Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Other | Change in Tear Cytokine Level | Change in levels of tear cytokines (mainly in inflammation cytokines, such as iL-17, TNF-alpha, etc.,). Change is the values from 8 and 12 weeks minus the the score at baseline visit. | 12 weeks | |
Other | Change in Lid Margin Abnormalities | Lid margin abnormalities were scored from 0 to 4 Change in lid margin abnormalities is the score from 4, 8 and 12 weeks minus the score at baseline visit. | 12 weeks | |
Other | Change in Meibum Quality | To evaluate meibum quality,five glands of the central part of the upper lid were assessed on a scale of 0-3 for each gland (total score range, 0-15).Change is the total score from 4, 8 and 12 weeks minus the score at baseline visit. | 12 weeks | |
Other | Change in Meibomian Gland Expressibility | The score of meibomian gland expressibility is range from 0-3. Change is the total score from 4, 8 and 12 weeks minus the score at baseline visit. | 12 weeks | |
Other | Change in Tear Film Break up Time, in Seconds (fluorescein staining) | Tear film break up time from1, 2, 4, 6, 8, 10 and 12 weeks minus values from baseline visit. | 12 weeks | |
Other | Change in Meibomian gland structure by Keratography | Change in Meibomian gland structure measured using the keratography machine. Change is the score from 8 and 12 weeks minus the values at baseline visit | 12 weeks | |
Primary | Change of Ocular Surface Disease Index (OSDI) Score | OSDI scores from 1, 2, 4, 6, 8, 10 and 12 weeks minus values from baseline. OSDI scores range from 0 to 100, score 0 indicating no ocular discomfort and higher scores indicating greater symptom severity. The minimal clinically significant change is 10 points. | 12 weeks | |
Secondary | Proportion of Participants with 10 Points or More Decreased in OSDI | Proportion of participants with at least 10 points decreased from baseline in Ocular Surface Disease Index (OSDI). | 12 weeks | |
Secondary | Change from Baseline in Lipid layer thickness (LLT) | LLT from 1, 2, 4, 6, 8, 10 and 12 weeks minus values from baseline among eyes that qualified for the study. The interferometer LLT measurement is a non-invasively and objectively method that produces numeric value. The range of the value is 0-100+; lower value indicates thinner lipid layer. | 12 weeks | |
Secondary | Change in Non-invasive Tear film breakup time (NI-BUT) | In this measurement, NI-BUT is measured using the keratography machine. NI-BUT is recorded as the number of seconds that elapse between the last blink and the appearance of the first dry spot in the tear film. Change is record as the values at 1, 2, 4, 6, 8, 10 and 12 weeks minus values at baseline visit. Possible range of score is 0->20. Lower values indicate greater severity. | 12 weeks | |
Secondary | Change in Tear Meniscus Height (TMH) by Keratography | Assessment of the tear film meniscus is a quantitative measurement of tear film quantity. In this measurement, TMH is measured using the keratography machine. Change is the values at 1, 2, 4, 6, 8, 10 and 12 weeks minus values at baseline visit. | 12 weeks | |
Secondary | Change in Corneal Fluorescein Staining Score | Corneal Flourescein Staining Score from 1, 2, 4, 6, 8, 10 and 12 weeks minus values from baseline visit among eyes that quality that qualified for the study. Possible range of scores is 0-15; higher scores indicate more severe. | 12 weeks | |
Secondary | Change in Self-Rating Anxiety Scale (SAS) | Medical Outcomes from study 20-Item Self-Rating Anxiety Scale. This scale range is 0-100 with lower scores indicating better self-reported mental health. Change is the score at 4, 8 and 12 weeks minus the score at baseline visit. | 12 weeks | |
Secondary | Change in Self-Rating Depression Scale (SDS) | Medical Outcomes from study 20--Item Self-Rating Depression Scale. This scale range is 0-100 with lower scores indicating better self-reported mental health. Change is the score at 4, 8 and 12 weeks minus the score at baseline visit. | 12 weeks | |
Secondary | Change in Subjective Happiness Scale | A 4-item scale designed to measure subjective happiness. Each of item is completed by choosing one of 7 options that finish a given sentence fragment. Change is the score at 4, 8 and 12 weeks minus the score at baseline visit. | 12 weeks | |
Secondary | Change in Pittsburgh Sleep Quality Index (PSQI) | Change is the score at 4, 8 and 12 weeks minus the score at the baseline visits. Scores for each question range from 0 to 3, and the total PSQI scores range from 0 to 100. | 12 weeks | |
Secondary | Change in SF-36 Physical Health Subscale | Medical Outcomes from study 36-Item Short Form Health Survey (SF-36) Physical Health Subscale. Subscale range is 0-100, with higher scores indicating better self-reported physical health-related quality of life. Change is the score at 4, 8 and 12 weeks minus the score at baseline visit. | 12 weeks | |
Secondary | Change in SF-36 Mental Health Subscale | Medical Outcomes from study 36-Item Short Form Health Survey (SF-36) Mental Health Subscale. Change is the score at 4, 8 and 12 weeks minus the score at baseline visit. | 12 weeks |
