Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To determine the efficacy and safety of intravitreal triamcinolone acetonide for refractory diabetic macular edema.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Overall 80% of diabetic patients with low vision are in the nonproliferative stage and the main cause of decreased visual acuity is macular edema.

According to the early treatment diabetic retinopathy study (ETDRS), the treatment of choice for diabetic macular edema (DME) is laser therapy, which may be neither effective nor curative in some patients.There are many cases which are refractory to laser treatment or not suitable candidates for it.

Corticosteroids might have a beneficial effect on DME. They have been used with different doses and routes (periocular,intravitreal,and slow released implants) for a variety of retinal diseases.

Recently, a few prospective randomized studies, concerning the effect of intravitreal triamcinolone acetonide (IVT) on DME have been published. In their two-year results, Gillies et al. concluded that IVT improved vision and reduced macular thickness in eyes with refractory diabetic macular edema. They showed that this beneficial effect persisted for up to 2 years with repeated treatment.

We also conducted a randomized placebo-controlled clinical trial to determine the safety and efficacy of IVT for intractable DME. Besides, we tried to evaluate the effect of this intervention on angiographic findings of these patients.
