Figure 2: Light micrograph of the retina with DR + LLLT. (a) 1 week there was marked disorganization of photoreceptors, vacuolization in the OPL (yellow arrows), thickened basement membrane of the capillaries in the nerve fiber layer (red arrow). (b) 2 weeks showing edema of the cytoplasm of pigment epithelium layer and slight disorganization in PRL. (c) 4 weeks: Slight disorganization in PRL. (d) 6 weeks showed improved retina with no deviation from the control. (Toluidine blue, scale bar: 20 μm). DR: Diabetic retinopathy, LLLT: Low-level laser therapy, OPL: Outer plexiform layer, PRL: Photoreceptor layer, RPE: Retinal pigmented epithelium
