Omega-3s Provide Relief From Dry Eye

Keratoconjunctivitis sicca, commonly called dry eye, is often a chronic condition that can result in irritated, gritty, scratchy or burning eyes, excess watering and blurred vision. A recent study suggests that combining omega-3s with omega-6 fatty acids and other important nutrients may help combat dry eye.

Participants in the study included 38 post-menopausal women with moderate to severe dry eye. Over the course of six months, half of the group took a supplement consisting of gamma-linolenic acid (GLA – a form of omega-6), omega-3s, antioxidants, and other nutrients. The other half of the group took a placebo.

At the conclusion of the study, the supplement group reported improvements in irritation symptoms, ocular surface inflammation, and corneal surface smoothness. Ocular surface inflammation is one of the main factors that causes dry eye, and roughness in the corneal surface leads to distorted vision.

The placebo group, on the other hand, showed worsened symptoms by the end of the trial.

Researchers from Eastern Virginia Medical School conducted the study. It was published online ahead of print on July 23, 2013, in Cornea.

Omega-3s have been linked to a number of health benefits, including alleviating arthritis pain, better moods, improved joint mobility, helping with age related macular degeneration, and aiding your immune system.

Because omega-3 fatty-acids are not found naturally in the human body, it is especially important to make sure that they are a part of your daily diet. Oily, dark fish such as tuna and salmon are high in DHA and EPA omega-3s.
