Kelulut honey as an add-on treatment for juvenile open-angle glaucoma

Official title: Supplementary Kelulut Honey Therapy in Juvenile Open-Angle Glaucoma: Effects on IL-6, RNFL and Dry Eye.

Run by Universiti Sains Malaysia · NCT07396441 · Data updated 2026-11-12

This trial will test whether taking 30 g of Kelulut (stingless bee) honey daily for three months helps lower inflammation, protect retinal nerve fibers, and improve dry eye in people aged 15–40 with juvenile open-angle glaucoma who are already on standard treatment.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are people aged 15–40 diagnosed with juvenile open-angle glaucoma who are compliant with conventional treatment, have achieved target intraocular pressure, and have no allergy to honey or major systemic comorbidities like diabetes or autoimmune disease.

Probably not a fit

Patients with diabetes, other retinal or optic nerve diseases, systemic neurodegenerative conditions, recent use of steroids or antioxidant/herbal products, or those who cannot comply with at least 75% adherence are unlikely to benefit or be eligible.

What this trial studies

This is a randomized, multicenter, phase 4 trial in Malaysia enrolling 60 patients with juvenile open-angle glaucoma who have achieved target intraocular pressure on standard therapy. Participants are assigned by center to a honey group that consumes 30 g of Kelulut honey daily for 90 days or to a control group that receives usual care without honey. Outcomes before and after the intervention include serum interleukin-6 (IL-6), retinal nerve fiber layer (RNFL) thickness, tear break-up time (TBUT) and Schirmer Test 1, with compliance tracked by daily diaries and return of used sachets. Blood samples are processed centrally and ocular imaging and dry eye tests are performed using standardized protocols, with allergic reactions or adverse events leading to discontinuation as needed.

Why it matters

Potential benefit: If successful, the supplement could reduce ocular or systemic inflammation, slow RNFL thinning, and improve dry eye symptoms as a low-risk adjunct to existing glaucoma care.

How similar studies have gone: There is limited clinical evidence for honey in glaucoma specifically; some small studies suggest anti-inflammatory or ocular-surface benefits from honey or related products, but this application is relatively novel and not yet well established.
