Background Lifestyle modification is a newly recommended complementary treatment for dry eye (DE) disorder. Objective To investigate the effect of a 6-month high-intensity interval aerobic exercise (HIIAE) (conducted 30 min, 3 times weekly) alone or combined with a caloric-restriction approach, the Mediterranean diet (MD), on DE parameters in obese hypertensive elderly. The design, settings, participants, and intervention This is a randomized controlled trial included sixty obese hypertensive elderly with DE based on university-based hospital recruitment. Elderly were randomly assigned to the experimental group (n = 30 elderly received HIIAE plus MD) and control group (n = 30 elderly received only HIIAE). Besides anthropometry (abdominal circumference, body weight, and body mass index) and blood pressure (measured in systole and diastole), DE parameters (tear film break-up time, DE scoring system, ocular surface disability index questionnaire, Schirmer’s test, and Oxford grading system) were evaluated. Results Significant improvements in anthropometry, blood pressure, and DE parameters were higher in the experimental group than in the control group. Conclusion Aging-related DE symptoms and signs can be prevented and/or treated with HIIAE alone or combined with MD in obese hypertensive elderly with DE disorder.

Objectives Yoga is used as a complementary therapy to control the symptomatic and complicated consequences of type 2 diabetes mellitus (T2DM) but the effect of Jyoti-Trataka yoga (gazing steadily at a 4-feet away-fixed candle flame) on the intraocular pressure (IOP), autonomic control, and fasting blood glucose (FBG) in T2DM patients with high-tension primary open-angle glaucoma (POAG) was not previously investigated. This study aimed to search the effect of Jyoti-Trataka on IOP, systolic blood pressure (SBP), respiratory rate (RR), diastolic blood pressure (DBP), FBG, and pulse rate (PR) in T2DM patients with bilateral high-tension POAG. Methods The patients with a 52- to 67-year range and body mass index below 30 kg/m2 were randomly assigned to one of two 30-patient groups, study or control groups. Besides the administered oral hypoglycemic drugs by both groups, the study group only received one month of daily 55-min Jyoti-Trataka session. Results A significant decrease (p<0.05) was identified after the comparison between the pre and post SBP, RR, DBP, FBG, IOP of both eyes, and PR in the study group while the control group exhibited no significant changes of all measures (p>0.05). In-favor-of the study group, the between-group post-treatment comparison showed a significant improvement of all measures (p<0.05). Conclusions Jyoti-Trataka is a good yogic complementary therapy that can be used to regulate autonomic functions, blood glucose, and IOP in T2DM patients with high-tension POAG.
