In my practice and at NaturalEyeCare.com we know that the eyes are the windows to the soul and windows that reveal the state of your overall health.

A new story over at Yahoo Health lists 14 different conditions that can be recognized by looking into your eyes.

The list includes Computer Vision Syndrome, also known as Computer Eyestrain. Red, burning eyes as well as blurred vision, dizziness, and trouble concentrating are all signs of eyestrain from excessive computer use.  Visit our pages on computer eyestrain for tips on how to prevent and treat it.

Blepharitis, or inflammation of the eyelids, also made this list because they say it can be linked to acne rosacea.  Inflammed eyelids can also be a sign of allergies and sensitivities to foods or the environment.  It can even be a reaction to certain prescription or over the counter drugs – see more on drugs that harm the eyes.

Dry eyes are the most common complaint brought to eye doctors.  They can be indicative of rheumatoid arthritis, diabetes (especially when the blood sugar is up), asthma, thyroid disease (lower lid does not move when blinking), lupus, and possibly glaucoma.  Dry Eye Syndrome itself can be treated with several natural remedies.

Dry eye syndrome can be a difficult condition to cope with, especially if you are a contact lens wearer.

Many patients found that the eye drops that can be purchased at the pharmacy don’t work, and can even be hazardous to use – eye drops that contain preservatives can aggravate dry eye symptoms, and even kill corneal cells. Eye drops that promise to “get the red out” will reduce circulation in the eye, decrease production of the tear film, and worse, eventually make your eyes even drier.

A study published in Contact Lens and Anterior Eye showed that the omega-6 fatty acids in evening primrose oil can help reduce dry eye symptoms in female contact lens wearers.  After six months, the women in the trial who were administered evening primrose oil reported less eye dryness than those who received the placebo (olive oil).

Researchers are examining dry eye syndrome‘s relationship to meibomian gland dysfunction and other eye conditions.

According to The Cornea & Contact Lens Society of New Zealand, “meibomian glands are the oil-producing glands located in both the upper and lower eyelids… This oil helps to stop the water in the tears from evaporating, thus helping to prevent dry eyes.”  Dry eye symptoms can result when this stabilizing oil does not reach the tear film.

Spanish scientists publishing in Cornea found that nearly 50% of subjects with dry eye also had meibomian gland dysfunction.

In this study, it was also concluded that “Pterygium, trauma, cataract surgery, pseudoexfoliation, and glaucoma are associated with signs of dry eye.”

Researchers have found a link between diabetic retinopathy and dry eye syndrome.  More than 50% of type 2 diabetes patients enrolled in a study at Yazd Diabetes Research Center exhibited dry eye symptoms in addition to their main complaint of diabetic retinopathy.  Study authors acknowledge a connection between the conditions, but state that further research is necessary to establish a causal relationship between the two.  They do state that “examination for dry eye should be an integral part of the assessment of diabetic eye disease.”

A new study shows that early diagnosis and treatment of dry eye syndrome in diabetic patients may help prevent problems such as scarring and perforation of the cornea and secondary bacterial infection.

Scientists at the Yazd Diabetes Research Center evaluated 199 type 2 diabetic patients for dry eye syndrome and other factors.  Of the 199 subjects, 108 patients (54.3%) were found to suffer from dry eye syndrome.

Although dry eye syndrome was more common in older and female patients, this association was not significant.  However, researchers did find a significant association between dry eye syndrome and duration of diabetes.   Researchers also noted that dry eye syndrome was more frequent in diabetic patients with diabetic retinopathy (DR). 

Study authors concluded that dry eye syndrome in diabetic patients may be a contributor for a variety of corneal complications including superficial punctuate keratopathy, trophic ulceration, and persistent epithelial defect.   The authors recommended that examination for dry eye should be an integral part of the assessment of diabetic eye disease.

A recent study shows that consumption of omega-6 fatty acid may help alleviate dry eye symptoms and improve overall lens comfort in patients suffering from contact lens-associated dry eye.

Researchers evaluated the effects of oral treatment with omega-6 fatty acids in the form of evening primrose oil (EPO) on subjective symptoms, ocular surface signs and tear film characteristic in patients with contact lens-associated dry eye.

76 female soft contact lens wearers were treated for six months either with omega-6 fatty acids in the form of EPO or placebo (olive oil). The patients were given three examinations (baseline, three and six months) to test tear film characteristics (tear meniscus height, break-up time), meibomian gland function (lipid layer thickness and quality) and ocular surface parameters (hyperemia and staining). At each examination the women were given a questionnaire relating to lens comfort and dry eye symptoms.

The EPO group showed a significant improvement in the specific symptom of “dryness” at three and six months as well as a significant improvement in overall lens comfort at six months. Tear meniscus height was increased in the EPO group at six months relative to baseline, although all other objective signs were unchanged.

These findings support a 2003 study on omega-6 fatty acids which evaluated the effect of systemic linoleic acid (LA) and gamma-linolenic acid (GLA) on patients with dry eyes.

GLA is an essential fatty acid in the omega-6 family that is found primarily in plant-based oils, such as evening primrose oil, black currant seed oil, and borage seed oils. Essential fatty acids help the body’s natural ability to fight inflammation, but cannot be made in the body and must be obtained from food. LA, another omega-6 fatty acid, is found in plant oils such as safflower oil and is converted to GLA in the body.

In a randomized clinical trial, 26 patients with dry eye (aqueous-deficient keratoconjunctivitis sicca) were randomly divided into two groups of 13 patients each. The study group received tablets containing LA (28.5 mg) and GLA (15 mg) twice daily for 45 days; the control group received a placebo tablet for 45 days.

The results? Researchers found that therapy with LA and GLA and tear substitutes reduced ocular surface inflammation and improved dry eye symptoms.
