Background The aqueous flare is obvious in uveitic glaucomatous eye due to the damage of blood-aqueous barrier,especially following intraocular surgery.How to quantitatively determine the aqueous flare is important for us to understand the severity of inflammatory response.Objective This study was to assess inflammatory response following Ahmed glaucoma valve implantation in uveitic glaucomatous eye.Methods A nonrandomized controlled study was carried out under the approval of Ethic Committee of Zhongshan Ophthalmic Center of Sun Yat-sen University.Twenty-nine eyes of 29 subjects with refractory glaucoma were enrolled this hospital from October 2011 through July 2012.The patients were divided into the uveitic glaucoma group (10 eyes) and the other refractory glaucoma group (19 eyes) with the matched demography,and Ahmed glaucoma valve implantation was performed on all the eyes under the informed consent of each patient.The aqueous flare value was determined with FC-2000 flare-cell photometry and intraocular pressure (IOP) was measured with Goldmann tonometer before surgery and 1 day,3 days,1 week,2 weeks,1 month and 3 months after surgery.The outcomes were compared between the two groups,and the correlation of aqueous flare value with IOP was analyzed.Results In the uveitic glaucoma group,the aqueous flare values were 21.10 (10.50,38.58) photoparticles/ms,88.00 (23.55,168.63) photoparticles/ms and 29.90 (8.90,65.18)photoparticles/ms 1 day,3 days and 1 week after surgery,which were significantly higher than 13.53 (7.60,24.00) photoparticles/ms before surgery (all at P＜0.01).The same trend was found in the other refractory glaucoma group.In addition,the aqueous flare value was higher in the uveitic glaucoma group than that in the other refractory glaucoma group in 3 months after surgery (q=-3.445,P＜0.01).No significant differences were seen in IOP between the two groups at various time points (all at P＞0.05).Also,no significant correlations were seen between IOP and aqueous flare value in all patients at various time points (preoperation:rs =0.136,P =0.481; postoperative 1 day:rs =0.019,P =0.922 ; postoperative 3 days:rs =-0.035,P =0.858 ; postoperative 1 week:rs =0.317,P=0.094; postoperative 2 weeks:rs =0.034,P =0.861 ; postoperative 1 month:rs =-0.094,P =0.628 ; postoperative 3 months:rs =0.065,P =0.738).Conclusions FC-2000 flare-cell photometry can reflect the inflammatory reaction of the anterior chamber following Ahmed glaucoma valve implantation in various types of refractory glaucomatous eyes.The postoperative inflammatory response is more serious and lasting in uveitic glaucomatous eye.%背景 葡萄膜炎继发性青光眼患者由于葡萄膜的炎症而导致血-房水屏障的破坏,局部手术的创伤刺激可加重炎症反应,对术眼前房炎症反应进行定量检测可监测眼部反应程度. 目的 探讨葡萄膜炎继发性青光眼患者行Ahmed青光眼引流阀植入术后前房内炎症反应是否重于其他类型的难治性青光眼.方法 采用前瞻性非随机对照的病例对照研究方法,于2011年10月至2012年7月纳入在中山大学中山眼科中心确诊的难治性青光眼29例29眼,分为葡萄膜炎继发性青光眼组(10眼)及其他类型的难治性青光眼组(19眼),2个组间术眼术前性别、年龄、眼压及房水闪辉值等基线特征匹配.所有患者均接受Ahmed房水引流阀植入术并随访3个月,记录术前、术后1d、3d、1周、2周、1个月和3个月术眼的眼压,同时采用FC-2000激光蛋白细胞检测仪定量测定术眼的房水闪辉值,以光粒子数/ms表示.比较2个组间房水引流阀植入术后房水闪辉值的不同,对术眼手术前后眼压值变化与房水闪辉值变化的关系进行分析. 结果 葡萄膜炎继发性青光眼组术后1d、3d和1周房水闪辉值分别为[21.10 (10.50,38.58)]、[88.00(23.55,168.63)]和[29.90(8.90,65.18)]光粒子数/ms,均明显高于术前的[13.53(7.60,24.00)]光粒子数/ms,差异均有统计学意义(均P＜0.01),术后1个月和3个月房水闪辉值分别为[6.45 (4.70,13.50)]光粒子数/ms和[8.95 (6.23,18.20)]光粒子数/ms,均低于术前值,差异均有统计学意义(均P＜0.01);其他类型青光眼组遵循同样的趋势.术后3个月葡萄膜炎继发性青光眼组术眼房水闪辉值明显高于其他类型青光眼组,差异有统计学意义(q=-3.445,P＜0.01).术后2个组间眼压的比较差异无统计学意义(P＞0.05).所有患者术眼术后眼压值均逐渐下降,术前及术后1d、3d、1周、2周、1个月和3个月术眼眼压与前房闪辉值间均无明显相关性(rs =0.136,P=0.481;rs=0.019,P=0.922;rs =-0.035,P=0.858;r,=0.317,P=0.094;rs=0.034,P=0.861;rs=-0.094,P=0.628;rs=0.065,P=0.738). 结论 FC-2000激光蛋白细胞检测仪检测证实Ahmed房水引流阀植入术可导致术眼术后早期的前房炎症反应,葡萄膜炎继发性青光眼患者术后炎症反应的恢复较缓慢,术后3个月时房水闪辉值仍高于其他类型的难治性青光眼.
