PurposeTo describe the clinical course of patients with traumatic orbital compartment syndrome who underwent bony orbital decompression due to persistently abnormal pupillary light reflex after lateral canthotomy and cantholysis.MethodsFour consecutive patients were retrospectively reviewed. The authors performed bony orbital decompression as there was no improvement in the pupillary light reflex and a tight orbit persisted even after lateral canthotomy and cantholysis.ResultsThe median interval between injury and bony decompression was 8.8 hours (range, 7-12 hours). All patients showed a preoperative intraocular pressure of 40 mm Hg or greater, which decreased to 20 mm Hg or less the next day. Two patients showed globe tenting with a posterior globe angle of 110° or less, which was resolved on the following day. Two patients with initial visual acuity of counting fingers or better showed complete visual recovery. By contrast, only 1 of the 2 patients with no light perception slightly improved to light perception while the other showed no improvement after surgery.ConclusionsBony orbital decompression is effective for the treatment of traumatic orbital compartment syndrome in patients whose preoperative visual acuity is counting fingers or better.
