The journal Cornea recently published a placebo controlled, double masked, randomized, prospective study on Omega 3 fatty acid (fish oil) supplements and the treatment of 36 patients with dry eye. The study lasted 90 days. The patients completed the Ocular Surface Disease Index (which can be downloaded on our Cornea and external disease section of our website) to grade their subjective symptoms of dry eye. At the completion of the study 70% of the group taking the Fish oil supplements were symptom free. Only 7% of those taking he placebo pill were symptom free.
Fish Oil is a common supplement recommended for many inflammatory diseases. The underlying cause of dry eye is inflammation. We recommend a pharmaceutical grade fish oil as part of our dry eye treatment, along with other topical drops and environmental modifications.
