[Acute orbital trauma - risk of permanent impaired vision and double vision]

The purpose of this article is to highlight the importance of appropriate management of acute orbital trauma, in order to prevent permanent impaired vision and double vision. Orbital blowout fractures with entrapment, so-called trapdoor fractures, occur more often in children than in adults, and require immediate surgical intervention. A blowout fracture with impingement, so-called open door fracture, does not require immediate intervention. However, if the motility does not improve within 1-2 weeks surgery may be required. The symptomatology in children with orbital fractures may differ significantly from that in adults, and vasovagal symptoms such as bradycardia and nausea are common.  Orbital compartment syndrome is characterized by an acute increase in orbital pressure, and may result in irreversible blindness if not promptly treated with lateral canthotomy and cantholysis.
