Editor,—The stroma comprises about 90% of the total corneal thickness1 and is responsible for most of the corneal tensile strength. Presumably because of its avascularity, healing of corneal stromal wounds is slower than in other connective tissues. Continued histopathological changes in human corneal laceration wounds have been observed years after injury, despite meticulous original suture closure.2 The wounds appear to undergo perpetual, dynamic remoulding, a fine balance between constructive and destructive processes. We report three cases of late, full thickness corneal wound dehiscence occurring spontaneously or after minor blunt trauma 17–56 years after the original injury. ### CASE REPORTS #### Case 1 A 61 year old man was referred for spontaneous corneal perforation right eye. At age 5, he had sustained a full thickness corneal laceration in this eye which was repaired with sutures. The patient did well with an uncorrected visual acuity of 20/50 right eye until the time of his corneal perforation 56 years later, whereupon he noted the sudden onset of eye pain and loss of …
