ObjectiveTo evaluate the effect of intravitreous injection with triamcinolone acetonide (TA) on macular edema.MothodHaving been examined by ophthalmoscopy, optic coherent tomography (OCT), retinal thickness analyzer (RTA), and fundus fluorescein angiography (FFA), 33 patients (37 eyes) with diffused and (or) cystoid macular edema caused by diabetes and retinal venous occlusion were intravitreously injected with 0.1 ml triamcinolone acetonide (40 mg/ml). During 1-9 month followup period, the visual acuity, intraocular pressure, inflammatory extent, manifestation of lens and fundus were observed, the retinal thickness was examined by OCT and RTA, and vascular leakage were detected by FFA.ResultsMacular thickness was (244.07±118.80), (195.53±57.70), and (181.42±54.79) μm respectively 1, 2, 3 months after treatment; while macular thickness was (724.35±227.41) μm before the treatment. The difference was statistically significant （t =10.72, 12.84, 13.90; P lt;0.001）. The visual acuity was 0.39±0.19, 0.45±0.24, and 0.43±0.21 respectively, comparing with the visual acuity before the treatment (0.20±0.16), the difference was statistically significant （t =4.445, 4.349, 3.474; P lt;0.001, lt;0.001, 0.03）；The result of FFA showed less leakage of fluorescein and proliferative lesion. Four pateints had the ocular pressure ≥25 mm Hg (1 mm Hg=0.133 kPa) in 9 who had ≥20 mm Hg. Recurrence of macular edema was found in 4 eyes of 3 patients 4 and 6 months after the treatment, respectively. No infection or aggravation of lenticular turbidness occurred.ConclusionIntravitreous injection with TA can be used to treat macular edema due to diabetes and retinal venous occlusion, and recurrence of macular edema or increase of intraocular pressure may occur in some patients.(Chin J Ocul Fundus Dis, 2005,21:205-208)
Objective To evaluate the efficacy and safety of local triamcinolone combined with conventional interventional therapy in the treatment of benign airway stenosis. Methods PubMed, Cochrane Library, EMbase, Web of science, wanfang, VIP and China National Knowledge Infrastructure were searched by computer between the establishment of the database and August, 2019, and all literatures on the local treatment of benign airway stenosis using triamcinolone combined with conventional interventional therapy were searched. According to inclusion and exclusion criteria, 2 researchers screened the literatures and performed the data extraction and methodological quality evaluation. Meta-analysis was performed with Revman5.2 and Stata software. Results In total, nine randomized controlled trials were included in this meta-analysis, including 449 patients with airway stenosis. The total result showed that in the comparison of short-term efficacy, there were no statistically significant differences in breathability score (SMD=–0.16, 95%CI –0.45 - 0.13, P=0.27), airway diameter (SMD=0.14, 95%CI –0.13 - 0.41, P=0.30), and cross-sectional stenosis rate (SMD=–0.01, 95%CI –0.36 - 0.34, P=0.96) between the treatment group and the control group. In the comparison of long-term efficacy, the breathability score (SMD=–2.53, 95%CI –3.78 - –1.28, P<0.05), airway diameter (SMD=1.31, 95%CI 0.83 - 1.78, P<0.05), cross-sectional stenosis rate (SMD=2.58, 95%CI: 2.11~3.08, P<0.05), and FEV1(SMD=0.42, 95%CI 0.13 - 0.70, P=0.004) of patients in the treatment group were all better than those in the control group. But in terms of adverse reactions, the incidence of bleeding in the airway between two groups was similar (RR=2.00, 95%CI 0.88 - 4.52, P=0.10), other adverse reactions such as blood glucose and plasma cortisol levels were mild, which can be relieved symptomatically. Conclusion Current evidence suggests that topical triamcinolone combined with conventional interventional therapy for benign airway stenosis has a better long-term clinical efficacy with fewer adverse reactions and better overall patient tolerance, which has clinical application value
ObjectiveTo investigate the efficacy and safety of intravitreous injection with triamcinolone acetonide (TA) for cystoid macular edema (CME) due to central retinal vein occlusion (CRVO).MethodsFourteen eyes of 14 patients with CME due to CRVO underwent intravitreous injection with 0.1 ml TA (40 mg/ml). Best-corrected visual acuity, intraocular pressure (IOP), slitlamp examinaion, fundus fluorescein angiography, and optical coherence tomography (OCT) were performed on the patients before and after the injection. The follow-up period was 10-22.4 months, with the mean of 15.9 months.ResultsThe average visual acuity was 0.1 before the treatment; while 1 month and 3 months after the injection, the visual acuity of all of the patients improved, including ≥0.2 in 71.43% and 63.6% of the patients, respectively, and ≥0.5 in 429% and 27.3%, respectively. After then, the visual acuity of some patients decreased, and in the final visit, 4 eyes (28.6%) had a visual acuity of ≥0.2, and 1 eye (7.1%) of ≥0.5. Compared with that before the treatment, the visual acuity of 10 (71.4%) eyes improved and 4 (28.6%) eyes declined. One month after the treatment, the macular edema disappeared in 10 eyes (71.4%) and alleviated in 4 (28.6%). In the final visit, macular edema disappeared in 4 eyes, alleviated in 9, and aggravated in 1. In the follow-up duration, high IOP［22.3-40.1 mm Hg (1 mm Hg=0.133 kPa)］. In the final visit, posterior subcapsular cataract was found in 7 eyes.ConclusionIntravitreous injection with TA may be effective in reducing CME and enhancing the visual acuity in a short term with high IOP in some eyes. In the long-term follow-up period, the rate of recurrence of CME and incidence of posterior subcapsular cataract is high. (Chin J Ocul Fundus Dis, 2005,21:213-216)
