The claim
Posts online say that curcumin (turmeric) helps with glaucoma.
Where research stands
We found 4 published papers on curcumin (turmeric) and glaucoma. They were published between 2013 and 2026. None of them is a study in people. 2 were studies in animals, and 1 was only in cells in the lab. 1 paper is a review that sums up other studies.

Verdict
Curcumin (turmeric) has been studied for glaucoma in animals, not yet in people.
Unproven means: it was only tested in animals or cells, or there is too little or mixed data from people. How we rate claims
What this means for you: Results in animals or in cells often do not hold in people. Do not stop or change your medicines because of it. Ask your doctor before you start taking it.
