Topical Bevacizumab Therapy in Graft Rejection After Penetrating Keratoplasty
نویسندگان
چکیده
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 lamellae. Corneal vascularization following penetrating keratoplasty may result in graft rejection.

CASE REPORT A 75-year-old man with bilateral idiopathic lipid keratopathy underwent a penetrating keratoplasty in the left eye. One month later, there was deep corneal neovascularisation extending across the bed and the graft-host interface, with a whitish opacity surrounding the vessels. Topical bevacizumab (25mg/mL) was administered 4 times daily for 2 months with partial regression of cornea...
متن کاملPenetrating keratoplasty for keratoconus: complications and long-term success.
A series of 100 penetrating keratoplasties for keratoconus performed between 1968 abd 1986 were reviewed for long-term results. The mean follow-up was 6.1 years with a range of 4-16 years. The systemic associations and the postoperative complications were analysed. Grafting in cases associated with Down's syndrome had a higher incidence of complications. 93% of grafts remained clear and 81% ach...
