Abstract:
We describe six patients with 12 separate episodes of self-inflicted periocular foreign body injuries, which presented to our institution recently. All patients were male, relatively young (mean 28.5 years old), incarcerated, and had significant underlying psychiatric conditions. The subjects had inserted staples (6), paperclips (2), or other small metallic wire segments (4) into the periocular region. Most cases (9/12) involved concurrent self-inflicted injury to other body parts. Ten cases involved foreign bodies inserted through the palpebral conjunctiva into the upper eyelid, while two cases involved insertion into the orbit. Identification and surgical retrieval of foreign bodies was successful in most cases (9/11) but was not attempted in one case. Self-inflicted periocular injuries, while rare, are challenging cases for which the ophthalmologist should be prepared. A multidisciplinary approach, including psychiatric assessment and treatment, is important for optimal care.
