able to distinguish between these two problems and recommend treatment, if required.
