Criteria were used in the Cornea Preservation Time Study (CPTS) to classify corneal rejection.
Patient selection: status post corneal transplant
Parameters:
(1) number of keratic precipitates
(2) increase in aqueous cells after usual early postoperative period
(3) endothelial rejection line
(4) inflammatory cells in stroma
(5) stromal and/or epithelial edema
