Omega-3s May Help Reduce Glaucoma Risk Factor

Elevated intraocular pressure (IOP) is the major modifiable risk factor for glaucoma. A recent study suggests that oral supplementation of omega-3s may help reduce IOP.


Participants in the study included 105 people between the ages of 33 and 38 with IOP, and without a current or prior diagnosis of glaucoma. Seventy-two of the participants were given oral omega-3 supplements containing 1,000 mg of EOA, 500 mg of DHA, and 900 mg of ALA, while the remaining 33 were given 1,500 mg of olive oil as a placebo. The participants followed their interventions daily for three months. IOP was measured at baseline and after 3 months of supplementation.


At the conclusion of the study, the researchers noted a 8% reduction in IOP in the omega-3 groups, while the control group had a slight increase. They were also associated with an increase in docosanoids, which is associated with lower intraocular pressure.


Researchers from the University of Melbourne conducted the study. It was published on May 1, 2018, in Translational Vision Science and Technology.


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 omega-3s. For people who don’t like fish, consider taking a daily high quality non-fish supplement that has been tested for purity and potency.
