Traumatic Wound Dehiscence after Penetrating Keratoplasty

ABSTRACT

Case of traumatic wound dehiscence after penetrating keratoplsty were evaluated. Six eyes of six patients which had sustained traumatic wound dehiscence after penetrating keratoplasty done between 1994 and 1997 were included in the study. Among the six patients, four were men,two were women and age ranged from 13 to 62 years (average, 36 years). Penetrating keratoplasty was performed due to visual loss from keratoconus (n=3), herpes keratitis (n=2), leukoma cornea (n=1). The mean duration between penetrating keratoplasty and traumatic wound dehiscence was 10.83 months. Direct hit in the eyes by fist, elbow, bumping against iron post and door handle were the cause leading to wound dehiscence. Corneal donor-recipient junction is known to be vulnerable to trauma and all the wound dehiscence in the six eyes developed at donor-recipient junction, especially at inferior portion. Vision recovered after primary closure of the wound but was worse than before the traum due to the development of corneal opacity and astigmatism.
