Corneal newborn lymphatic vessels construct the afferent arc of corneal immunological reaction, which play important role in immune response. The corneal transplantation rejection rate rises due to the emergence of new lymphatic vessel which breaks the immunologic mechanism. With the founding of specific marker of lymphatic endothelial cells and research advancing of growth factor of lymphatic vessels, the mechanism, therapy and prevention of corneal immunological rejection reaction of corneal lymphatic vessel have been studied intensively. The graft survival rate has been greatly improved through inhibiting newborn lymphatic vessel.
