Persistent dryness, scratching and burning in your eyes are signs of dry eye syndrome. These symptoms alone may be enough for your eye doctor to diagnose dry eye syndrome. But sometimes he or she may want to measure the amount of tears in your eyes. A thin strip of filter paper placed at the edge of the eye, called a Schirmer test, is one way to measure.
Some people also experience a “foreign body sensation,” the feeling that something is in the eye. And it may seem odd, but sometimes watery eyes can result from dry eye syndrome, because the excessive dryness works to overstimulate production of the watery component of your eye’s tears.
Tears bathe the eye, washing out dust and debris and keeping the eye moist. They also contain enzymes that neutralize the microorganisms that colonize the eye. Tears are essential for good eye health. In dry eye syndrome, the eye doesn’t produce enough tears, or the tears have a chemical composition that causes them to evaporate too quickly.
Dry eye syndrome has several causes. It occurs as a part of the natural aging process, especially during menopause; as a side effect of many medications, such as antihistamines, antidepressants, certain blood pressure medicines, Parkinson’s medications and birth control pills; or because you live in a dry, dusty or windy climate. Another cause is insufficient blinking, such as when you’re staring at a computer screen all day.
Dry eyes are also a symptom of systemic diseases such as lupus, rheumatoid arthritis, rosacea or Sjogren’s syndrome (a triad of dry eyes, dry mouth and rheumatoid arthritis or lupus).
Long-term contact lens wear is another cause; in fact, dry eyes are the most common complaint among contact lens wearers. Recent research suggests that smoking, too, can increase your risk of dry eye syndrome. With increased popularity of eyelid surgery (blepharoplasty) for improved appearance, dry eye complaints now occasionally are associated with incomplete closure of eyelids following a procedure.
Treatment for Dry Eyes
Dry eye syndrome is an ongoing condition that may not be cured (depends on the cause), but the accompanying dryness, scratchiness and burning can be managed. Your eyecare practitioner may prescribe artificial tears, which are lubricating eyedrops that may alleviate the dry, scratching feeling.
Restasis eyedrops (cyclosporine in a castor oil base) go one step further: they help your eyes to increase tear production. Restasis treatment is the first of its kind.
If you wear contact lenses, be aware that many eye drops, especially artificial tears, cannot be used while your contacts are in your eyes. If your eye dryness is mild, then contact lens rewetting drops may be sufficient to make your eyes feel better, but the effect is usually only temporary.
If the problem is environmental, you should always wear sunglasses when outdoors, to reduce exposure to sun, wind and dust. Indoors, an air cleaner can filter out dust and other particles from the air, while a humidifier adds moisture to air that’s too dry because of air conditioning or heating.
Mild dehydration may make dry eye problems worse. This is especially true during hot, dry and windy weather. But the symptoms of dry eye syndrome may be improved by simply drinking more water.
If medications are the cause of dry eyes, discontinuing the drug generally resolves the problem. But in this case, the benefits of the drug must be weighed against the side effect of dry eyes.
Treating any underlying eyelid disease, such as blepharitis, helps as well. This may call for antibiotic or steroid drops plus frequent eyelid scrubs with an antibacterial shampoo.
If you are considering LASIK, be aware that dry eyes may disqualify you for the surgery, at least until the problem is resolved. Dry eyes increase your risk for poor healing after LASIK, so most surgeons will want to treat the dry eyes first, to ensure a good LASIK outcome. This goes for other types of vision correction surgery, as well.
E-Eye a machine used for the treatment and it is the first and the only medical device in the world using IRPL® (Intense Regulated Pulsed Light) which was designed specifically for the treatment of dry eyes caused by Meibomian glands dysfunction (MGD).
The principal cause of the dry eyes syndrome all over the world was identified as, the Meibomian gland dysfunction. This was the result of the first report about Meibomian Gland Dysfunction (MGD) from the ARVO (the Association for Research in Vision and Ophthalmology) conference that was organized in 2010. Over 50 members, which included some of the biggest experts in Ophthalmology and research gathered from all over the world especially for this event.
The Meibomian Gland Dysfunction, is also called Blepharitis and is generally the cause of dry eye syndrome. It causes the important oil layer in our eyes to become unstable and thinner than it normally should be, which in turn causes an insufficient production tears, or excessive evaporation.
Its now acknowledged that the insufficiency of the external lipid layer of the lacrimal film, produced by the Meibomian glands is the main cause in most evaporative cases.
These glands, which are approximately 80 Meibomian glands located in the upper and lower eyelids of each eye, produce an oil called the lipid layer, avoiding tear evaporation and adapting tears to the irregularities of the eye surface.
These Lipids are non-polarised on the surface, giving stability to the lacrimal fluid and allowing the lubrication of the palpebral conjunctival plan and the contraction of the Riolan muscle allows the lacrimal film to spread out. These Lipids are made up of polarized fatty acids and their fluidity is ensured by the body temperature.
How does it work?
E-Eye is an indirect action and does not directly affect the Meibomian glands. The area “flashed” which is the bub orbital and zygomatic region, are the areas where the parasympathetic nerve passes.
Several neurological studies have proven that the emission on a nerve of infrared as a train of pulse leads to the creation of a micro gradient of temperature between that of the inner and the outer layer of the myelin sheath.
Neurotransmitters are triggered by this micro gradient of temperature. Automatically, the parasympathetic nerve is connected to the Meibomian gland by some of its branches.
The neurotransmitters released would then interact with the glands stimulating the secretion and the contraction of the latter and this will result in the dry lipid layer having a natural flow of lipid, thus reducing the tear evaporation and returning the Meibomian Glands to their normal functions while overall preventing the eyes from getting dry.
