About this study

Blepharospasm (BSP) is a chronic, idiopathic, recurrent and progressive disease, which mostly occurs in both eyes. It is mainly manifested as involuntary spasm of muscles around the eyes, leading to uncontrollable narrowing or even closure of blepharospasm. Although there is no pain in BSP patients, it can cause social or psychological dysfunction, make patients feel difficult in driving, reading and working, and seriously affect the social, work and life of patients.

Depression and anxiety are common and harmful mental disorders. At present, less than 40% of patients with depression can get effective treatment. Using simple and effective screening tools can effectively improve the detection rate of depression, so that patients can get timely and effective treatment. It is also an effective measure to prevent suicide.

Botulinum toxin type A (BTX-A) has achieved gratifying results in the treatment of dyskinesia. It has been confirmed that BTX-A has a significant effect on BSP. The effective rate is 70% - 90%. About 50% of the patients can regain normal or near normal visual function. At present, no prospective studies have explored this association between blepharospasm and depression / anxiety, and whether BTX-A can improve this mood disorder. Therefore, our research goal is to further study the relationship between blepharospasm and depression / anxiety, sleep in a prospective way, and to determine whether BTX-A treatment will affect depression / anxiety symptoms, so as to provide more theoretical basis for clinical treatment.

What is being measured

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

  1. Change from baseline blepharospasm evaluation at 3 months

    Patients will evaluated the Jankovic Rating scale (JRS),the total score of JRS is 8, and a change of 2 points in the JRS is clinically meaningful.

    Measured: Through study completion, 3 months.

Secondary outcomes (2)
  1. Change from baseline depression evaluation at 3 months

    Patients will evaluated the personal Health Questionnaire Depression Scale (PHQ-8) with a total score of 24, cut-points of 5, 10, and 15 represent mild, moderate, and severe levels of depressive symptoms.

    Measured: Through study completion, 3 months.

  2. Change from baseline anxiety evaluation at 3 months

    Patients will evaluated the Generalized Anxiety Disorder 7-item scale (GAD-7) questionnaires with a total score of 21, cut-points of 5, 10, and 15 represent mild, moderate, and severe levels of anxiety symptoms.

    Measured: Through study completion, 3 months.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

What does the primary outcome measure?

Change from baseline blepharospasm evaluation at 3 months (time frame: Through study completion, 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?
