Trial 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… Read more about this study

About this study

Official title: Retinal Vascular Manifestations in Patients With Common Internal Diseases on Optical Coherence Tomography Angiography

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.

Read the 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.

Questions about this trial

What is this clinical trial studying?

An observational study of Hypertension and Diabetes Mellitus, run by Beijing Tongren Hospital at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 25 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Yu He, MD (+861058268320, bluelight323@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Vascular density of the retina (time frame: up to 5 years of follow-up.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05644548, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Sep 2025.
