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.

In this dry eye study, it shows that the GLA group showed a significant improvement in the specific symptom of ‘dryness’ at 3 and 6 months (p <0.01) as well as significant improvement in overall lens comfort at 6 months (p<0.01). Tear meniscus height was increased in the GLA group at 6 months relative to baseline (p<0.01), although all other objective signs were unchanged.

GLA (gamma-linolenic acid), an omega-6 fatty acid with anti-inflammatory properties can be found in oils derived from black currant seeds and the evening primrose plant. Several small trials testing GLA and linoleic (LA) oil in dry eye syndrome with an inflammatory component report reduced ocular surface inflammation and symptom improvement.

A recent study done at the Catholic University of Korea showed that using eyedrops containing retinal palmitate daily for 4 weeks can effectively relieve the symptoms of dry eyes and improve tear film production.

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.
