[Resistance of limbo-keratoplasty to blunt trauma]. / Stabilität der Limbo-Keratoplastik bei stumpfem Bulbustrauma.

BACKGROUND: Traumatic wound dehiscence is a rare complication after penetrating keratoplasty. Limbo-keratoplasty seems to alter the pattern of rupture after blunt trauma. CASE REPORT: We report on one patient with dehiscence of a penetrating limbo-keratoplasty after blunt trauma. RESULTS: The dehiscence occurred over the entire extent of the clear corneal scar, whereas the sclero-corneal interface remained adapted. CONCLUSIONS: This case suggests a different tensile strength of these two scar types, possibly associated with their different grades of vascularization or epithelialization.
