Twenty-six eyes which appeared rejection after allograft penetrating keratoplasty between April 2003 and April 2004 in Shandong Shi'erming Eye Hospital were collected, including 16 males and 10 females, 9 cases were repeated relapsing viral keratitis, 8 cases were traumatic posterior corneal leucoma, 5 cases were corneal decompensation caused by various intraocular surgery, 2 cases were congenital leucoma, and 2 cases had other symptom. The rejection occurred at 2 month to 2.5 years after operation. Among them 19 cases were transferred to our hospital and asked adding traditional Chinese therapy because western medicine was ineffective in other hospital.
