The evaluation of corneal graft tissue by the use of trypan blue.

Background: The quality of the donor cornea, which basically depends on the condition of the endothelial sheet, is an important factor for the successful outcome of penetrating keratoplasty.

Patients And Methods: In this retrospective study, we present our experience in using trypan blue staining for the examination and evaluation of 498 consecutive corneal grafts from 251 donors, concerning their suitability for penetrating keratoplasty, during the decade 1986-1995.

Possible role of transferrin in exfoliation syndrome.

Protein concentration was measured in 30 exfoliation syndrome samples and 22 age matched controls. Exfoliation samples contained significantly more protein than controls. We also analyzed by SDS gel electrophoresis 32 aqueous samples, 12 with exfoliation syndrome and 20 age matched controls.
