I'm with the other guys ... If your emergency room copay is more than a new bow then it's hard to justify the risk .... Obviously I'm being funny but seriously, God only gave you two eyes.
That might not be damage, might just be cracking in the finish. Hard to tell from pictures. If it were me, and I couldn't tell if the bow was damaged, I would strip the finish carefully and then examine to see if the cracking was in the finish only.
Good luck, and always aire on the side of caution.
