Giant iridodialysis with wound dehiscence following penetrating keratoplasty: an ocular emergency

Description

Wound dehiscence is a known complication of keratoplasty which can occur even many years following the surgery. Usually trivial trauma is the causative factor for wound dehiscence, but spontaneous dehiscence has also been reported in the literature.1

A 45-year-old man presented with sudden loss of vision in the left eye following a blunt trauma. History revealed penetrating keratoplasty in the left eye for perforated corneal ulcer 2 years ago. On examination, visual acuity was hand movement close to face in the left eye and right eye being within normal limits with 20/20 visual acuity. Slit-lamp biomicroscopic examination showed broken monofilament nylon sutures leading to superior 6 clock hours (09:00 to 03:00 clock hours) of wound dehiscence, with corresponding 6 clock hours of giant iridodialysis prolapsing anteriorly (figure 1). The lens was completely extruded along with vitreous at the wound. Based on the relevant history and clinical findings, a...
