Evaluation on Visual Outcome of TMS

The goal of this clinical trial is to learn if transcranial magnetic stimulation (TMS) can improve the visual outcomes in patients with visual impairment. The main question it aims to answer is:

• Does TMS improve the visual outcome in patients who suffer from visual impairment? Researchers will compare TMS to the control group who will not receive effective TMS treatment) to see if TMS works to improve the visual outcomes of the patients.

Participants will

* Undergo TMS treatment or no effective TMS for consecutive 5 days. * Visit the clinic once every 2 weeks for checkups and tests.

Treatment and study plan

TMS

Procedure

TMS treatment in this study indicates a non-invasive procedure called transcranial magnetic simulation (TMS) on visual cortex. The treatment intensity is set as 80% of the threshold of each participant. The treatment will be conducted every day for consecutive 5 days.

Control

Procedure

The control group will be given conventional consecutive care.

Primary outcomes

  1. Visual acuity

    Time frame: From enrollment to the end of treatment at 6 months

Secondary outcomes

  1. Visual field

    Time frame: From enrollment to the end of treatment at 6 months

Other outcomes

  1. Visual quality

    Time frame: From enrollment to the end of treatment at 6 months

    Visual function questionnaire score measured by VF-14 or VFQ-25

  2. Contrast sensitivity

    Time frame: From enrollment to the end of treatment at 6 months

    contrast sensitivity function

  3. Retinal sensitivity

    Time frame: From enrollment to the end of treatment at 6 months

    retinal sensitivity measured by perimetry
