This just published paper is confirming that the long term usage of Omega 3 Fatty Acids are a great supplement for ocular rosacea sufferers. According to the main measures related to ocular rosacea symptoms, 6 months supplementation of Omega 3 FAs, will offer relief to ocular rosacea symptoms – as indicated by the following quantitative measurements ;
- TBUT: tear file break up time – this is the time in seconds for a dry spot to appear on the surface of the eye after a blink occurs. The eye is held open for this measurement, and a dye is used to aid in the detection of the dry spot event. A breakup time of greater than 10 seconds is considered normal, dry eye can be confirmed with a shorter breakup time.
- Schirmer Score – used to measure how quickly your eyes produce tears. A special paper strip is placed on the lower eyelid for around 5 minutes and a measure of much moisture is generated is used to detect dry eye.
- MGS: Meibomian Gland Score – a score relating to the meibomian gland secretion characteristics.
Patients were selected based on sufferers response to the Dry Eye Scoring System (DESS).
The DESS is a questionnaire consisting of 12 questions designed to assess the symptoms of ocular irritation, covering 3 areas: ocular symptoms, environmental triggers and vision-related function [pubmed].
What are Omega 3 Fatty Acids?
O3FAs are polyunsaturated fats that are not made in the body, are essential to life, so must be sourced from our diet.
Foods high in Omega-3 include fish, vegetable oils, nuts (especially walnuts), flax seeds, flaxseed oil, and leafy vegetables
For those missing Omega-3 in their diet, supplements are available.

Objective or purpose: To evaluate the efficacy of dietary omega-3 fatty acids (O3FAs) in rosacea patients having dry eye symptoms.
METHODS: A prospective, interventional, randomized, double-masked, placebo-controlled, multi-centric study was done.
Symptomatic patients with rosacea were recruited based on their response to (Dry Eye Scoring System, DESS©); a score of 0-3 was assigned to dry eye-related symptoms like ocular fatigue, blurring of vision, itching or burning, sandy or gritty sensation, and redness, respectively (DESS©).
Subjects were (n = 130) were randomized to receive either O3FAs (n = 65) or placebo (n = 65) capsules (olive oil) twice daily for 6 months.
Patients were evaluated at baseline, 1, 3, and 6 months.
Change in subjective dry eye symptoms was the primary outcome measure. Change in meibomian gland score (MGS), Schirmer score, and tear film breakup time (TBUT) were the secondary outcome measures.
RESULTS: Repeated-measures ANOVA revealed that there was a significant (p < 0.001) change in symptoms (F(1.506, 88.825 = 315.193), MGS (F(1.336, 78.796 = 84.438), Schirmer score (F(1.322, 78.022 = 86.559), and TBUT (F(1.354, 79.898 = 179.020.559) in O3FA group as compared to placebo group.
Post-hoc test revealed that there was a significant change in dry eye symptoms at all points of time; there was a significant change in MGS, Schirmer score, and TBUT also, but only after 3 months of intervention.
Linear regression established that symptom severity could significantly predict MGS, Schirmer score, and TBUT. There was a significant change in the slope (intercept) of the regression plots in O3FA group as compared to the placebo group.
CONCLUSION: Rosacea patients with dry eye symptoms have significant improvement in symptoms, MGS, TBUT, and Schirmer score, following dietary intervention with O3FAs for 6 months.
Diet and Rosacea and Acne Symptoms
The role of diet in acne and rosacea symptoms has been an active area of research for several years.

Another novel dietary influence in rosacea patients may be the omega-3 and omega-6 fatty acids. Recently, there is evidence in the ophthalmology literature that supplements or foods that contain such fatty acids may help with dry eyes.33 Some dermatologists have been using flax seed oil that contains high levels of omega-3 fatty acid to help combat ocular rosacea.

It might take as long as 6 months, but would you be willing to give O3FAs a try ?
