Brief Summary

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

The goal of this clinical trial es to learn about the short term effects of intravitreal dexamethasone implant (IDI) in patients with refractory diabetic macular edema. The main question it aims to answer is:

How fast does the diminishing in central retinal thickness has statistical significance after IDI in patients with refractory diabetic macular edema? Patients will be evaluated by OCT before and after the implant.

Detailed Description

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

Patients were evaluated at baseline, 2 hours, 3 hours, 24 hours, 1 week and 1 month post IDI
