目前治疗无晶体性青光眼的手术方法通常仅对瞳孔阻滞所致的闭角型青光眼和恶性青光眼有效,对原发或继发性开角型青光眼疗效甚差。其失败的主要原因是结膜纤维化增生,玻璃体疝入滤过部位,虹膜嵌顿在滤道及睫状体剥离的裂隙闭合。为了既能消除抵抗房水外流的主要部位,又不进入无晶体眼前房,作者设计了一种非穿通性小梁切除术(简称NPT)。 Current surgical methods for the treatment of aphakic glaucoma are usually only effective for angle-closure glaucoma and malignant glaucoma due to pupillary block, with poor efficacy in primary or secondary open-angle glaucoma. The main reason for its failure is fibrosis conjunctival hyperplasia, vitreous hernia into the filtration site, iris incarcerated in the filter and ciliary body stripping the fracture closure. In order to both eliminate the main part that resists the outflow of aqueous humor and not enter the anterior chamber without aphakia, the authors designed a non-penetrating trabecular surgery (NPT).
