Immune factors in corneal graft rejection.
This panorama of the immune factors in corneal graft rejection covers a spectrum of mechanisms which play a role in the opacification of corneal grafts. Great emphasis has been accorded to the role of transplantation immunity. The clinical and experimental evidence implicating transplantation immunity in the rejection of corneal grafts has been critically reviewed. In addition, evidence is pres...

Background: Rejection is the most common cause of late corneal graft failure. The purpose of this study is determining the prevalence, and defining the role of those factors which may affect the risk for rejection. Methods: The study was conducted on all patients who had penetrating keratoplasty without immunosuppressive therapy with at least 1 year follow up. Demographic status, cause of graft...

متن کاملRisk Factors for Failure of Keratoplasty in Keratoconus: Penetrating vs. Deep Anterior Lamellar Keratoplasty
Purpose: To determine the etiologic factors on rejection and failure rates and ocular surface changes after corneal transplantation by either DALK or PKP, in cases of keratoconus (KCN). Methods: In this cross-sectional study, considering the existing data, patients with keratoconus referring to Labbafinejad Medical Center from 2006 to 2016, who underwent corneal transplantation, were enrolled a...
متن کاملPrognostic factors for corneal graft recovery after severe corneal graft rejection following penetrating keratoplasty
BACKGROUND To investigate the outcome and prognostic factors for corneal graft recovery after severe corneal graft rejection following penetrating keratoplasty (PKP) treated with topical and systemic steroids. METHODS Fifty-eight eyes in 58 patients with severe corneal graft rejection following PKP were treated with topical and systemic steroids. Factors affecting the reversibility and mainte...
