Summary

Hypertension, diabetes mellitus, and dyslipidemia are common internal diseases, and all diseases are atherosclerosis risk factors. Previous studies applied color fundus photography to analyze retinal vascular changes (including exudation, hemorrhage, neovascularization, etc.) in patients with hypertension or diabetes, but the examination results could not be quantified. This study intends to apply optical coherence tomography angiography (OCTA) to examine retinal vessels. This method has the following advantages: 1) It can quantify vascular changes, and 2) It is noninvasive and reproducible for patients' follow-up. This study was designed to investigate retinal vascular changes in patients with hypertension, diabetes, and dyslipidemia on OCTA. We will collect the patients' general information (gender, age), comorbidities, medications, blood lipids, blood glucose, carotid ultrasound, ankle-brachial index, ambulatory blood pressure monitoring, color fundus photography, and OCTA results. We will follow up with the patients for five years and conduct the mentioned examinations once a year. We will also investigate the correlation between systemic atherosclerosis (such as coronary artery stenosis, and carotid artery stenosis) and retinal vasculopathy in patients with these diseases.

Detailed description

Patients with hypertension, diabetes mellitus, or dyslipidemia, who go to the department of geriatric medicine, Beijing Tongren Hospital from March 2022 to December 2023 will be included. We will collect general information, comorbidities, medication, laboratory tests, and examination results. These patients will be followed up for 5 years with a yearly collection of comorbidities, medication, laboratory tests, and examination results.
