TitelOrbital subperiosteal hemorrhage caused by mask squeeze during scuba diving
Abstract Nr.135
DoelOrbital hemorrhage due to recreational scuba diving is a very unusual finding. We report two cases of subperiosteal hemorrhage caused by mask squeeze.
MethodesTwo case reports.

ResultatenTwo male scuba divers experienced a sudden onset of periorbital pain during the descend of a dive, followed by proptosis of the left eye after the dive. Imaging revealed a subperiosteal hemorrhage under the orbital roof in both cases. The first patient had a large proptosis and hypoglobus. He had no light perception due to optic nerve compression and required an urgent surgical drainage of the subperiosteal blood. The second patient had mild proptosis with periorbital petechial hemorrhages. His vision was normal and a conservation attitude was taken. Both cases recovered completely.
Discussion: Physiopathology of ocular barotraumas will be explained, and needs to be differentiated from other vascular or neurological insults related to diving.
ConclusieOrbital hemorrhage is a potentially vision-threatening condition. Vision loss after scuba diving is not necessarily caused by decompression sickness. Periorbital pain should raise the suspicion for a typical subperiosteal hemorrhage. Urgent imaging and surgical intervention can restore vision
