To assess the safety and efficacy of combined cataract extraction, posterior chamber intraocular lens placement, pars plana vitrectomy, fluocinolone acetonide intravitreal implant (Retisert), and Ahmed valves with pars plana tube (CPR-PT) in eyes with chronic, posterior, noninfectious uveitis.
Retrospective study of patients who underwent CPR-PT. Outcome measures included visual acuity, intraocular pressure, inflammation, and complications.
Eight eyes were included, with a mean follow-up of 18 months. Mean visual acuity improved from 1.89 to 0.14 logMAR (Snellen, counting fingers at 2 ft [0.6 m]) to 20/30; P=.01). Mean intraocular pressure remained stable at 16 to 17 mm Hg (P=.35). The number of glaucoma medications per eye decreased from 2.9 to 0.25 (P=.01). Systemic prednisone therapy was discontinued in all patients by 9 months postoperatively. Inflammation was well controlled in all eyes.
The CPR-PT procedure allows rapid visual rehabilitation without major short-term complications.
评估白内障摘除联合后房型人工晶状体植入、玻璃体切除、氟轻松醋酸酯玻璃体内植入（Retisert）以及带扁平部引流管的艾哈迈德引流阀（CPR-PT）在慢性后部非感染性葡萄膜炎患者眼中的安全性和有效性。
对接受CPR-PT手术的患者进行回顾性研究。观察指标包括视力、眼压、炎症及并发症。
纳入8只眼，平均随访18个月。平均视力从1.89（Snellen视力表，2英尺[0.6米]处数指）提高到20/30，logMAR视力从0.14提高到0.01（P = 0.01）。平均眼压稳定在16至17毫米汞柱（P = 0.35）。每只眼使用的青光眼药物数量从2.9种减少到0.25种（P = 0.01）。术后9个月时所有患者均停用全身泼尼松治疗。所有眼的炎症均得到良好控制。
CPR-PT手术可实现快速视力恢复，且无严重短期并发症。
