Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Study population: The study population will consist of adult patients diagnosed with Graves' disease who are followed in the endocrinology and ophthalmology clinics of the participating institution. Patients who meet the inclusion criteria and have available optical coherence tomography (OCT) measurements and laboratory data will be included in the patient group. The control group will consist of age- and sex-matched healthy volunteers without a history of thyroid disease or ocular pathology, recruited from individuals undergoing routine ophthalmologic examination. All participants will be evaluated for neuroretinal structural parameters using OCT and systemic inflammatory markers obtained from laboratory tests.

Who may be able to join

  • Age ≥ 18 years
  • Diagnosis of Graves' disease (for the patient group)
  • No known thyroid disease in healthy control participants
  • Availability of optical coherence tomography (OCT) measurements and laboratory data
  • Time interval between OCT examination and blood sampling ≤ 10 days

Who cannot join

  • Presence of glaucoma, optic neuropathy, or retinal vascular diseases
  • Macular diseases, uveitis, or severe refractive error (high myopia >6 diopters)
  • Diabetic retinopathy
  • History of previous intraocular surgery
  • History of active infection, malignancy, or systemic inflammatory disease
  • Poor-quality OCT measurements (segmentation errors or low signal strength)

About this study

Official title: Relationship Between Systemic Inflammation, Thyroid Autoimmunity, and Neuroretinal Structures in Graves Disease

This retrospective observational study aims to evaluate the relationship between systemic inflammatory parameters, thyroid autoimmunity markers, and neuroretinal structures in patients with Graves disease. Medical records of patients diagnosed with Graves disease and healthy control subjects evaluated at Elazığ Fethi Sekin City Hospital between August 2018 and January 2026 will be reviewed. Optical coherence tomography (OCT) measurements, including macular thickness and peripapillary retinal nerve fiber layer (RNFL) thickness, will be analyzed. Laboratory parameters such as complete blood count-derived inflammatory indices, C-reactive protein, thyroid function tests, and thyroid autoantibodies will also be recorded. The study will compare neuroretinal parameters between healthy controls, Graves disease patients without ophthalmopathy, and Graves disease patients with ophthalmopathy, and will investigate potential associations between systemic inflammation, thyroid autoimmunity, and neuroretinal structural changes.

Study groups in NCT07480720
Study groupRoleWhat they receive
Healthy ControlsAge-matched healthy individuals without known thyroid disease or autoimmune disorders who underwent ophthalmologic examination and optical coherence tomography evaluation.
Graves Disease Without OphthalmopathyPatients diagnosed with Graves disease who do not have clinical signs of Graves ophthalmopathy and who underwent optical coherence tomography evaluation.
Graves Disease With OphthalmopathyPatients diagnosed with Graves disease who have clinical findings consistent with Graves ophthalmopathy and who underwent optical coherence tomography evaluation.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Peripapillary Retinal Nerve Fiber Layer Thickness

    Evaluation and comparison of peripapillary retinal nerve fiber layer thickness values in different quadrants among study groups.

    Measured: Retrospective evaluation of OCT measurements obtained between August 2018 and January 2026

  2. Macular Thickness Measured by Optical Coherence Tomography

    Comparison of macular thickness measurements among healthy controls, Graves disease patients without ophthalmopathy, and Graves disease patients with ophthalmopathy.

    Measured: Retrospective evaluation of OCT measurements obtained between August 2018 and January 2026

Questions about this trial

What is this clinical trial studying?

An observational study of Graves Disease and Graves Ophthalmopathy, run by Elazıg Fethi Sekin Sehir Hastanesi at 1 site in Turkey (Türkiye).

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 5 inclusion and 6 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 18 Mar 2026. 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 Turkey (Türkiye). 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 SİNEM KESER, MD (+905070646384, kesersinem@hotmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Peripapillary Retinal Nerve Fiber Layer Thickness (time frame: Retrospective evaluation of OCT measurements obtained between August 2018 and January 2026). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 18 Mar 2026.
