Prognostic 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...
متن کاملTopical Bevacizumab Therapy in Graft Rejection After Penetrating Keratoplasty
Neovascularization is defined as formation of new vessels from vascular endothelial cells derived from existing blood vessels. These new immature vessels are friable. They have increased permeability, lack structural integrity, and can result in lipid deposition and corneal opacities. Ultrastructurally, corneal neovascularization is characterized by vessels encroaching through separated stromal...
متن کاملcorneal graft biomechanics after penetrating keratoplasty in keratoconus
purpose: to evaluate corneal hysteresis and corneal resistance factor in penetrating keratoplasty grafts in a group of keratoconic eyes using the ocular response analyzer (ora) and to evaluate the relationship between donor size, donor-recipient disparity and central graft thickness (cgt), and ora parameters. methods: this cross-sectional study was conducted on 34 eyes of 34 keratoconus patient...
متن کاملCorneal neovascularization as a risk factor for graft failure and rejection after keratoplasty: an evidence-based meta-analysis.
TOPIC Preoperative corneal neovascularization (CNV) is thought to be associated with an increased rate of corneal graft failure and potentially also graft rejection. CLINICAL RELEVANCE New therapeutic options that offer differential influence on the ingrowths or regression of either corneal blood or lymphatic vessels force us to re-evaluate the known data about the role of CNV in keratoplasty...
متن کاملImmune 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...
