Objectives: To investigate patients with Proliferative Diabetic Retinopathy (PDR) using ultra-wide field fluorescein angiography (UWFA) images and to compare the detection rate of PDR progression using conventional seven standard field angiography (7SF) images. Methods: One hundred and one eyes of 67 patients with PDR who underwent fluorescein angiography using the Optos Optomap Panoramic 200A imaging system were included. Three hundred three images of 101 eyes at different time points (initial, Post-Panretinal Photocoagulation [PRP], and follow-up) were evaluated. In comparing 101 follow-up with 101 post-PRP images, we found newly developed Neovascularization (NNV) and newly developed non-perfusion (NNP) areas, which were then analyzed using two different methodologies: UWFA and 7SF. NNVs were counted while NNP area was measured in pixels using Image.. View More»
