Central retinal vein occlusion, also called CRVO, affects around 60,000 people in the United States each year, Weiss Eye Research Foundation reports. CRVO occurs when blood flow in the central retinal vein becomes blocked, forcing blood and fluid...
According to the U.S. Centers for Disease Control and Prevention, although approximately 61 million adults are considered to be at risk of losing their vision, only half of them have seen an eye doctor within the past year. Most people know that...
An ocular stroke is a blockage or reduction of blood supply to a vein or artery of the eye or the rupture of a vein or artery in the eye. The former is also known as an ischemic ocular stroke and the latter as an eye hemorrhage. When the eye's...
The carotid artery carries blood from the heart to the head and brain. There are two carotid arteries, one on each side of the neck. Over time, carotid arteries can become clogged with plaque as a result of coronary artery disease. Blockage of the...
High blood pressure or hypertension can cause damage to many organs and areas of the body including the eye--especially if the pressure is poorly controlled. Hypertension damages blood vessels by thickening their ways and impacting the amount of...
Veins in the retina often become blocked, or occluded. Occlusions can develop in the central retinal vein, located at the optic nerve, or in the branch veins, which drain blood from the retina. Branch vein occlusions, the most common type of...
High blood pressure, medically known as hypertension, affects all the blood vessels in the body, including those found in the eye. Blood vessel changes often lead to hemorrhage, or blood leakage, inside the eye, which is not visible from the...
Pulmonary tuberculosis (PTB) is a contagious infection that primarily affects the lungs. It is caused by the bacteria Mycobacterium tuberculosis. While pulmonary tuberculosis is curable, it can lead to serious complications in certain...
Licorice root is approximately 50 times sweeter than sugar. For thousands of years, licorice has been used in food and medicine and is Generally Recognized as Safe (GRAS) by the Food and Drug Administration (FDA). Glycyrrhizin and isoflavones are...
Arterial blockage is an umbrella term for a host of blockages that can occur in various arteries in the body. Blockages in the legs, in the eyes (central retinal arteries) and in the heart (coronary arteries) are all serious and can lead to a...
Diabetes is a systemic disease characterized by increased blood sugar, also known as hyperglycemia. It causes damage to many of the body's organs including the eye. Effects increase with age as the damage accumulates. According to a February 2008...

Inverted yoga postures such as the adho mukha vrksasana or handstand pose, offer significant benefits to the circulatory system as they encourage venous return, the return of deoxygenated blood to the heart. However, handstand may pose risks to...
The macula is the part of the retina with photoreceptor cells called cones, enabling visual acuity. According to Mitchell Scheiman, Maxine Scheiman and Stephen G. Whittaker authors of “Low Vision Rehabilitation,” the condition called...
Blood vessels in the eye provide oxygen and nutrients to the cells. When the eyes become red, it is commonly due to tiny blood vessels beneath the eyes bursting. Diseases such as diabetic retinopathy and macular degeneration cause the...
Swelling of the optic nerve can be caused by increased pressure inside the head. This type of swelling caused by increased pressure is called papilledema, and when found during an eye examination, an immediate search for the cause is necessitated....
The eye is a sensory organ that detects light and is one of the most complex of structures within the human body. The eye functions similar to that of a camera. Just as light passes through a lens, which is then focused at the back of the camera,...
The carotid arteries, one on each side of the neck, carry blood to the brain. Like other arteries, the carotid arteries can become blocked with plaque, a condition called atherosclerosis. A blockage can narrow the blood vessel, reducing blood flow...
