Orbital compartment syndrome due to periorbital angioedema.

A 68-year-old female presented with an episode of unilateral orbital compartment syndrome due to periorbital angioedema. The patient made a consultation at the general Emergency Room with sudden left periorbital edema and serious diminished ipsilateral visual acuity, with examination detecting orbital compartment syndrome secondary to a probable allergic angioedema after ingestion of ibuprofen. She received treatment with intravenous and oral corticosteroids, achieving a rapid improvement in the condition and clinical follow-up was carried out, with evaluation of the peripapillary retinal nerve fiber layer thickness and computed perimetry. Periorbital angioedema due to ibuprofen can be a cause of orbital compartment syndrome whose diagnosis and treatment must be carried out urgently to prevent permanent visual impairment.
