玻璃体腔内注射曲安奈德治疗糖尿病性黄斑水肿的临床疗效观察

目的评价玻璃体内注射曲安奈德（TA）治疗糖尿病性黄斑水肿的疗效与安全性。方法回顾性分析自2011年12月至2013年3月在我院眼科确诊的68例（84只眼）糖尿病性视网膜病变黄斑水肿患者,行玻璃体腔内注射TA（40 mg/l）0.1 ml,随访3-15个月,平均8.9个月,观察BCVA、眼压、晶状体、炎症反应,OCT检测黄斑中心凹视网膜厚度,FFA检查观察黄斑部毛细血管渗漏情况。结果 68例（84只眼）患者治疗后视力均有不同程度提高,黄斑水肿减轻。治疗后1、2、3个月平均视力分别为0.39±0.17、0.47±0.20、0.37±0.18,与治疗前平均视力0.19±0.13比较,差异有统计学意义（t值分别为4.482、5.733、4.051,P﹤0.05）。黄斑中心凹视网膜平均厚度分别为（198.12±28.94）μm、（183.66±24.66）μm、（225.96±50.90）μm,与治疗前平均视力（596.35±127.37）μm比较,差异有统计学意义（t值分别为15.253、15.934、13.227,P﹤0.05）。FFA检查显示治疗后荧光渗漏明显减少。9例（9只眼）眼压≥21 mm Hg,其中1例（1只眼）为34.2 mm Hg。5例（7只眼）4-7个月后黄斑水肿复发。2例（2只眼）8个月、12个月后晶状体后囊混浊明显。无感染发生。结论玻璃体腔内注射TA能有效改善糖尿病性黄斑水肿,提高视力,但部分患眼出现黄斑水肿复发、眼压升高,部分出现晶状体混浊加重。     

The combination of phacoemulsification surgery and intravitreal triamcinolone injection in patients with cataract and diabetic macular edema

Purpose

To assess the safety and efficiency of combined phacoemulsification (PHACO) surgery and intravitreal triamcinolone (IVTA) injection with or without macular grid laser photocoagulation in patients with cataract and diabetic macular edema.

Material and methods

This prospective study included 41 eyes of 36 diabetic patients with cataract and coexisting clinically significant macular edema (CSME). After PHACO and IVTA injection eyes were divided into two groups: the laser and IVTA group (Group 1) and only IVTA group (Group 2). Preoperative and postoperative best corrected visual acuity (BCVA), central macular thickness (CMT), and intraocular pressure (IOP) were recorded. Paired sample t-test was used to compare data in the groups and C square test for qualitative variables.

Results

Postoperative BCVA was significantly higher than the initial BCVA during the follow-up period in both groups (p < 0.01). The BCVA 6 months after surgery was significantly higher in group 1 than in group 2 (p < 0.01). There was no statistically significant difference in IOP between two groups preoperatively and postoperatively during the follow-up period (p > 0.05). There was no statistically significant difference between both groups in mean CMT preoperatively and 2nd week, 2nd month and 3rd month after surgery (p > 0.05). The mean CMT 6 months after surgery was statistically significantly lower in group 1 than in group 2 (p < 0.01).

Conclusions

PHACO surgery combined with IVTA injection improves BCVA and provides a decrease in CMT in diabetic patients with CSME. Additional macular grid laser photocoagulation after surgery helps to preserve this improvement in BCVA and decrease in CMT.     

Two-year results of intravitreal triamcinolone acetonide injection for the treatment of diabetic macular edema

Purpose To investigate 2-year results of intravitreal triamcinolone acetonide injection for the treatment of diffuse diabetic macular edema unresponsive to previous laser photocoagulation. Method The study included 75 eyes of 75 diabetic patients with clinically significant diffuse macular edema that had failed to respond to previous laser photocoagulation. An intravitreal injection of triamcinolone acetonide at the dose of 4 mg/0.1 ml was administered. Best-corrected visual acuity was measured as the logarithm of the minimum angle of resolution (logMAR), and central macular thickness was obtained by optical coherence tomography at each visit. Intraocular pressure and lenticular status were also evaluated. Differences among measurements were evaluated by Friedman two-way analysis of variance by ranks. Mean follow-up period was 24.7 ± 5.9 months. Results The mean central macular thickness, which was obtained 3 days, 1 month, 3 months, 6 months, 9 months, 12 months, 18 months and 24 months postoperatively, was significantly different from the baseline measurement (P < 0.001). Mean best-corrected logMAR visual acuity improved significantly from baseline at the 1- month and 3-month follow-up intervals (P < 0.05), but there was no significant change at the 6- month, 9-month, 12-month, 18-month or 24-month follow-up periods (P > 0.05). During the follow-up, 29 (38.7%) eyes received re-injection of intravitreal triamcinolone. Twenty-one (28%) eyes developed intraocular pressure values higher than 21 mmHg, and 18 (24%) eyes developed cataract. Thirteen (17.3%) eyes required cataract and/or glaucoma surgery. Conclusions In refractory diabetic macular edema, intravitreal triamcinolone effectively reduces foveal thickness and improves visual acuity in the short term, but with the extended follow-up, the number of recurrences and steroid-related complications were shown to increase. Nevertheless, it may be a therapeutic option in some patients that do not respond to previous laser photocoagulation.

Comparison of the short-term effects of intravitreal triamcinolone acetonide and bevacizumab injection for diabetic macular edema

Purpose

To compare the short-term effects of intravitreal triamcinolone acetonide (IVTA) with those of intravitreal bevacizumab (IVB) injection for diabetic macular edema (DME).

Methods

The present retrospective, comparative case study included 58 eyes of 35 consecutive patients (IVTA group, 20 eyes; IVB group, 38 eyes) with DME. IVTA (4 mg) or IVB (1.25 mg) injection was performed under local anesthesia. The effects of injection for DME were evaluated using best-corrected visual acuity (BCVA), central macular thickness (CMT) by optical coherence tomography and intraocular pressure (IOP) by applanation tonometer. Patients underwent eye examinations, including BCVA, CMT, and IOP at pre-injection, 2, 4, and 8 weeks after injection.

Results

BCVA (logarithm of the minimum angle of resolution) ± SD at pre-injection, 2, 4, and 8 weeks after injection was 0.67 ± 0.40, 0.56 ± 0.35 (p = 0.033), 0.55 ± 0.33 (p = 0.041), and 0.43 ± 0.31 (p = 0.001) in the IVTA group and 0.51 ± 0.31, 0.42 ± 0.26 (p = 0.003), 0.43 ± 0.32 (p = 0.001), and 0.43 ± 0.27 (p = 0.015) in the IVB group, respectively. CMT (µm) ± SD at pre-injection, 2, 4, and 8 weeks after injection was 400.4 ± 94.9, 332.8 ± 47.4 (p = 0.002), 287.5 ± 49.1 (p = 0.007), and 282.5 ± 49.6 (p = 0.043) in the IVTA group and 372.6 ± 99.5, 323.2 ± 72.4 (p = 0.077), 360.9 ± 50.3 (p = 0.668), 368.2 ± 88.6 (p = 0.830) in the IVB group, respectively.

Conclusions

The effects of IVTA for BCVA were more favorable than were those of IVB and were consistent throughout the eight weeks after injection. IVTA significantly reduced CMT during the eight weeks after injection, while IVB did not.

A randomized, placebo-controlled clinical trial of intravitreal triamcinolone for refractory diabetic macular edema

Purpose To evaluate the effect of intravitreal triamcinolone acetonide (IVT) on refractory diabetic macular edema (DME). Methods In a prospective, placebo-controlled, randomized clinical trial, 88 eyes of 61 patients with clinically significant macular edema that would have responded unfavourably to laser photocoagulation were randomly assigned to two groups. The treatment group (45 eyes) received 4 mg IVT and the control group (43 eyes) received a placebo subconjunctival injection. The primary outcome was central macular thickness (CMT) measured by optical coherence tomography. Complete examination was repeated at 2 and 4 months post-intervention. Results The mean (SD) CMT before the intervention and at the 2- and 4-month follow-ups was 393 (151), 293 (109) and 362 (119) μm in the treatment group and 393 (166), 404 (134) and 405 (160) μm in the placebo group, respectively. The second month difference was significant (P = 0.01). The difference between visual acuity changes (0.15 logarithm of the minimum angle of resolution, logMAR) was significant at 2 months (P = 0.02) but reduced to 0.11 logMAR (P = 0.08) after 4 months. Reduction for hard exudates and petaloid pattern were significantly greater in cases at 4 months. Conclusions The therapeutic effect of IVT on DME is greatest at 2 months and decreases up to the fourth month post-intervention. However, in terms of cystoid macular edema and hard exudates, the effect is maintained up to 4 months.     

曲安奈德玻璃体腔内注射治疗糖尿病黄斑水肿

目的观察玻璃体腔内曲安奈德（triamcinolone acetonide，TA）注射治疗糖尿病黄斑水肿（diabetic macular edema，DME）的疗效并进行分析。方法21例29眼DME患者玻璃体腔内注射4mg TA，治疗前后均行视力、眼压、裂隙灯、荧光素眼底血管造影和光学相干断层扫描检查。治疗前视力手动-0．3，黄斑中心凹视网膜厚度283—941μm，视网膜厚度均值为（547．19±162.35）μm。随访3—6个月，对视力和视网膜厚度进行配对t检验。结果治疗后平均视力为0，35±0．27，3个月时最佳矫正视力可达0．9。视力提高3行以上者23眼，提高3行以内者5眼，不变者1眼。与治疗前比较，差异有统计学意义（P〈0．05）。视网膜厚度平均值为（301．27±165．89）μm，与治疗前相比，差异有统计学意义（P〈0．05）。因3个月后黄斑水肿复发，再次注药者5眼。无玻璃体出血、视网膜脱离和眼内炎等严重并发症。结论TA 4mg玻璃体腔内注射可以减轻DME，是一种有效可行的方法。对黄斑水肿复发的患者可考虑玻璃体腔内重复注药。但其远期疗效和并发症需进一步观察。[眼科新进展2007；27（3）：201-203]     

Diabetic macular edema before and after intravitreal triamcinolone injection

PURPOSE: To compare intravitreal triamcinolone acetonide (IVT) versus natural course in refractory diabetic macular edema. METHODS: In a prospective interventional case series, twenty five eyes with refractory DME which had been allocated to the sham group of a previous clinical trial underwent new examination and optical coherence tomography about 9 months after their first enrollment. Twenty eyes that met the inclusion criteria, visual acuity (VA) < 20/50 and central macular thickness (CMT) > 200 microm, were treated by 4 mg IVT. Evaluations were repeated at 2 and 4 months post-injection to imitate the similar examination intervals after sham injection. Corrected visual acuity and macular thickness changes following IVT were compared to the corresponding changes after sham injection (the natural course). RESULTS: Visual acuity changes within and between each period were not statistically significant. Visual acuity decreased 0.08 & 0.09 logMAR by 2 months and 0.06 & 0.04 logMAR by 4 months after sham and IVT injections, respectively. The changes of macular thickness after IVT and sham intervention were not meaningful either. However, the difference between thickness changes by 4 months (52+/-50 microm increase after sham vs. 262+/-115 microm reduction after IVT) was significant (P=0.014). CONCLUSIONS: Concerning macular thickness, IVT has beneficial effect on refractory diabetic macular edema as opposed to observation. However, considering visual acuity, it does not induce significant difference in comparison to the natural course of the disease.

Matrix γ-carboxyglutamate protein and Fetuin-A, in wet type age-related macular degeneration

AIM:To compare therapeutic effects of intravitreal triamcinolone acetonide (IVTA) versus intravitreal bevacizumab (IVB) injections for bilateral diffuse diabetic macular edema (DDME).METHODS: Forty eyes of 20 patients with bilateral DDME participated in this study. For each patient, 4 mg/0.1 mL IVTA was injected to one eye and 2.5 mg/0.1 mL IVB was injected to the other eye. The effects of injection for diabetic macular edema (DME) were evaluated using best-corrected visual acuity (BCVA), central macular thickness (CMT) by optical coherence tomography (OCT) and intraocular pressure (IOP) by applanation tonometer. Patients underwent eye examinations, including BCVA, CMT, and IOP at pre-injection, 1, 4, 8, 12 and 24wk after injection. During the follow-up, second injections were performed to eyes which have CMT greater than 400 µm at 12wk for salvage therapy.RESULTS: BCVA (logarithm of the minimum angle of resolution) at pre-injection, 1, 4, 8, 12 and 24wk after injection was 0.71±0.19, 0.62±0.23, 0.63±0.12, 0.63±0.13, 0.63±0.14 and 0.61±0.24 in the IVTA group and 0.68±0.25, 0.61±0.22, 0.60±0.24, 0.62±0.25, 0.65±0.26 and 0.59±0.25 in the IVB group, respectively. CMT (μm) at pre-injection, 1, 4, 8, 12 and 24wk after injection was 544±125, 383±96, 335±87, 323±87, 333±92, 335±61 in the IVTA group and 514±100, 431±86, 428±107, 442±106, 478±112, 430±88 in the IVB group respectively. Reduction ratios of mean CMT were 29% at 1wk, 38% at 4wk, 40% at 8wk, 38% at 12wk, and 38% at 24wk in the IVTA group. Second IVTA injections were performed to the 6 eyes (30%) at 12wk. Reduction ratios of mean CMT were 16% at 1wk, 17% at 4wk, 14% at 8wk, 7% at 12wk, and 16% at 24wk in the IVB group. Second IVB injections were performed to the 15 eyes (75%) at 12wk.CONCLUSION:This study showed earlier and more frequent macular edema recurrences in the eyes treated with bevacizumab compared with the ones treated with triamcinolone acetonide. Triamcinolone acetonide was found to provide more efficient and long-standing effect in terms of reducing CMT compared with the bevacizumab.

目的：：评价曲安奈德和贝伐单抗玻璃体腔注射治疗白内障术后黄斑水肿的疗效,为临床安全有效用药提供参考。方法：选择2012-03/2014-03在我院眼科确诊为黄斑水肿的患者92例92眼为研究对象,按照玻璃体腔注射用药不同,分为曲安奈德组44例44眼和贝伐单抗组48例48眼,术后随访9mo,比较两组患者在不同时间点的最佳矫正视力、黄斑中央视网膜平均厚度和眼内压情况。结果：术后随访9mo,两组患者术后的最佳矫正视力均比术前提高,但组间无统计学意义(P>0.05);经重复测量方差分析,两组患者的黄斑中央视网膜厚度无统计学意义(P>0.05)。曲安奈德组术后各时间点与术前的黄斑中央视网膜厚度差异具有统计学意义( t=9.16,8.27,5.44,5.87,4.62,P<0.05),贝伐单抗组术后各时间点的斑中央视网膜厚度均比术前降低,具有统计学意义( t=8.11,5.12,4.16,3.27,2.88,P<0.05);曲安奈德组有7例患者发生眼压升高,并发为青光眼,贝伐单抗组患者未见眼压异常。结论：曲安奈德和贝伐单抗均可提高黄斑水肿患者的矫正视力,改善毛细血管的渗漏情况,但贝伐单抗不会引起眼压升高,能避免其他并发症的发生,安全性更高。     

糖尿病黄斑水肿患者白内障术中玻璃体腔注射曲安奈德的临床观察

目的评价白内障超声乳化吸除及人工晶状体植入术中玻璃体腔内注射曲安奈德(TA)对伴有糖尿病黄斑水肿的白内障患者的疗效及安全性。方法 25例合并糖尿病黄斑水肿的白内障患者随机分为注药组、对照组,均采用标准的超声乳化白内障吸除及人工晶状体植入术。注药组13例患者术毕时,玻璃体腔内注射TA 4 mg/0.1 m L;对照组12例患者未进行玻璃体药物注射治疗。术后随访1~3个月,观察手术前、后(45±10)d的视力、黄斑中心凹视网膜厚度、眼压及并发症。结果所有患者术后视力较术前皆有提高,但仅有注药组视力改善与术前差异有统计学意义(P<0.05)。注药组术后视力优于对照组,差异有统计学意义(P<0.05)。术前和术后(45±10)d黄斑中心厚度:注药组术前比术后明显下降,差异有统计学意义(P<0.05)。注药组术后黄斑厚度明显低于对照组,差异有统计学意义(P<0.05)。对照组术后比术前视网膜厚度有所增加,差异无统计学意义(P>0.05)。2组间眼压差异无统计学意义(P>0.05);2组皆未观察到严重术后并发症。结论白内障超声乳化及人工晶体植入术中联合TA玻璃体腔注射术能够明显提高患者视力,减轻黄斑水肿,为后续观察和治疗创造条件。
