Get a load of that summary. (My highlight, below.) I wonder if the word "novel" has a specific medical definition in this context which is somehow escaping me. It seems to me that MDs and ODs have been pushing flax or fish oil on their dry eye patients forever, certainly since before the (in)famous Harvard tuna study.

Nutritional supplements for dry eye syndrome.

PURPOSE OF REVIEW:
Essential fatty acids have been of interest in the treatment of systemic and ocular diseases, and is most recently of interest in the area of dry eye disease.

RECENT FINDINGS:
Systemic and topical omega-3 fatty acids and omega-6 fatty acids have been used recently as an adjunctive treatment for patients with dry eye disease. They appear to have efficacy against the symptoms of dry eye that many patients experience. This symptom is postulated to be secondary to the anti-inflammatory effects that have been previously described. Although this effect is promising, more investigation is warranted in order to standardize indication for use, and composition and dosing for treatment.

SUMMARY:
The use of essential fatty acids as a nutritional supplement is a novel treatment for patients with dry eye syndrome.
