Effect analysis of intra-vitreous injection of Triamcinolone Acetonide for diabetic macular edema

Objective To observe the clinical curative effect and security of intra-vitreous injection of Triamcinolone Acetonide for diabetic macular edema. Methods 45 patients with diabetic macular edema were injected 40 mg/mL Triamcinolone Acetonide 0.1 mL in vitreous for treatment. The follow-up duration was 1 month and 3 months. The visual acuity, intraocular pressure and retinal thickness at the macular area were observed and compared before and after treatment. Results 1 month and 3 months after the injection, the mean extent of improvement of visual acuity was(0.41±0.19) and(0.45±0.21); while the decrease of retinal thickness at macula was(295.37 ±38.73) μm and(296.52± 39.46) μm. Compared with before treatment, the difference was significant(P 0.05). Intraocular pressure was in the normal range and complications were not found after treatment. Conclusion Triamcinolone Acetonide is effective and safe for diabetic macular edema.
