- Diagnosis of orbital compartment syndrome can be remembered by the mnemonic: DIP (Decreased visual acuity, Increased IOP, Proptosis)
- Indications for lateral canthotomy: Vision loss, proptosis, EOM palsy, Elevated IOP (>40mmHg)
- Lateral canthotomy and cantholysis:
-- clamp with hemostat for 2 minutes;
-- using crush mark from hemostat;
-- perform lateral canthotomy with scissors perpendicularly
-- dissect inferiorly and snip the inferior crus of the lateral canthal tendon
-- recheck IOP after procedure
- Low risk of complication if only inferior cantholysis performed
