There are many different causes of the conditions collectively referred to as dry eye syndrome, including:

Blepharitis can often cause Dry Eye symptoms due to inflammation of the eye lid margins, which is caused by a bacterial infection (Staphylococci). This condition can compromise the quality of the tear film causing tears to evaporate more quickly. The bacteria produce waste material that can cause a mild toxic reaction leading to chronic red, irritated eyes. Click Blepharitis for treatment. LASIK surgery temporarily disrupts the ocular surface/lacrimal gland unit. See similar questions...

Dry eye is a catch-all term referring to abnormalities of the tear layer which normally coats the surfaces of the eyes, providing clear vision and protecting sensitive surface tissues. Other names for dry eye include dry eye syndrome, chronic dry eye, dry eye disease, and keratoconjunctivitis sicca. Dry eye does not mean your eyes are "dry" - in fact, many people who suffer from dry eye have chronically watery eyes. (Click here for more about dry eye symptoms. See similar questions...

No. Atropine eye drops are used to dilate the pupil during eye exams, and also to treat the conditions amblyopia, esotropia and strabismus. Children with DS seem to have a greater dilation in response to atropine, and the dilation appears to last longer as well. However, there is no evidence that atropine eye drops has any effect on the body beyond the eyes. (North RV, Ophthal Physiol Opt, 7(2): 109-114, 1987) See similar questions...

In PRK, because the laser removes tissue from the surface of the eye, the body will attempt to fill in the defect much like if you had a cut on your hand. Since corneal tissue has different healing properties, the process can normally be regulated with the use of topical steroid drops which patients may be required to use over a one-month period. In LASIK, these drops are only used for a week. These drops will rarely cause any problems. See similar questions...

Dry eye syndrome is a condition caused by loss of water from the tear film. When the tear film loses water the concentration of salts and proteins, relative to the amount of water, increases--the tear film concentration increases. When tear film concentration increases scientists say that its "osmolarity" increases. This increase in tear film osmolarity causes the characteristic irritation and changes on the eye surface known as dry eye syndrome. See similar questions...

Artificial tears have been the mainstay of dry eye treatment. Until recently, these used to be recommended like cigarette brands--doctors would hand out whatever they had in the sample closet, and patients would pick their brand. Patients would find that no matter how long or how frequently they used these drops their eyes would still be dry. Fortunately, Jeffrey Gilbard, MD, working at Harvard Medical School's Schepens Eye Research Institute, has developed an eye drop call TheraTears. See similar questions...

During reading and TV or computer viewing, the rate of eyelids blinking reduces significantly, especially in dryer climates. This causes the tear film to evaporate leading to dryness of the eyes. This may happen in some people, especially more when they are tired, or have spent long hours watching TV or computers. Computer Users tend to blink much less frequently (about 7 times per minute vs. a normal rate of around 22 times/minute). See similar questions...

Tulsee Eye Drops are formulated by using aqueous extracts of the 17 herbs. Each of these herbs are chosen for its beneficial properties and combined with Hypromellose, a well known Ophthalmic lubricant. The MHRA nor the US FDA has not evaluated the benefit of the herbs in Tulsee Eye Drops. Tulsee Eye Drops are not intended to diagnose, treat, cure or prevent disease.

Tulsee Eye Drops may be used as often as needed. It is wise to use the Tulsee Eye Drops at least twice each day. Instil two drops in each eye before starting work and repeat before going to bed. See similar questions...

Start all post–op drops as soon as you get home from surgery. PLEASE follow the written instructions provided upon discharge. See similar questions...

Jeffrey Gilbard, MD, conducting research sponsored by the National Eye Institute, has proven that dry eye is caused by any condition that increases tear film evaporation, or by any condition that decreases tear production. These conditions, in turn, may be caused by a dietary deficiency of omega-3 essential fatty acids. Evaporation can increase from chronic eye lid inflammation or "blepharitis," specifically posterior blepharitis or meibomitis. See similar questions...

Dry eye syndrome does not truly come and go, but in the early stages of the condition, or with mild dry eye, you may only have symptoms after long days, or with environmental conditions that decrease your blink rate (i.e. computer use) or under conditions that increase evaporation from your tear film (i.e. wind, dry air, etc.). Some patients may notice discomfort only when they wear their contact lenses. See similar questions...

Symptoms vary greatly. Some symptoms, such as watery eyes, are surprising. Some of the most common symptoms experienced by dry eye patients: See similar questions...

Treatments need to be tailored for the type of dry eye. While some treatments attempt to treat the source, with moderate to severe dry eye it is almost always necessary to use treatments and products which reduce the symptoms so that the life-impact is lessened. See similar questions...

While eye drops can give temporary relief from the symptoms of Dry Eye Syndrome, studies have shown that increased consumption of foods rich in Omega-3 acids can reduce various forms of eye inflammation (blepharitis, tear gland, etc.) that can cause Dry Eye Syndrome. These fatty acids are also used by the glands in the eyelid to create a healthy layer of oil in the tear film that help to keep the eye hydrated. See similar questions...

Drusen alone do not usually cause vision loss. In fact, scientists are unclear about the connection between drusen and AMD. They do know that an increase in the size or number of drusen raises a person's risk of developing either advanced dry AMD or wet AMD. These changes can cause serious vision loss.
