Do your eyes itch? Do you suffer from burning, chronic redness or a crudiness in your eyes. You may be one of 10 million who suffer from some form of Dry Eye Syndrome.
Our tears are made up of three important layers. When too few tears are produced the tear film can break down causing dry spots to develop.
As a result, the condition known as Dry Eye Syndrome occurs. Dry Eye cannot be cured but your Eye Care Professional can prescribe treatment to help alleviate the symptoms so that your eyes stay healthy and your vision unaffected.
Dry Eye is commonly caused by the natural aging process. Dry Eye can also be caused by looking at a computer monitor too long. Environmental factors like, sun, wind, dust, and smoke are other causes of your Dry Eye. Medications like antihistamines, diuretics, tranquilizers and sleeping pills can also lead to Dry Eye.
For most people, the use of an artificial tear substitute is the most common method for treatment of Dry Eye Syndrome.
Dry eye is a chronic condition that results from an insufficient amount of tears or excessive evaporation of the tear film. Dry Eye affects millions of people worldwide and is one of the most common reasons a patient will visit their Eye Doctor. Dry Eye is usually associated with dryness, scratchiness or burning of the eye. Some people experience a foreign body sensation, a feeling that something is in the eye. The condition can also produce watery eyes, because dryness can stimulate excess tearing as a reflex. In its early stages dry eye causes mild discomfort but it may become very uncomfortable as the condition progresses. One of the keys to improving this condition and avoiding damage to the eye is to recognize the symptoms of Dry Eye early and seek treatment for it. Without treatment, chronic Dry Eye can lead to eye infections, scarring and possibly impaired vision.
Risk Factors
A person’s age, health, environment and lifestyle can effect ones risk of developing Dry Eye. Dry Eye is more common in people over the age of 40, especially in women around the age of menopause. Patients with systemic inflammatory such as Rheumatoid Arthritis, Lupus, Rosacea or Sjogren Syndrome are also at risk. Certain medication can worsen Dry Eye and its symptoms. These can include certain medication for the treatment of depression, high blood pressure, allergies, hormone replacement therapies and diuretics. While they are not the root cause of the condition, environmental factors, including pollution, dry weather and persistent wind can worsen the symptoms of Dry Eye. Heat and air conditioning can create similar environmental conditions in doors. Everyday activities, such as driving, reading, focusing on a computer screen or watching television can also worsen Dry Eye symptoms.
Cause
Dry Eye has many causes. Some causes are from many external influences. Other causes are the changes in the bodies nervous, hormonal and immune systems that can occur over time. When a person has chronic Dry Eye, inflammatory changes in the tear producing glands and in the eyes surface can interfere with the production of normal tears. This occurs when the eye produces fewer tears that are less effective. This results in a tear film that evaporates more quickly than normal which provides less moisture and protection for the eye surface with the tear films protection diminished. The eyes may experience painful symptoms of dry eye and damage to the eye surface may occur.
Testing
Testing for Dry Eyes is performed after evaluating a patients symptoms and medical history. A standard Dry Eye questionnaire may be used providing a score for Dry Eye conditions. The patient will answer based on their symptoms such as persistent dryness, scratching, burning or a gritty sensation in the eye. In addition to evaluating symptoms there are a number of simple tests that can be used to diagnosis Dry Eye. These tests show how many tears the patient produces, how quickly tears evaporate and if there is damage to the surface of the eye.
Treatment Overview
Millions of people suffer from Dry Eye Syndrome. Fortunately there are numerous treatments available to release the symptoms for Dry Eye. Artificial tears which come in liquid, gel, and ointment form are used to temporally moisten and lubricate the eyes. Another solution is to block the drainage canal that carries tears away from the eyes surface keeping tears from escaping the eye. Some patients are candidates for prescription medications that can increase tear functions and production. Prescription steroid drops work in a similar fashion by reducing inflammation in the tear producing glands of the eye. Eye Care Providers are also discovering the benefits of nutraceuticals. These nutrition based options may help to lesson the symptoms of Dye Eye.

Blepharoplasty can rejuvenate puffy, sagging or tired-looking eyes by removing excess fat, skin and muscle from the upper and lower eyelids. It may be performed for cosmetic reasons or to improve sight by lifting droopy eyelids out of the patient's field of vision. The procedure is usually performed in an office with local anesthesia in as little as 45 minutes. Blepharoplasty can be combined with a facelift or BOTOX® treatments to raise the eyebrows or reduce the appearance of wrinkles, crow's feet or dark circles under the eyes.

Patients with diabetes are at an increased risk of developing eye diseases that can cause vision loss and blindness, such as diabetic retinopathy, cataracts and glaucoma. These and other serious conditions often develop without vision loss or pain, so significant damage may be done to the eyes by the time the patient notices any symptoms. For this reason it is very important for diabetic patients to have their eyes examined once a year. Diagnosing and treating eye disease early can prevent vision loss. It is also important to maintain a steady blood-sugar level, take prescribed medications, follow a healthy diet, exercise regularly and avoid smoking.

The macula is a part of the retina in the back of the eye that ensures that our central vision is clear and sharp. Age-related macular degeneration (AMD) occurs when the arteries that nourish the retina harden. Deprived of nutrients, the retinal tissues begin to weaken and die, causing vision loss. Patients may experience anything from a blurry, gray or distorted area to a blind spot in the center of vision.
AMD is the number-one cause of vision loss in the U.S. Macular degeneration doesn't cause total blindness because it doesn't affect the peripheral vision. Possible risk factors include genetics, age, diet, smoking and sunlight exposure. Regular eye exams are highly recommended to detect macular degeneration early and prevent permanent vision loss.

Here at the Advanced Vision Institute, we administer eye exams to test for myopia, hyperopia and astigmatism and help your optometrist provide a proper prescription if eyeglasses or contact lenses are needed. Eyewear may be used for certain activities, like watching television or driving, or may be worn at all times.
- Myopia (nearsightedness) is a vision condition affecting nearly a third of people in the United States. A myopic eye focuses properly on nearby objects, but distant objects appear blurry. This imbalance typically occurs because the cornea either has an oblong shape or is excessively curved, so that only some of the light entering the eye focuses on the retina. The most common symptom is difficulty seeing objects in the distance, for example a chalkboard or television screen. The condition usually develops before the age of 20.
- Hyperopia (farsightedness) occurs when the cornea is too flat or irregularly shaped, causing nearby objects to appear blurry while objects in the distance are clear. Common signs of hyperopia include difficulty maintaining a clear focus on nearby objects, and eyestrain or headache after close work.
- Presbyopia is a natural change in our eyes' ability to focus. It occurs when the soft crystalline lens of the eye starts to harden. This loss of flexibility affects the lens' ability to focus light in the eye, causing nearby objects to look blurry. Presbyopia happens to everyone starting in about our 40s or 50s -- even in patients who have had laser vision correction. The effects of presbyopia can be corrected with glasses or contact lenses, including bifocals and multifocals; multifocal lens implantation, including Crystalens™, ReZoom® and ReSTOR®; conventional surgery; and monovision LASIK. Laser surgeries such as conventional LASIK, PRK and LASIK cannot correct presbyopia because they reshape the cornea rather than treat the lens.
- Astigmatism is the term for when the cornea is oblong rather than spherical in shape. This irregular curvature prevents light from focusing properly on the retina. As a result, objects that are close or at a distance may appear blurry or doubled. Astigmatism can cause headaches, eyestrain and fatigue to blurred or distorted vision. Most people have some degree of astigmatism, which often occurs in combination with myopia or hyperopia. Regular astigmatism is found in 30-40% of people who wear glasses.

Over 140 million people in the U.S. wear eyeglasses, and over 30 million wear contact lenses. Glasses and contact lenses improve vision by adjusting the way the eyes bend and focus light. Ideally, light rays are refracted (bent) as they pass through the cornea so that they focus on the retina in the back of the eye. In a healthy eye, this means that objects can be seen clearly. However, many people’s corneas have a shallow or steep curvature which causes light rays to focus in front of or behind the retina. Objects may then appear blurry at certain distances or at all distances.
Glasses and contact lenses correct these refractive errors. Prescriptions are measured for each eye so patients can enjoy optimal vision clarity, usually 20/20. Eyewear may be used for certain activities, such as reading for farsighted (hyperopic) patients and driving or watching television for nearsighted (myopic) patients, or may be worn at all times.
Regular eye exams test for the development and progression of refractive errors and help your optometrist provide a proper prescription if eyeglasses or contact lenses are needed. Exams are also an invaluable tool in the early detection of eye disease.
