蚕蚀性角膜溃疡是一种原因不明,慢性疼痛性溃疡,从周边部开始首先向周围然后向中央持续地进展,最后侵犯全角膜,对其病因曾有许多推测,但都没有得到证实。最近有的作者研究证明蚕蚀性角膜溃疡邻近结膜的组织培养的代谢产物可降解胶原和角膜的蛋白醣原,同时结膜组织学的检查见有大量的浆细胞和淋巴组织浸润,由此说明结膜和蚕蚀性角膜溃疡的发病机理密切有关。 Mooren ulcer is an unexplained, chronic pain ulcer, starting from the periphery of the first to the periphery and then to the central continuous progress, and finally violations of the whole cornea, there have been many reasons for its speculation, but have not been confirmed. Some recent studies have shown that the metabolites of tissue culture adjacent to the conjunctival of corneal ulcer can degrade the protein glycogen of collagen and cornea. At the same time, examination of conjunctival histology showed a large number of infiltration of plasma cells and lymphoid tissue, And Mooren ulcer pathogenesis is closely related.
