To determine functional and anatomic response of 577 nm micro-pulsed photo stimulation in diabetic patients with diffuse diabetic macular edema (DME) and foveal leakage.
Fifty-eight eyes of 78 diabetic patients with DME were treated with yellow diode laser (577 nm) suited for micropulse treatment in macular area. ETDRS best corrected visual acuity, High definition optical coherence tomography to determine central macular thickness, Fluorescein angiography (FA) and Mean central retinal sensitivity measured through microperimetry were performed at basal, 1,3,6 and 9 months after a single treatment.
Central macular thickness decreased by 180 μm at 6 months with an increase in visual acuity of 6 ETDRS letters and macular sensitivity improved. Laser lesions were not observed neither clinically nor on FA examination.
Use of micro-pulsed macular photo stimulation may be a selective alternative to stop progress and improve vision in DME with minimal or null thermal damage to the retina.
