Correlation analysis of reject reaction and corneal endothelial cells after penetrating keratoplasty from donation after cardiac death

AIM: To study the relativity between reject reaction from donation after cardiac death(DCD)and corneal endothelial cell source of corneal graft after penetrating keratoplasty.METHODS:Totally 28 cases of corneal graft rejection after penetrating keratoplasty with cardiac death donor cornea were analyzed using corneal endothelial microscope at less than 1mo, 2-3mo, 4-6mo, 7-12mo after operation.RESULTS:Coefficient variation of corneal endothelial cell of the 28 cases at less than 1mo,2-3mo, 4-6mo and 7-12mo were 38.23%, 49.56%, 57.18%, 65.04%. Corneal endothelial cell density were 2071.15±311.47, 1771.33±348.18, 1626.59±353.92, 1553.14±307.31. The coefficient variation of corneal endothelial cells was positively correlated with rejection(r=0.95, P
