青光眼是眼科常见致盲眼病之一。抗青光眼滤过性手术经过多次改良,目前仍是治疗青光眼的主要方法,其目的是通过手术在球结膜下形成长期有功能的外滤过泡。但有些患者因种种原因滤过泡功能障碍,导致眼压升高,视功能再次受到损害。造成失败的主要原因就是滤过口处成纤维细胞增殖,瘢痕组织形成,患者难以建立有效的滤过通道而最终导致滤过 Glaucoma is one of the common ophthalmic diseases that cause blindness. Anti-glaucoma filtration surgery after repeated improvements, is still the main method of treatment of glaucoma, its purpose is to form long-term under the bulbar conjunctiva outside the filtering bleb. However, some patients due to various reasons filtering bleb dysfunction, resulting in increased intraocular pressure, visual function again undermining. The main reason for the failure is the proliferation of fibroblasts at the mouth of the filter, the formation of scar tissue, and the difficulty in establishing effective filtration channels in patients leading to filtration
