About this study

Official title: Effectiveness of TMS for Visual Restoration: a Multicenter Randomized Controlled Trial

The goal of this clinical trial is to learn if transcranial magnetic stimulation (TMS) works to restore vision in adults with severe retinal degeneration. It will also learn about the safety of TMS treatment. The main questions it aims to answer are:

  1. Does TMS treatment improve the visual function of participants?
  2. What medical problems do participants have when receiving TMS treatment? Researchers will compare TMS treatment to a sham stimulation (identical procedures using a sham coil without effective magnetic field output) to see if TMS treatment works to restore their vision.

Participants will:

UndergoTMS treatment to a sham stimulation for consecutive 5 days Visit the clinic at 5 days, 4 weeks, 3 months, 6 months, 12 months after start of the treatment for checkups and tests

Being tested
Transcranial magnetic stimulation targeting occipital visual cortex, Sham stimulation
Medical subject headings
Retinal Degeneration, Vision Disorders, Blindness

What is being measured

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

  1. Best-corrected visual acuity (BCVA) change

    the change of best-corrected visual acuity (BCVA, measured by internationally standard EDTRS chart) between 3 months after the end of treatment and baseline

    Measured: Baseline and 3 months

Secondary outcomes (1)
  1. Best-corrected visual acuity (BCVA) change

    the change of BCVA (EDTRS) between 12 months after treatment and baseline

    Measured: Baseline and 12 months

Questions about this trial

What is this clinical trial studying?

A study testing Transcranial magnetic stimulation targeting occipital visual cortex in people with Retinal Degeneration and Vision Impairment and Blindness, run by Shanghai High Myopia Study Group at 4 sites 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 3 inclusion and 7 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: opening soon, as of the sponsor's last update on 23 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites 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. Some participants in this study may receive a placebo. 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 Xiangjia Zhu, PhD, MD (+0086-02164377134, zhuxiangjia1982@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Best-corrected visual acuity (BCVA) change (time frame: Baseline and 3 months). 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 23 Feb 2026.
