目的 临床评估作者设计的穿透性小梁切除和滤道成形术的安全性和有效性。方法 在穿透性小梁切除术中,于巩膜办下植入一个T形“人工小梁支架”,借助巩膜静脉丛制成一个永存的可吸收房水的间隙。本文选用PMMA制成的人工晶状体的T形袢作支架,为8例志愿者9只绝对期或近绝对期青光眼做了这一手术。观察期5～22个月,平均15.7个月。结果 平均眼压从术前的45.6mmHg降至24.22mmHg。9眼中8眼保持了功能性或部分功能性滤遇泡;2眼视力从持续20多天无光感分别恢复到有光感和0.05。结论 本文提出的穿透性小梁切除和用PMMA制成的T形人工晶体袢作为“人工小梁支架”进行的滤道成形术安全有效,无论对开角和闭角型青光眼,降眼压效果均显著而持久,适应症比传统的非穿透性小梁切除术更广泛,应用前景光明。
Objective To evaluate the safety and efficacy of the authors in the design of penetrating trabeculotomy and filter angioplasty. Methods In penetrating trabeculectomy, a T-shaped “artificial trabecular stent” was implanted under the sclera and scleral venous plexus to create a perpeturable gap between absorbable aqueous humor. This article selected T-shaped intraocular lens made of PMMA as a stent, 8 volunteers, 9 patients with absolute or near-absolute glaucoma done this surgery. Observation period of 5 to 22 months, an average of 15.7 months. Results The average intraocular pressure decreased from 45.6mmHg before surgery to 24.22mmHg. Eight of nine eyes maintained functional or partial functional filtration; the visual acuity of two eyes returned to a sense of light and 0.05, respectively, from the dullness of more than 20 days. CONCLUSIONS The penetrating trabeculotomy and T-shaped intraocular lens made of PMMA, which are proposed in this paper, are safe and effective as filter angioplasty for “artificial trabecular stents”. Both open-angle and angle-closure glaucoma, The results are significant and lasting, indications than the traditional non-penetrating trabeculotomy more widely, the application of bright prospects.
