Background: Patients following penetrating keratoplasty (PK) remained at risk for wound dehiscence at the graft-host junction even years after surgery. The aim of our study was firstly to assess the quadrant specificity between traumatic and spontaneous wound dehiscence at the graft-host junction and secondly to determine the incidence of traumatic and spontaneous wound dehiscence.
Methods: The medical records of all 170 patients who underwent a penetrating keratoplasty from March 1,1996 to April 30, 2006 were retrospectively reviewed. During a 10-year period 10 eyes showed signs of open wound dehiscence after blunt ocular trauma or spontaneously after the removal of penetrating keratoplasty suture.
Results: Over the 10-year period, the incidence of traumatic wound dehiscence was performed was 2.35% (4 from 170 patients) and the incidence of spontaneous wound dehiscence after suture removal 3.53% (6 from 170 patients). In traumatic wound dehiscence separation occurred in 76.2% at the nasal part, in spontaneous wound dehiscence in 71.3% at the temporal part. Except in 1 eye, all of the resutured grafts retained clarity.
Conclusions: Quadrant specificity for dehiscence was observed with the involvement of the nasal part in traumatic wound dehiscence as a result of indirect, contre-coup type of forces, and of the temporal part in spontaneous wound dehiscence probably due to direct forces.
