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.

SUMAC

Botanical Name: Rhus coriaria
Family:    Anacardiaceae
Subfamily:Anacardioideae
Kingdom:Plantae
Order:Sapindales

Common Names: Sumac.

Arabic:Summaaq, Summaq
English:    Shumac, Sicilian sumac
Farsi:Somagh
French:    Sumac
German:    Sumach, Gewürzsumach, Färberbaum, Gerbersumach, Essigbaum
Nepali:Bhakmilo, Amilo (Rh. chinensis)
Turkish:Sumak, Somak

Habitat : Sumac is native to Middle East and Mediterian countries.It grows several places in the Euperian Continent.

Description:
Sumacs are shrubs and small trees that can reach a height of 1–10 m (3.3–32.8 ft). The leaves are spirally arranged; they are usually pinnately compound, though some species have trifoliate or simple leaves. The flowers are in dense panicles or spikes 5–30 cm (2.0–11.8 in) long, each flower very small, greenish, creamy white or red, with five petals. The fruits form dense clusters of reddish drupes called sumac bobs. The dried drupes of some species are ground to produce a tangy crimson spice.

Propagation: Sumacs propagate both by seed (spread by birds and other animals through their droppings), and by new shoots from rhizomes, forming large clonal colonies.

Edible Uses:
The fruits (drupes) of the genus Rhus are ground into a reddish-purple powder used as a spice in Middle Eastern cuisine to add a lemony taste to salads or meat. In Arab cuisine, it is used as a garnish on meze dishes such as hummus and is added to salads in the Levant. In Iranian (Persian and Kurdish) cuisines, sumac is added to rice or kebab. In Jordanian and Turkish cuisines, it is added to salad-servings of kebab and lahmacun. Rhus coriaria is used in the spice mixture za’atar.

In North America, the smooth sumac (R. glabra) and the staghorn sumac (R. typhina) are sometimes used to make a beverage termed “sumac-ade”, “Indian lemonade”, or “rhus juice”. This drink is made by soaking the drupes in cool water, rubbing them to extract the essence, straining the liquid through a cotton cloth, and sweetening it. Native Americans also use the leaves and drupes of the smooth and staghorn sumacs combined with tobacco in traditional smoking mixtures.

Sumac is a very popular condi­ment in Turkey and Iran, where the ground fruits are liberally sprinkled over rice. Mixed with freshly cut onions, it is fre­quently eaten as an appetizer. The well-known Turkish fast food specialty döner kebap is sometimes flavoured with sumac powder.

In Jordan, a spice mixture called zahtar  is extremely popular; it took its name from a local species of marjoram which is one of its main ingredients. Since this West Asian marjoram is hardly available outside of the region, it must be substituted by a mixture of marjoram with some thyme or oregano. Zahtar is, then, made by combining the dried marjoram herb with nutty sesame seeds, acidic sumac, salt and optionally some pepper. Similar mixtures are reported from Syria and Israel. Zahtar is mostly used to spice up fried and barbecued meat up to taste; combined with olive oil, it can also be used as a bread dip like the closely related Egypt spice mixture dukka.

Another use of sumac is recorded from Lebanon, Syria and Egypt: The fruits are cooked with water to a thick, very sour essence, which is, then, added to meat and vegetable dishes; this method was also common as early as in Roman times (see silphion for details of Roman cookery) and finds a close parallel in the usage of tamarind in contemporary Indian and Indonesian cuisines.

Outside of the Middle East, the true sumac spice is not known; yet, there are sumac species with culinary merit also further in the East. For example, Rh. chinensis (Chinese Sumac) grows in the Himalayas, in China and South East Asia. In Nepal, it is used to prepare a delicious sour and fruity pickle (amilo achar by some Himalayan ethnicities like the Thakali. In the North East Indian states Nagaland and Mizoram, sumac fruits are dried, coarsely ground and used as table condiment, or (often mixed with salt and chile powder) just enjoyed between meals.

Medicinal Uses:
It is said to have diuretic and antipyretic properties.Sumac was used as a treatment for half a dozen different ailments in medieval medicine, primarily in Middle-Eastern countries (where sumac was more readily available than in Europe). An 11th-century shipwreck off the coast of Rhodes, excavated by archeologists in the 1970s, contained commercial quantities of sumac drupes. These could have been intended for use as medicine, as a culinary spice, or as a dye. Staghorn sumac is a powerful antioxidant.Medical uses have included digestion and bowel problems.

Other Uses:
Dye and tanning agent:
The leaves of certain sumacs yield tannin (mostly pyrogallol-type), a substance used in vegetable tanning. Notable sources include the leaves of R. coriaria, Chinese gall on R. chinensis, and wood and roots of R. pentaphylla. Leather tanned with sumac is flexible, light in weight, and light in color. One type of leather made with sumac tannins is morocco leather.

Some beekeepers use dried sumac bobs as a source of fuel for their smokers.

Sumac stems also have a soft pith in the center that is useful in traditional native American pipemaking. They were commonly used as pipe stems in the northern United States.

Known Hazards: Some species formerly recognized in Rhus, such as poison ivy (Toxicodendron radicans, syn.Rhus toxicodendron), poison oak (Toxicodendron diversilobum, syn. Rhus diversiloba) and poison sumac (Toxicodendron vernix, syn. Rhus vernix), have the allergen urushiol and can cause severe allergic reactions. Poison sumac may be identified by its white drupes, which are quite different from the red drupes of true Rhus species.

Mowing of sumac is not a good control measure, since the wood is springy, resulting in jagged, sharp-pointed stumps when mowed. The plant will quickly recover with new growth after mowing. Goats have long been considered an efficient and quick removal method, as they eat the bark, which helps prevent new shoots.
