We studied six patients with early failure after Watson's trabeculectomy done due to chronic simple, neovascular, or chronic angle-closure glaucoma. After operation the eyes showed a maximum intraocular pressure (IOP) between 50 mmHg and 66 mmHg and no filtering bleb. Reoperation on the 5th to 14th post-operative day showed incarceration of ciliary body into the trabeculectomy fistula in all cases. The uveal protrusion was replaced and a deep corneoscleral block was removed in front of the scleral spur in three cases, and electrocoagulation of the anterior edges of the trabeculectomy fistula was done in other three cases. After a 4 months to 1.5 years follow-up IOP was 12 mmHg to 18 mmHg and only two eyes needed medical therapy. The results suggest that trabeculectomy in front of the scleral spur is indicated to avoid incarceration of the ciliary body into the trabeculectomy fistula.
我们研究了6例因慢性单纯性青光眼、新生血管性青光眼或慢性闭角型青光眼而接受Watson小梁切除术且早期手术失败的患者。术后，这些眼睛的眼压最高在50 mmHg至66 mmHg之间，且无滤过泡形成。术后第5天至第14天进行的再次手术显示，所有病例均有睫状体嵌入小梁切除瘘管。3例患者将葡萄膜突出物复位，并在巩膜突前方切除深层角膜巩膜组织块，另外3例患者对小梁切除瘘管的前缘进行了电凝治疗。经过4个月至1.5年的随访，眼压为12 mmHg至18 mmHg，仅2只眼需要药物治疗。结果表明，为避免睫状体嵌入小梁切除瘘管，应在巩膜突前方进行小梁切除术。
