Orbital Apex Syndrome and Central Retinal Vein Occlusion after Blow-out Fracture Repair

ABSTRACT

Purpose@#To report a case of orbital apex syndrome and central retinal vein occlusion after blow-out fracture repair.Case summary: A 22-year-old man who underwent emergency re-operation in a department of plastic surgery due to pain, decreased visual acuity, and ophthalmoplegia in all direction after orbital blow-out fracture repair was referred to ophthalmologist on postoperative day 2 and there was no improvement in symptoms. He showed severe complications, including optic neuropathy and ophthalmoplegia in all direction, central retinal vein occlusion, and outer retinal disruption caused by orbital apex hemorrhage. Although we were concerned that it was too late, we started high dose steroid intravenous pulse treatment and the visual acuity, ophthalmoplegia, and retinal findings were improved. However, the optic atrophy and visual field defect did not. @*Conclusions@#After a complicated blow-out fracture repair in other department, if a patient shows severely decreased visual acuity or ocular movement limitation, a thorough and immediate ophthalmologic examination is recommended. During ophthalmologic examination, meticulous examination of the entire eye, including the retina, is required, in addition to general orbital complications. A relatively good prognosis can be expected through accurate cause analysis and appropriate treatment for the confirmed abnormal findings.
