Demonstration Clinical Study of Dry Eye Disease Advantage

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.

Referring to the Chinese Expert Consensus on Dry Eye: Treatment (2020), this course of treatment totaled 6 weeks.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Chinese Medical Evidence Scale
Time Frame: 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.
From enrollment to end of 6-week treatment
Ocular Surface Disease Index
Time Frame: 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.
From enrollment to end of 6-week treatment
Fluorescein Breakup Time
Time Frame: From enrollment to end of 6-week treatment
Efficacy was evaluated by the values tested before and after the intervention
From enrollment to end of 6-week treatment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Schirmer Ⅰ test
Time Frame: From enrollment to end of 6-week treatment
Efficacy was evaluated by the values tested before and after the intervention
From enrollment to end of 6-week treatment
Height of the River of Tears
Time Frame: From enrollment to end of 6-week treatment
Efficacy was evaluated by the values tested before and after the intervention
From enrollment to end of 6-week treatment
fluorescent staining of the cornea
Time Frame: 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.
From enrollment to end of 6-week treatment
Classification of blepharoplasty deficiency
Time Frame: 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.
From enrollment to end of 6-week treatment
