Purpose:
To report a case of bilateral corneal graft dehiscence caused by blunt trauma.
Methods:
Case report of bilateral simultaneous corneal graft dehiscence with expulsion of the lens and iris as a result of airbag-induced trauma.
Results:
Both corneal buttons were resutured, the prolapsed iris tissue was repositioned in the right eye, and anterior vitrectomy was performed bilaterally. Topical and systemic antibiotics, topical steroids, cycloplegic agents, and antiglaucoma drugs were initiated. Repeated B-scan ultrasound examinations demonstrated an attached retina in both eyes. Three weeks after admission, the right eye was reoperated for removal of remnant lens material and additional anterior vitrectomy. The patient was fitted with polycarbonate spectacles with an optical correction of +8 in both eyes. Visual acuity improved to 20/200 and 0.5/60 in the right and left eyes, respectively. The right corneal graft regained transparency, but the left one remained hazy.
Conclusion:
Airbag deployment during motor vehicle collisions is a significant cause of ocular morbidity. The reported risk of airbag-related eye injury is 2.5% for any eye injury and 0.4% for severe eye injury. Patients undergoing corneal surgery should be counseled about the weakness of the donor-recipient interface and should consider wearing protective glasses.
