Have you ever wondered if taking vitamins could improve your eye health? What about your vision? Or are eye vitamins a hoax, just like carrots decrease the risk of needing glasses for poor vision? Here are a few truths about eye vitamins and the effect they can have on vision and the prevention of disease.
One of the most common facial features that reveal the passage of time is the development of something known as tear troughs. Tear troughs are depressions that form beneath the eyes and cast a shadow that can make an individual appear tired, aged, or even unhealthy.
While the formation of tear troughs is usually not a significant health issue, their initial appearance can be unsettling. Considering this, it’s important to understand the causes of tear troughs, how they affect an individual’s appearance and self-esteem, and various treatment options that are available to address this concern.

Optic neuritis is an ocular sign of central nervous system (CNS) inflammation. The CNS is composed of the brain and spinal cord.
Specifically, optic neuritis is inflammation of the optic nerve. Inflammation is the process in the body where white blood vessels and chemical messengers are sent to an area of the body to initiate the healing process or to attack a foreign body. The optic nerve can become inflamed due to autoimmunity, infection, granulomatous diseases, tumor disorders, and demyelination.
The CNS system sends signals from the brain to the other parts of the body through nerves. Nerves tell the parts of the body what to do. Myelin is an insulation that wraps around the axon part of the nerve to speed nerve activity and signal conduction. Myelin is produced by a type of CNS cell called an oligodendrocyte. Attacks of demyelination can occur in parts of the brain, the spinal cord, and the optic nerve.
Alzheimer’s disease (AD) is the most common cause of dementia, an acquired progressive brain disorder. Currently, it is estimated that 44 million worldwide live with dementia, but the number is expected to triple by 2050 with an aging population. Memory loss and cognitive impairment from Alzheimer’s can interfere with one’s daily living.
Alzheimer’s disease is thought to be caused by an abnormal buildup of proteins in the brain. The initial damage occurs in the entorhinal cortex and hippocampus parts of the brain which are involved in memory.
Later into the disease process, the cerebral cortex becomes affected, which is responsible for language, reasoning, and social behavior. Eventually, other parts of the brain become damaged. Patients may have trouble finding the right words, have vision/spatial issues, and impaired reasoning or judgment in the early stages of the disease. As the disease progresses, those with AD may also have changes in their behavior or personality.
AD patients develop abnormal protein clumps (amyloid plaques) and tangled bundles of fibers (Tau) in the brain. Another finding in Alzheimer’s disease is the loss of connections between nerve cells (neurons) in the brain. Neurons transmit messages between parts of the brain, and from the brain to other parts of the body.
