Figure 3: Burn Characteristic for Direct/Grid Photocoagulation Modified-ETDRS Technique: (a) Treatment Area Limits: 500–3000μ superiorly, nasally, and inferiorly and 500–3500μ temporally from the macular center. No burns are placed within 500μ of disc. (b) Identifying Treatment Area: All areas with diffuse leakage or nonperfusion within the area described in (a). (c) Focal/Direct Treatment: Directly treat all leaking microaneurysms in areas of retinal thickening until change in microaneurysms color. Burn Size: 50μ. Burn Duration: 0.05–0.1 s. (d) Grid Treatment: Burn Size: 50μ. Burn Duration: 0.05–0.1 s. Burn Intensity: Barely visible (light gray) Burn Separation: 2 visible burn widths apart. Wavelength (Grid and Focal Treatment) Green to yellow wavelengths Green to yellow wavelengths. Modified-ETDRS: Modified-Early Treatment Diabetic Retinopathy Study
