Peripheral Neovascularization Beyond Extent of Panretinal Photocoagulation

These are wide angle images from OPTOS fluorescein angiography performed in a 65-year-old female patient with peripheral neovascularization in the setting of diabetic retinopathy. She has received panretinal photocoagulation (prp), however, the extent of her neovascularization occurs beyond the treated area. The yellow arrows indicate laser scars. The red arrows highlight the neovascularization. Green arrows show regions of capillary nonperfusion that lead to excess vascular endothelial growth factor production, which is the cause of the neovascularization.
