Diplopia and enophthalmos after surgical repair of blowout fracture.

Author information

Department of Ophthalmology, University of Pittsburgh, PA, USA.



To evaluate the incidence of residual diplopia and enophthalmos and the possible risk factors leading to their occurrence in patients who had orbital blowout fracture repair.


Forty-two patients with pure orbital blowout fracture who had at least 6 months postoperative follow-up were included in the study group. Nineteen (45.2%) patients had orbital floor, two (4.8%) patients had medial orbital wall and 21 (50%) patients had a combination of orbital floor and medial orbital wall fractures. The fracture was reconstructed with porous polyethylene (Medpore) in 22, supramide in 12 and gelatin (Gelfilm) in 8 orbits. Mean postoperative follow-up was 11 months.


Preoperatively, 35 patients (83%) had diplopia and 13 patients (30.9%) had enophthalmos greater than 2 mm. Of 35 patients who had preoperative diplopia, only 7 (17%) patients experienced diplopia postoperatively. Diplopia improved 1 to 4 weeks (mean, 3 weeks) following surgery in 28 patients. Timing of surgery and age of the patient were significant for the development of postoperative diplopia (p < 0.05). Sex, location of the blowout fracture and the alloplast material were not found to be significant for the development of postoperative diplopia (p > 0.05). Enophthalmos persisted in three (7%) patients postoperatively.


Old patients were more likely to have residual postoperative diplopia. Surgical repair of blowout fractures within two weeks of trauma decreases the incidence of residual diplopia.
