RESUMO
Valsalva-associated orbital compartment syndrome in the setting of orbital cellulitis, mucocele, or subperiosteal abscess has not been previously reported. A previously healthy girl presented with orbital cellulitis complicated by a subperiosteal abscess and frontoethmoidal mucocele. On the day of her planned orbitotomy and endoscopic sinus surgery, she developed a Valsalva-associated retrobulbar hemorrhage and elevated intraocular pressure after crying during a blood glucose fingerstick. An urgent canthotomy and cantholysis in addition to the planned endoscopic sinus procedure was performed. She did well post-operatively with normal vision at follow-up. Based on these experiences, there should be a consideration to implement heightened vigilance to prevent or minimize Valsalva maneuvers in orbital cellulitis patients with subperiosteal abscesses or mucoceles extending into the orbit. While it remains unclear whether and to what degree these patients may be at an increased risk of developing retrobulbar hemorrhage leading to orbital compartment syndrome, we hope that this novel report aids in providing another consideration with the goal of preventing vision loss.
