[Endothelium of the donor's transplant after penetrating keratoplasty].

The results of a follow-up of changes in the transplant endothelial cells in 208 patients (209 eyes) in the periods from 1 week to 5 years after surgery helped the authors define the criteria for the choice of donor material with consideration of the endothelial status for various groups of patients. They suggest a method for differential diagnosis of tissue incompatibility reactions and infection recurrences in patients who were operated on for herpes virus keratoiridocyclitis by means of reflecting biomicroscopy of the endothelium. The minimal count of cells necessary for the transplant to remain transparent was estimated.
