A 42-year-old man with Behcet's disease developed a rapidly growing mass under his right lower eyelid a week after transconjunctival cryotherapy. He underwent surgical drainage of the mass following imaging studies. Magnetic resonance imaging scans demonstrated the abscess, which did nor: violate the orbital septum. Cultures from drained material yielded Staphylococcus aureus. He recovered completely with systemic antibiotics. Preseptal abscess may occur as a complication of intense transconjunctival cryotherapy for intraocular disorders, and patients should be followed closely within the first few weeks postoperatively.
