ABSTRACTIntroduction: macular edema is the most common cause of decreasing central visual acuity in patients with diabetic retinopathy; its origin is multifactorial. Central visual loss depends on retinal exudation and duration of the disease.
Objective: to reflect changes in the microperimetry after the use of triamcinolone acetonide injection in a patient with moderate non-proliferative diabetic retinopathy and macular edema clinically significant.
Clinical case: a patient with macular edema clinically significant associated with moderate non-proliferative diabetic retinopathy was evaluated through visual acuity test with best correction, biomiscroscopy of the anterior and posterior segment, indirect ophthalmoscopy, tonometry, microperimetry, automatic protocol to the macula of 12 degrees, 45 macular points was used. Eyeground examination and biomiscroscopy of the posterior segment showed intraretinal rounded bleeding in four quadrants, beaded venae in a quadrant, intraretinal microvascular abnormalities in two quadrants, thick and tortuous vessels, macula with hard exudate in posterior pole and microaneurysms outside of the foveolar avascular zone, in circinate forms, and scattered microhemorrhagia.
Conclusions: the patient was treated with focal macular photocoagulation and intravitreal triamcinolone acetonide injection; visual acuity improved so as the parameters in microperimetry over a period of a month.
