Dry Eye Disease (DED)
Conditions
Brief summary
In this study, dry eye disease (leukoaraiosis) is used as a model disease, and the methodological system for evaluating the clinical efficacy of Chinese medicine for dry eye disease is constructed with the core of subgrouping dynamic and static parallel group design, so as to carry out a real-world demonstration study of dry eye disease as a dominant disease in Chinese medicine treatment. The purpose of this study is to demonstrate the selection of individualized clinical interventions and the superiority of dynamic diagnosis and treatment using dry eye as a disease model. The study provides a clinical example of a subgroup-based dynamic and static parallel group design for TCM clinical research on disease-based integrated treatment. Based on the conclusions of the efficacy evaluation study, investigators will provide real-world clinical data of dry eye syndrome for the artificial intelligence prediction of the integrated platform of individualized clinical evaluation and evidence support of Chinese medicine with multi-source data integration.
Interventions
COMBINATION_PRODUCTfumigation with Chinese medicine
Eye fumigation with the Eyesight Eye Therapy,10 minutes once daily for 6 weeks.
DRUGOral herbal medicine
Patients were identified into the appropriate group according to the individual evidence profile, and the herbal formula under the corresponding evidence profile was taken orally as one dose of 150 ml of water twice a day for 6 weeks.
DRUGModern Western Medicine
Referring to the Chinese Expert Consensus on Dry Eye: Treatment (2020), this course of treatment totaled 6 weeks.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Chinese Medical Evidence Scale | From enrollment to end of 6-week treatment | The TCM evidence scale converts symptoms and signs into TCM evidence, and assigns 1, 2, and 3 points according to three levels of severity, with reference to the Guiding Principles for Clinical Research on New Drugs of Traditional Chinese Medicine and the International TCM Clinical Practice Guidelines for Stemmed Eyes (2021-12-14). If the points of TCM evidence are higher or unchanged after the intervention, it means that the intervention measures are ineffective or inefficient, and that patients' clinical symptoms do not improve significantly or their conditions worsen after the treatment. If the TCM syndrome score increases or remains unchanged after the intervention compared with that before treatment, it means that the intervention is ineffective or inefficient, and the patient's clinical symptoms do not improve or worsen after treatment. |
| Ocular Surface Disease Index | From enrollment to end of 6-week treatment | By evaluating the points before and after the intervention treatment, if the points are lower than before the treatment, it suggests that the intervention treatment is effective, on the contrary, it indicates that the intervention is ineffective or ineffective, and the clinical symptoms of the patients do not improve significantly or worsen after the treatment. |
| Fluorescein Breakup Time | From enrollment to end of 6-week treatment | Efficacy was evaluated by the values tested before and after the intervention |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Schirmer Ⅰ test | From enrollment to end of 6-week treatment | Efficacy was evaluated by the values tested before and after the intervention |
| Classification of blepharoplasty deficiency | From enrollment to end of 6-week treatment | The efficacy was evaluated by scoring the blepharoplasty area values detected before and after the intervention. According to the Chinese Expert Consensus on Meibomian Gland Dysfunction (2023), investigators graded the results as follows: score 0: no meibomian gland deficiency; score 1: meibomian gland deficiency ratio <1/3; score 2: meibomian gland deficiency ratio 1/3-2/3; and score 3: meibomian gland deficiency ratio >2/3. |
| Height of the River of Tears | From enrollment to end of 6-week treatment | Efficacy was evaluated by the values tested before and after the intervention |
| fluorescent staining of the cornea | From enrollment to end of 6-week treatment | See the Chinese Expert Consensus on Dry Eye: Expert Consensus on Definition and Classification (2020): the cornea was divided into 4 quadrants on average, and each quadrant was scored from 0 to 3 according to the staining of sodium fluorescein, with a score of 0: no staining; 1: 1-30 punctate staining; 2: >30 punctate staining but staining not fused; and 3: fusion of the corneal punctate staining with the appearance of filaments and ulcers, etc. The final tally scores for each quadrant were summed. The efficacy was evaluated by tallying the scores detected before and after the intervention. |
