The aim of this observational study is to investigate the relationship between periodontal disease severity and retinal layer thickness in patients diagnosed with diabetic retinopathy (DR), using optical coherence tomography (OCT) for assessment. The main question this study seeks to answer is: Do measurable changes in retinal layer thickness occur as periodontal disease severity increases in patients with diabetic retinopathy? Participants will include adult individuals with a confirmed clinical diagnosis of DR. Periodontal status will be assessed through standard clinical parameters, including plaque index, probing pocket depth, clinical attachment loss, and bleeding on probing. Retinal layer thickness will be measured using high-resolution OCT and OCT angiography (OCTA) devices. The study aims to analyze potential associations between periodontal disease severity and morphological as well as vascular changes in the retina.
