目的：分析慢性泪囊炎患者鼻内镜下泪囊鼻腔造瘘口术后的远期肉芽增生情况，评价物理清除联合曲安奈德（triamcinolone acetonide，TA）局部注射治疗慢性泪囊炎鼻内镜术后造瘘口肉芽组织增生的效果。方法：回顾性分析接受鼻内镜手术的慢性泪囊炎患者98例115眼。随访收集术后造瘘口肉芽组织增生发生情况，分析肉芽增生与无肉芽增生患者的临床特征。对有肉芽增生的患者26例31眼，根据治疗方式分为物理清除联合TA局部注射组13例16眼和单纯物理清除组13例15眼，比较2组间治疗有效率。结果：鼻内镜术后造瘘口肉芽增生病例共31眼（26.96%）。物理清除联合TA组的治愈率、好转率分别为93.75%、6.25%，物理清除组相应为60%、33.33%。组间比较差异有统计学意义（P < 0.05）。结论：物理清除联合TA局部注射治疗泪囊炎鼻内镜术后造瘘口肉芽组织增生安全、有效。

Objective: This study aimed to analyze the formation of ostium granulomas following endonasal endoscopic dacryocytostomy (DCR) in patients with chronic dacryocystitis and to evaluate the efficacy of excision combined with triamcinolone (TA) injection for treating ostium granulosis after endoscopic dacryocystorhinostomy. Methods: A restrospective analysis was conducted on 98 patients (115 eyes) with chronic dacryocystitis who underwent endoscopic dacryocystorhinostomy.  Postoperative growth of the ostium granulomas was monitored, and clinical characteristics were compared between patients with and without ostium granulomas. Among these, 26 cases (31 eyes) of ostium granuloma were identified and randomly assigned to either an excision combined with triamcinolone injection group (13 cases with 16 eyes) or excision-only group (13 cases with 15eyes) based on the treatment method. The effective rates between two groups was compared. Results: Ostium granulomas occurred in 31 eyes (26.96%). The cure rate and improvement rate in the excision combined with TA group were 93.75% and 6.25%, respectively, whereas in the excision-only group, they were 60% and 33.33%. These differences were statistically significant (P < 0.05).  Conclusions: Excision combined with intralesional triamcinolone acetonide injections proved effective in promoting the regression of ostium granuloma after DCR.

目的：研究玻璃体腔注射曲安奈德(triamcinolone acetonide,TA)和雷珠单抗(Lucentis)治疗视网 膜中央静脉阻塞(central retinal vein occlusion,CRVO)的黄斑水肿的疗效。方法：配对病例对照研究。将2013年1月至2015年6月，在我院因CRVO并发黄斑水肿而接受玻璃体腔注射TA或Lucentis 的患者，根据患者基线水平的最佳矫正视力(best-corrected visual acuity,BCVA)(logMAR视力)和黄斑中心厚度(central macular thickness,CMT)将两组患者进行配对，选出12对患者，主要的观察 指标为随访1年时两组患者的BCVA和CMT。结果：TA组患者的BCVA由基线时的0.78±0.12提高到 0.55±0.24(P=0.005),CMT由基线时的(598.92±192.67) μm减少到(258.28±75.38) μm (P=0.002)。Lucentis组患者的BCVA由基线时的0.78±0.11提高到0.48±0.21(P=0.002), CMT由基线时的 (591.75±181.68) μm减少到(281.17±63.08) μm (P=0.002)。TA组和Lucentis组患者基线及最终的 BCVA和CMT直接均无显著差异。TA组的平均注药次数为(2.4±0.9)次，Lucentis组为(4.0±1.6)次， 两组有统计学差异(P=0.012)。结论：玻璃体腔注射TA或Lucentis均能减轻CRVO所致的黄斑水肿并提高视力，两者的疗效并无显著差异。TA的平均注射次数比Lucentis组少，但是TA更容易引起眼压升高。应该根据患者的综合情况制定个性化的治疗方案。

Objective: To compare the efficacy of intravitreal injections of triamcinolone acetonide (TA) and that of ranibizumab for macular edema secondary to central retinal vein occlusion (CRVO). Methods: In a retrospective assessment 12 TA-treated patients and 12 ranibizumab-treated ones with macular edema after CRVO were pairmatched according to initial best-corrected visual acuity (BCVA) and central macular thickness (CMT). BCVA and CMT were the main endpoints. Results: The initial BCVA of 0.78±0.12 increased significantly to 0.55±0.24 in the TA-treated patients (P=0.005). And the initial CMT of (598.92±192.67) μm decreased significantly to (258.28±75.38) μm (P=0.002). In the ranibizumab-treated patients, the initial BCVA of 0.78±0.11 increased significantly to 0.48±0.21 (P=0.002) and the initial CMT of (591.75±181.68) μm decreased significantly to (281.17±63.08) μm (P=0.002). There was no significance between the initial and final BCVA and CMT of TAtreated patients and ranibizumab-treated patients. Conclusion: Both treatments decreased the CMT and induced an improvement in BCVA from baseline.
