Conditions

Macular Edema

Interventions

The sample will consist of one eye of 48 diabetic volunteers with DME divided into 4 groups of 12 individuals randomized through a 1:1:1:1 sequential allocation. In the first group the anti-VEGF ranib
data will be computer generated and stored in a locked cabinet until the end of the study period. Volunteers and those responsible for data collection will be masked. Calculations based on the effect

Design outcomes

Primary

MeasureTime frame
To evaluate the corrected visual acuity of volunteers undergoing treatment for diabetic macular edema with intravitreal injection of anti-VEGF agents associated or not with a 4 mg/mL dexamethasone solution 90 days after the first intravitreal injection. Subjects treated with dexamethasone are expected to do at least 10% better than untreated subjects;To evaluate the macular thickness, through optical coherence tomography, of volunteers undergoing treatment for diabetic macular edema with intravitreal injection of anti-VEGF agents associated or not with a 4 mg/mL dexamethasone solution 90 days after the first intravitreal injection. Subjects treated with dexamethasone are expected to do at least 10% better than untreated subjects

Secondary

MeasureTime frame
To evaluate the corrected visual acuity of volunteers undergoing treatment for diabetic macular edema with intravitreal injection of anti-VEGF agents associated or not with dexamethasone 4 mg/mL solution one, three, seven, 30 and 60 days after the first intravitreal injection. . Subjects treated with dexamethasone are expected to do at least 10% better than untreated subjects;To evaluate the macular thickness, through optical coherence tomography, of volunteers undergoing treatment for diabetic macular edema with intravitreal injection of anti-VEGF agents associated or not with a 4 mg/mL dexamethasone solution one, three, seven, 30 and 60 days after the first intravitreal injection. Subjects treated with dexamethasone are expected to do at least 10% better than untreated subjects;To evaluate the intraocular pressure, through applanation tonometry, of volunteers undergoing treatment for diabetic macular edema with intravitreal injection of anti-VEGF agents associated or not with dexamethasone 4 mg/mL solution on one, three, seven, 30, 60 and 90 days after the first intravitreal injection. Subjects treated with dexamethasone are expected to have a similar outcome to untreated subjects
