Eatching & tearing of Eyes (Epiphora)

Definition:

Watery eyes (epiphora) tear persistently or excessively.

Depending on the cause, watery eyes may clear up on their own. Self-care measures at home can help treat watery eyes, particularly if caused by inflammation or dry eyes.

Causes:
Watery eyes can be due to many factors and conditions.

In infants, persistent watery eyes, often with some matter, are commonly the result of blocked tear ducts. The tear ducts don’t produce tears, but rather carry away tears, similar to how a storm drain carries away rainwater. Tears normally drain into your nose through tiny openings (puncta) in the inner part of the lids near the nose. In babies, the tear duct may not be fully open and functioning for the first several months of life.

In older adults, persistent watery eyes may occur as the aging skin of the eyelids sags away from the eyeball, allowing tears to accumulate and flow out.

Sometimes, excess tear production may cause watery eyes as well.

Allergies or viral infections (conjunctivitis), as well as any kind of inflammation, may cause watery eyes for a few days or so.

There may be some more other cause like due to different medication & other  diseases.

Do your eyes itch after you’ve been near a cat? Do they puff up or run with tears when pollen is in the air? Allergies of the eye affect about 20% of Americans each year, and are on the rise. The same inhaled airborne allergens — pollens, animal dander, dust mite feces, and mold — that trigger allergic rhinitis (the familiar sneezing, runny nose, and congestion) can lead to allergic conjunctivitis (inflammation of the conjunctiva, the lining of the eye). It’s not surprising that people with allergic rhinitis often suffer from allergic conjunctivitis as well.

About 50% of allergic conjunctivitis sufferers, who tend to be young adults, have other allergic diseases or a family history of allergies. About 80% of eye allergies are seasonal; the rest are perennial (year-round). The symptoms are itchy and red eyes, tearing, edema (swelling) of the conjunctiva or eyelid, and a mucous discharge. Although it can be uncomfortable, you can rest assured that it is not a threat to your vision.

Diagnosing allergic conjunctivitis:

Allergic conjunctivitis usually can be confirmed by your doctor based on your symptoms. Testing is not usually needed to diagnose the condition, but skin testing (the same kind that’s done for other allergic reactions) may help identify the allergens causing your symptoms.

If your symptoms don’t quickly respond to treatment, see your doctor in case you have a different condition. Dry eye, in particular, can mimic the symptoms of allergic conjunctivitis.

Treating allergic conjunctivitis:-

Avoidance is your first line of defense. If you are allergic to cats, for example, avoid them (or at least don’t touch your eyes when near one), and wash your hands immediately after touching one. If pollen is your nemesis, keep your windows closed and an air purifier or air conditioner going in pollen season. Also, don’t rub your eyes, because rubbing causes cells in the conjunctiva to release histamine and other inflammatory chemicals, which worsens symptoms. Use artificial tears (available without prescription) frequently for relief and to dilute allergens in the eye.

If your only allergy problem is allergic conjunctivitis, then medicated eye drops would be your first step. You can start with an over-the-counter product, such as ketotifen eye drops (Zaditor, Alaway). The active ingredient is an antihistamine and a mast cell stabilizer, both of which can control the immune system overreaction that leads to your symptoms. Prescription-strength products that have similar actions are also available.

Allergic conjunctivitis can also be treated with over-the-counter oral antihistamines such as loratadine (Claritin), cetirizine (Zyrtec), and fexofenadine (Allegra), or the prescription antihistamines desloratadine (Clarinex) and levocetirizine (Xyzal). These are especially useful for people that have other allergy symptoms in addition to conjunctivitis.

For allergic conjunctivitis that is very severe and doesn’t improve with other medications, there are prescription eye drops that contain corticosteroids, such as loteprednol etabonate (Alrex, Lotemax) and fluorometholone (Fluor-Op, FML Forte). However, these eye medications should only be used under the guidance of an ophthalmologist.

General  precautions  & Alternative treatment of eatching & tearing eyes:

*Remember to keep their eyes free from dust and other particles that cause a blocking of the tear ducts.

*Wash the face and eyes frequently as this will also help to keep you refreshed. Washing your eyes frequently also removes the impurities from around the area of the tear ducts, keeping them free from blockages.

*You could also keep your eyes moist with the use of some mild eye drops. This will help in reducing the itchiness and the dryness that you experience.

*If you are going outdoors, make sure to wear some protective eye wear that help to keep impurities out of the eyes, thereby avoiding any irritability of the sense organs.

*Rose water is an excellent remedy to soothe dryness or burning sensations that are experienced in the eyes. Washing out the eyes in a capful of rose water will provide instantaneous relief.

*There are occasions where the optical nerve of the eyes and the muscles around the eyes have been strained, leading to dryness and itching, followed by a continuous flow of secretions. In order to relax the eyes and the relevant muscles, place slices of cucumber over the eyelids while you rest your eyes. The cooling effect of the cucumber slices will provide a great deal of relief to your tired eyes.

*On certain occasions, a warm compress, made by dipping a piece of towel into warm water and pressing it gently over the eyes will provide relief from symptoms of itching and continuous flow of tears.

Fructose Worse Than Glucose for Human Health

While too much sugar is bad for health, scientists have found that over-consumption fructose is more dangerous than that of glucose.

Peter Havel and colleagues, at the University of California at Davis, Davis, conducted the 10-week study.

It was found that human consumption of fructose-sweetened but not glucose-sweetened beverages could adversely affect both sensitivity to the hormone insulin and how the body handles fats, creating medical conditions that increase susceptibility to heart attack and stroke.

In the study, overweight and obese individuals consumed glucose or fructose-sweetened beverages that provided 25% their energy requirements for 10 weeks.

During this period, individuals in both groups put on about the same amount of weight, but only those consuming fructose-sweetened beverages exhibited an increase in intra-abdominal fat.

In addition, only these individuals became less sensitive to the hormone insulin (which controls glucose levels in the blood) and showed signs of dyslipidemia (increased levels of fat-soluble molecules known as lipids in the blood).

The researcher said that although these are signs of the metabolic syndrome, which increases an individual’s risk of heart attack, the long-term affects of fructose over-consumption on susceptibility to heart attack remain unknown.

Researchers Make Synthetic HDL Cholesterol

US researchers have developed a synthetic form of good cholesterol known as HDL they hope will be able to keep levels of bad cholesterol  in check. The compound, which has a tiny core of gold, is manufactured using nanotechnology, and its developers think it has the potential to rid the body of excess bad cholesterol.

lipoprotein (HDL) particles like the one depicted here nevertheless incorporate large proteins that are difficult to mimic artificially.This is required  to  treat atherosclerosis.

.
“The idea is you take this and effectively just urinate it out,” said Chad Mirkin of Northwestern University in Chicago. Mirkin, director of Northwestern’s International Institute for Nanotechnology said, “The molecule mirrors the size and structure of high-density lipoprotein, or HDL. It is comprised of a carefully sized gold particle swathed in fat molecules known as lipids and capped off with a protein layer.”

It is designed to attract and trap low-density lipoprotein, or LDL, the bad kind of cholesterol that can build up in arteries and cause heart attacks and strokes. Powerful drugs known as statins can help lower LDL levels, but they do little to raise levels of protective HDL cholesterol.

“The hope is this will be a material that doesn’t have side effects, that allows you to do what the statins don’t do. That is raise the HDL level, which might be able reverse a lot of the damage and plaques that are already there,” Mirkin said.

Current drugs that raise natural levels of HDL, such as niacin, cause unpleasant side effects such as flushing. And while many drug companies are working to develop better HDL-raising drugs, few have succeeded. “HDL is a natural nanoparticle, and we’ve successfully mimicked it,” Mirkin said.

Gold is an ideal scaffolding material because its shape can be easily tailored, and it is non-toxic, making it a good drug candidate. Mirkin said “Gold is already used in therapies for arthritis and as contrast agent in imaging.”

Mirkin is testing the synthetic HDL molecules in animals. “Will they bind to cholesterol and effectively lower cholesterol, and will they reverse the damage of plaques? That would be absolutely spectacular,” he said. Analysts believe the market potential for HDL-raising drugs is well over $10 billion.

Current HDL-raising drugs include Abbott Laboratories Inc’s Niaspan, which also lowers a type of blood fat called triglycerides. In Europe, Merck & Co markets a drug called Tredaptive that combines niacin with an anti-flushing agent. Merck is already well into development of an HDL-raising drug called anacetrapib and plans to start late-stage trials in humans this year. The drug, also called MK-859, has a similar mechanism of action to a failed compound by Pfizer Inc called torcetrapib that was linked with deaths .
