    Abstract:
    BACKGROUND AND PURPOSE: Blunt ocular trauma to a corneal transplanted eye represents a higher risk for wound rupture at the donor-recipient interface. We have evaluated the causes, clinical characteristics, treatment and outcome, particularly the graft's clarity, in patients with traumatic wound dehiscence after penetrating keratoplasty. METHODS: Between March 1996 and April 2006, over a period of 10 years, 4 patients who had previously undergone successful penetrating keratoplasty and subsequently sustained traumatic wound dehiscence were treated at our department. All eyes underwent primary wound closure with interrupted 10-0 nylon sutures. RESULTS: Over the 10-year period, the incidence of traumatic wound dehiscence in which penetrating keratoplasty was performed was 2.35 % (4 of 170 patients). The ages of our patients at the time of injury were 6, 76, 78 and 39 years. The interval between penetrating keratoplasty and trauma varied from 12 through 16 and 17 to 30 months. All corneal dehiscences occurred at the graft-host junction. All dehiscences were at the temporal-superior quadrant (4 of 4 eyes) and at superior-nasal and temporal quadrants in 3 of 4 eyes. Two eyes that were pseudophakic had lost their implants and required anterior vitrectomy. In one of these patients (a 76-year-old women) delayed-onset expulsive choroidal haemorrhage occurred at the end of surgical repair. Visual outcome was correlated with the force of trauma, previous eye conditions and complications during surgery. All of the resutured grafts retained clarity. CONCLUSION: Traumatic wound dehiscence is a serious and not uncommon complication following penetrating keratoplasty. Despite severe trauma, graft transparency was achieved in all cases and there was no need for regrafting.
