The treatment of the clinically significant macular edema in patients with diabetic maculopathy by the intravitreal administration of corticosteroids and antiangiogenic factors requires rapid and more accurate investigation methods aimed at following up the dynamic evolution of the structural parameters of the retina.

The purpose of the study is to compare the outcome of OCT parameters for each group (Group A treated by intravitreal administered triamcinolone acetonide and Group B treated by intravitreal administered triamcinolone acetonide in combination with bevacizumab).

Methods involved the selection of cases, dynamic measurements of the retina structures, so that, at the end, the data from the two groups of patients could be compared.

The results showed a positive development in the short and medium term in both groups of patients.
