Penetrating orbital injury with organic foreign bodies.

OBJECTIVE

The authors reviewed the clinical features, diagnostic workup, and management of patients of penetrating orbital injuries with retained organic foreign bodies.

DESIGN

Retrospective, noncomparative case series.

PARTICIPANTS

Nineteen patients (15 males, 4 females) with penetrating orbital injuries due to organic foreign bodies.

RESULTS

The series included 15 (78.9%) males and 4 (21.1%) females who ranged in age from 6 months to 40 years (mean = 14.6 years); 12 (63.2%) patients were younger than 12 years of age. Twelve (63.2%) right and 7 (36.8%) left orbits were involved. Time between injury and presentation varied from a few hours to 9 months. Most common injury site was the superior orbit in 11 (57.9%) patients leading to abnormal extraocular motility (84.2%), proptosis (68.4%), and upper lid ptosis (47.4%). Associated pathologies also included acute cellulitis in 11, orbitocutaneous fistula in 5, and osteomyelitis in 2 patients. Preoperative computed tomography (CT) and magnetic resonance imaging (MRI) identified the foreign bodies in 42% and 57% of the patients, respectively.

CONCLUSION

Preoperative identification of the foreign material in the orbit was found to be very helpful for patient management but was only possible in approximately 50% of our cases with the use of CT and MRI. The vision in our patients usually improved shortly after treatment; the long-term complications more often included extraocular muscle and eyelid motility problems and periorbital scarring.
