Orbital cellulitis and abscesses are typically secondary to a maxillary, ethmoid, or frontal sinus infection. Rarely, it may also be seen after orbital trauma. In cases of penetrating orbitofacial trauma caused by a foreign body, the presence of any foreign body in the intraorbital tissues should be investigated with radiological imaging, however, an initial examination may be insufficient. Suspicious examination findings require close follow-up and surgical exploration for non-visualized foreign bodies. Though orbital abscesses are often bacterial in origin, the causative agent varies depending on the etiology, and in cases of a possible infection, the culture should be studied and treated appropriately. Vision loss of some 10% can occur in an untreated orbital infection. Early recognition and timely treatment of an orbital infection is important in order to avoid potentially deadly conditions, such as cavernous sinus thrombosis, brain abscess, or meningitis. In this case report, a case of orbital abscess occurring after a tree branch-related orbital injury and the clinical approach applied for a 76-year-old patient are reviewed in the context of the relevant literature.
