Glaucoma is the second most leading cause of preventable blindness according to WHO statistics. It is found that the prevalence of Glaucoma is 3% in people above 40 years and it is 10% above 70 years of age [1]. Glaucoma results in damage to the cells in optic nerve called retinal ganglion cells [RGCs] leading to loss of vision and irretrievable blindness. Elevated Intra Ocular Pressure damages the retinal ganglion cells. Multiple factors such as family history, diabetes, obesity, stress, hypertension, high myopia has a positive association with Glaucoma [2].

Tratak kriya

According to Yogic principles of Ayurveda, the ancient Indian science of health, the helps in in upholding ocular health. Tratak kriya is a meditation technique that encompasses staring at a single point without blinking until tears begin to flow. Yogic literatures claim that the Tratak kriya was found to be effective in treatment of many eye diseases [2]. The staring continuously at a small object such as the candle flame that is placed at a few feet away from eyes or a distant object grounds to alternate relaxation and contraction of ciliary muscles of eye. In glaucoma patients, this effect results in improved outflow of aqueous humor reducing the intra Ocular Pressure


Acute coronary syndrome (ACS) is a condition characterized by symptoms and clinical manifestations associated with acute myocardial ischemia. According to 2012 data of the World Health Organization (WHO), the top three causes of death in the world are Ischemic Heart Disease with 7.4 million people, Stroke with 6.7 million people and Chronic Obstructive Pulmonary Disease (COPD with 3.1 people) ). AKS is the most common one among Ischemic Heart Diseases [7]. Acute Coronary Syndrome occurs as a result of impaired integrity of the atherosclerotic plaque in the coronary vessel [8]. The clot formed on the plaque disrupts coronary blood flow to various degrees. In addition to the clot, different degrees of coronary spasm may accompany the picture [9]. As a result of these changes, acute elevation myocardial infarction (STEMI), ST elevation acute myocardial infarction (NSTEMI) or unstable angina pectoris (Unstable Angina Pectoris, UAP) may occur in the clinic [10]. Patients with ischemic complaints may or may not have ST segment elevation in Electrocardiography (ECG). STEMI may be in patients with ST segment elevation and UAP or NSTEMI in patients without ST segment elevation. The distinction between these two conditions can only be made with cardiac enzymes. If there is an increase in cardiac enzymes, NSTEMI is UAP if there is no increase [11].
