A significant difference in clinical attachment loss and periodontal inflamed surface area among non-proliferative, proliferative and no diabetic retinopathy. Group 1: Nonproliferative diabetic retinopathy; Group 2: Proliferative diabetic retinopathy; Group 3: Type 2 diabetes without retinopathy. CAL: Clinical attachment loss; PISA: Periodontal inflamed surface area.
