- Brief Summary
People staring at computer screens for long hours, blinking less frequently, or having long-term contact lens wear are prone to dry eye disease (DED). DED is a multifactorial disease accompanied by inflammation of the ocular surface. Further, DED may degrade vision and is associated with depression and have an adverse impact on patient's quality of life. Sudarshan Kriya Yoga (SKY) incorporates standardized collection of breathing techniques followed by Automatic Self Transcending Meditation (ASTM) may help reduce stress, depression, and anxiety, enhance quality of life in patients diagnosed with DED. Thus, the investigators will be studying the effect of SKY plus ASTM on quality of life of DED patients. The investigators plan to conduct a single-center pilot RCT. Patients with DED will be randomized to SKY followed by ASTM plus Usual care (UC) or UC alone to assess changes in health-related quality of life (HRQOL). HRQOL is a vital construct focusing on impact of health on quality of life. Along with HRQOL the investigators will measure changes in extent of depression and anxiety. Additionally, majority of current ophthalmic literature describes changes in clinical variables whilst lacking information on HRQOL. Thus, there is a high necessity to assess if there is an association between HRQOL and routinely measured clinical data. Through this study the investigators shall attempt to correlate HRQOL with clinical data.
- Detailed Description
Background: Prevalence of dry eye disease (DED) ranges from 3.5% to 33.7% and increase with age. Further, DED is associated with decreased productivity, absenteeism from work, depression, and has an adverse impact on patient's quality of life. Odds of a DED patient suffering from depression is 2.9 and anxiety is 2.8. Yoga - a practice to help improve health and well-being - has also been the subject of clinical studies globally. Two central aspects of yoga practice are physical postures and breathing exercises. These breathing exercises aim to focus the mind, facilitate relaxation and enhance wellness.
Evidence further suggests beneficial effects of a standardized collection of breathing techniques called Sudarshan Kriya Yoga (SKY) on individuals suffering from depression. SKY includes three-stage breathing with Victory breath (slow deep breathing that consists of 4 to 6 breaths per minute), Bellow's breath (forceful rapid deep breathing that consists of 20 to 30 breaths per minute), and a rhythmic breath technique. SKY followed by Automatic Self Transcending Meditation (ASTM) involves breathing exercise followed by meditation. ASTM utilizes a specific sound value mantra to draw attention inward and permit the mind to experience a restful but alert state of consciousness. It helps quiet the mind and induces physiological and mental relaxation whilst the eyes are shut. ASTM may help with depression, anxiety, stress, and may enhance quality of life. Thus, the investigators will be studying the effect of SKY plus ASTM on quality of life of DED patients. Key goal of proposed research is to evaluate HRQOL, depression, anxiety of patients with DED in SKY followed by ASTM and usual care (UC) versus UC alone from baseline to 24 weeks.
Primary Hypothesis: The investigators hypothesize that in patients with dry eye disease in SKY + ASTM + UC may lead to significant improvement in HRQoL compared to UC alone from baseline to 24 weeks.
Secondary Hypotheses: The investigators hypothesize that in patients with DED 1) HRQoL is associated with regularly measured clinical variables 2) SKY + ASTM + UC leads to significant improvement in depression and anxiety symptoms at 24 weeks compared to UC alone.

- Primary Outcome Measures
Name Time Method Change in Health Related Quality of Life (HRQoL) Up to 24 weeks Health Related Quality of LIfe (HRQoL) is an essential measure of quality of life related to health. HRQoL will be measured using time trade-off (TTO) questionnaire. HRQoL varies between 0 and 1 where the score of 1 represents perfect health and 0 represents death.
- Secondary Outcome Measures
Name Time Method Dry Eye Assessment Up to 24 weeks Standardized Patient Evaluation of Eye Dryness (SPEED) Questionnaire
Visual Function Score Up to 24 weeks Visual related quality of life measured using National Eye Institute Visual Function Questionnaire-25 (NEI VFQ-25). The most widely used instrument in vision-related functioning is the NEI VFQ-25. It was designed specifically for a clinical setting and consists of 12 domains: general health, general vision, visual pain, near activities, distance activities, social functioning, mental health, role difficulties, dependency, driving, colour vision and peripheral vision. The shorter 25-item version questionnaire is widely used in different groups of patients and shown to be internally consistent, reproducible and responsive in glaucoma patients. The NEI VFQ-25 scores have a closer relationship to clinical outcomes, in comparison to generic instruments. The scores range from 0 to 100 where higher score represents better vision related quality of life.
Depression Up to 24 weeks Center for Epidemiologic Studies Depression Scale (CES-D) will be used to measure depression. It is one of the most common validated tools used to measure depression in research to identify depressive symptoms. Additionally, it is a brief standardized valid tool for assessing depressive symptoms. Possible range of scores is zero to 60, with the higher scores indicating the presence of more depressive symptoms.
Canadian Dry Eye Assessment Up to 24 weeks Canadian Dry Eye Assessment
State and Trait Anxiety Up to 24 weeks State-Trait Anxiety Inventory (STAI)
Sleep Quality Up to 24 weeks Pittsburgh Sleep Quality Index (PSQI)
Community Integration Up to 24 weeks The community integration questionnaire (CIQ) was used to provide a quantitative indicator for the level of social support and ability to perform appropriate roles at home and within the community. The CIQ contains 15-items and uses behavioural items of integration to achieve better reliability. The total CIQ score ranges from 0 to 29, with a higher score representing a higher level of social support and complete community integration.
