Three patients (a 15-year-old girl, a 45-year-old woman, and a 61-year-old woman) with previously successful full-thickness filtering procedures developed pigmented tissue in the fistula sites and uncontrolled intraocular pressures despite maximum tolerable medical therapy. The filtering procedures in the first and second patients spontaneously failed two and four years after surgery. The filtration bleb of the third patient, after successfully controlling intraocular pressure for six years, failed two months after cataract extraction. Argon laser therapy was applied through the conjunctiva to treat visible subconjunctival pigmented tissue within the sites of the previous surgical filtration blebs. In all three cases, there was an immediate and significant decrease in intraocular pressure associated with reestablishment of the filtration bleb (from 44 to 16 mm Hg in Case 1, from 40 to 15 mm Hg in Case 2, and from 25 to 12 mm Hg in Case 3). Long-term follow-up showed well controlled intraocular pressures without glaucoma medications (Case 1, 5 mm Hg after 18 months; Case 2, 17 mm Hg after one year; and Case 3, 9 mm Hg after five months).
三名患者（一名15岁女孩、一名45岁女性和一名61岁女性）此前接受的全层滤过手术曾取得成功，但瘘管部位出现色素沉着组织，尽管采用了最大耐受量的药物治疗，眼压仍无法控制。第一名和第二名患者的滤过手术分别在术后两年和四年自然失败。第三名患者的滤过泡在成功控制眼压六年之后，于白内障摘除术后两个月失效。通过结膜应用氩激光治疗先前手术滤过泡部位可见的结膜下色素沉着组织。在所有三例中，眼压立即显著下降，滤过泡重新形成（病例1从44毫米汞柱降至16毫米汞柱，病例2从40毫米汞柱降至15毫米汞柱，病例3从25毫米汞柱降至12毫米汞柱）。长期随访显示，无需使用青光眼药物眼压就能得到良好控制（病例1，18个月后为5毫米汞柱；病例2，一年后为17毫米汞柱；病例3，五个月后为9毫米汞柱）。
