背景 选择性激光小梁成形术(SLT)治疗原发性开角型青光眼(POAG)的安全性和有效性已得到人们广泛的认同,但迄今为止SLT治疗闭角型青光眼的研究较少,其效果和安全性尚待临床观察证实.目的 评价SLT治疗残余原发性闭角型青光眼(PACG)的疗效及安全性.方法 采用病例观察性研究设计.共纳入经激光周边虹膜成形术和/或激光虹膜周边切除术治疗后前房角开放但眼压不能降至正常的闭角型青光眼患者23例33眼,术前平均眼压(24.78±4.48)mmHg,日平均用药指数(1.62±0.66)分.所有眼的前房角能看到小梁网的范围约180°.用Q开关倍频Nd:YAG激光机在患眼开放的前房角照射小梁网,在180°范围内照射70 ~80点.术后继续使用术前的降眼压药物,术后随访9个月,定期复查眼压、视力、眼前节炎症反应和房水流畅系数测定值,并用前房角镜检查房角的开放情况.结果 本组术眼术后1d,1周,1、3、6、9个月的平均眼压分别为(18.78±4.87)、(18.83±3.95)、(19.78±4.48)、(19.63±3.68)、(19.11±3.36)、(21.17±3.14)mmHg,与术前眼压值(24.78±4.48)mmHg比较,术后1~9个月明显下降,差异均有统计学意义(P<0.05).各时间点患眼日平均用药指数分别为(1.63±0.85)、(1.23±1.01)、(1.25±0.98)、(1.21±1.02)、(1.22±0.86)、(1.69±0.53)分,术后1周,1、3、6个月与术前值的(1.62±0.66)分比较,差异均有统计学意义(P=0.020、0.026、0.020、0.031).术后即刻可见睫状体充血和前房闪辉,1周后自然消退.16眼术前和术后3个月的平均房水流畅系数(C值)分别为0.11±0.09和0.23±0.15,差异有统计学意义(P=0.002).结论 SLT能够安全有效地降低部分闭角型青光患者的眼压,但其前提是必须有1/2周的虹膜小梁角是开放的.
揹景 選擇性激光小樑成形術(SLT)治療原髮性開角型青光眼(POAG)的安全性和有效性已得到人們廣汎的認同,但迄今為止SLT治療閉角型青光眼的研究較少,其效果和安全性尚待臨床觀察證實.目的 評價SLT治療殘餘原髮性閉角型青光眼(PACG)的療效及安全性.方法 採用病例觀察性研究設計.共納入經激光週邊虹膜成形術和/或激光虹膜週邊切除術治療後前房角開放但眼壓不能降至正常的閉角型青光眼患者23例33眼,術前平均眼壓(24.78±4.48)mmHg,日平均用藥指數(1.62±0.66)分.所有眼的前房角能看到小樑網的範圍約180°.用Q開關倍頻Nd:YAG激光機在患眼開放的前房角照射小樑網,在180°範圍內照射70 ~80點.術後繼續使用術前的降眼壓藥物,術後隨訪9箇月,定期複查眼壓、視力、眼前節炎癥反應和房水流暢繫數測定值,併用前房角鏡檢查房角的開放情況.結果 本組術眼術後1d,1週,1、3、6、9箇月的平均眼壓分彆為(18.78±4.87)、(18.83±3.95)、(19.78±4.48)、(19.63±3.68)、(19.11±3.36)、(21.17±3.14)mmHg,與術前眼壓值(24.78±4.48)mmHg比較,術後1~9箇月明顯下降,差異均有統計學意義(P<0.05).各時間點患眼日平均用藥指數分彆為(1.63±0.85)、(1.23±1.01)、(1.25±0.98)、(1.21±1.02)、(1.22±0.86)、(1.69±0.53)分,術後1週,1、3、6箇月與術前值的(1.62±0.66)分比較,差異均有統計學意義(P=0.020、0.026、0.020、0.031).術後即刻可見睫狀體充血和前房閃輝,1週後自然消退.16眼術前和術後3箇月的平均房水流暢繫數(C值)分彆為0.11±0.09和0.23±0.15,差異有統計學意義(P=0.002).結論 SLT能夠安全有效地降低部分閉角型青光患者的眼壓,但其前提是必鬚有1/2週的虹膜小樑角是開放的.

Background Selective laser trabeculoplasty(SLT)has been widely accepted for the treatment of open-angle glaucoma.However,there are few reports about its application in treating angle-closure glaucoma so far.Objective This study was to clinically evaluate the safety and efficacy of selective laser trabeculoplasty for primary angle-closure glaucoma with opened anterior angle follow-up surgery.Methods A case-observational design was adopted in this study.A total of 33 eyes from 23 angle-closure glaucomatous patients with opened 180° angle were enrolled.All the patients understood this trial and written informed consent was obtained prior to the medical treatment.The average preoperative intraocular pressure(IOP)and number of medication were(23.07±4.01)mmHg and 1.52±0.66,respectively.A frequency doubled Q-switched Nd:YAG laser was used to irradiate the trabecular meshwork with 70-80 laser spots over 180°.The same preoperative anti-glaucoma drugs were topically administered during the follow-up period.Visual acuity,IOP,slit lamp examination,gonioscopy and the coefficient of outflow facility were regularly assessed and performed after laser surgery.Results The IOP values of the 33 eyes were(18.78±4.87)mmHg,(18.83±3.95)mmHg,(19.78±4.48)mmHg,(19.63±3.68)mmHg,(19.11±3.36)mmHg,and(21.17±3.14)mmHg 1 day,l week,and 1,3,6,9 months after operation,showing significant decline in comparison with preoperation(P<0.01).The mean drug uses were 1.63±0.85,1.23±1.01,1.25±0.98,1.21±1.02,1.22±0.86,and 1.69±0.53 at the same time point after operation,respectively,and significant differences were found 1 week,1,3,6 months in postoperation in comparison with preoperation(P =0.020,0.026,0.020,0.031).Ciliary congestion and aqueous flare naturally disappeared 1 week after surgery.The coefficients of outflow facility were 0.11±0.09 and 0.23±0.15,respectively at pretreatment and 3 months after SLT with a statistically significant difference (P=0.002).Conclusions Selective laser trabeculoplasty is effective and safe for angle-closure glaucoma.However,it is essential to have 1/2 circle of anterior chamber open for SLT in angle-closure glaucoma.
