  • Title: Hairpulling causing vision loss: a case report.
    Author: Puri S, Duff SM, Mueller B, Prendes M, Clark J.
    Journal: Orbit; 2019 Apr; 38(2):162-165. PubMed ID: 29727255.
    Abstract:
    Subperiosteal extension of a subgaleal hematoma (SGH) to the orbit is a reported, but rare complication of trauma. This report details a 13-year-old African-American male who originally presented to the emergency department after trauma with headache and was found on CT imaging to have a contained subgaleal hemorrhage. He presented 2 days later with increased pain and proptosis of the left eye with findings of decreased visual acuity, elevated intraocular pressure, proptosis, and complete external ophthalmoplegia. Repeat imaging revealed enlargement of the SGH with subperiosteal extension into the left orbit. He required an emergent lateral canthotomy with inferior and superior cantholysis, followed by surgical drainage of the subperiosteal and SGH. Hematologic workup for coagulopathy was negative. The authors urge point-of-care providers to consider ophthalmic evaluation for patients with large SGHs where orbital extension and vision loss may occur. Furthermore, SGH causing orbital compartment syndrome may develop in patients who have normal blood work and clotting factors.
