Maqui Berry Shown to Improve Dry Eye Symptoms
Dry eye syndrome occurs when tears evaporate too quickly, or the eye does not produce enough tears. Dry eye symptoms include stinging and burning eyes, red or irritated eyes, gritty eyes, and eye fatigue. A new suggests that maqui berry extract may help improve dry eye symptoms.
Participants in the study included 74 adults aged 30 to 60 years. All of the participants had eye dryness and eye fatigue and were exposed to more than four hours of screen time daily at work. Half of them received 60mg day of maqui berry extract, and the other half received a placebo daily for four weeks.
At baseline and at four weeks, the researchers measured eye dryness and fatigue using the Schirmer’s test, the tear break-up time test, pupillary response, and the flicker test. The Dry Eye-Related Quality of Life Score questionnaire was used to assess subjective symptoms such as sensations of grittiness, sore eyes, and red eyes.
At the end of the study period, participants in the maqui berry group showed significantly higher lacrimal fluid production in both eyes, compared to the placebo group. The maqui berry group also showed significant reductions in eye fatigue, stiff shoulders, sensations of grittiness, sore eyes, and red eyes.
The study was conducted by researchers from Ario Nishiarai Eye Clinic. It was published online ahead of print on November 22, 2018 in the Journal of Traditional and Complementary Medicine.
