Cornea itself has no blood vessels, capillary network around the limbus, if blood vessels beyond the limbus into the
transparent area is pathological. Corneal neovascularization, corneal disease is not an independent, but a pathological changes. Avascular
cornea as to maintain balance factor is destroyed, the limbus peripheral capillaries invade the cornea 1-2mm, may be regarded as corneal
neovascularization (CNV) is formed. With the elimination of its infection, wound healing, immune-mediated inhibition of corneal melting
have a role, but its structure and function is imperfect, prone to plasma leakage, resulting in corneal edema, corneal lipid calm and inspire
scarring, seriously affect vision; also corneal transplant rejection rates increased significantly. Conducive to the growth of CNV removal
of pathogenic microorganisms and tissue repair, but seriously affect the transparency of the cornea, resulting in a series of complications
and damage to the integrity of the eye, at home and abroad for the treatment of corneal neovascularization lot of drugs study and hope
through different medications, different treatment methods to solve this major problem. |
