Medical Cannabis for Glaucoma — Switzerland 2026

THC lowers intraocular pressure — briefly. For daily glaucoma therapy it's barely practical. We honestly say where cannabis helps and where standard drops stay unbeatable.

THC lowers intraocular pressure by 25–30 % — but only for 3–4 h. That would need 6–8 daily doses, unrealistic. First line remains prostaglandins (latanoprost). Cannabis useful as add-on for pain, anxiety or intolerance. CBD does not lower pressure and can even raise it slightly. CannabisClub members: 50 CHF flat instead of 190.

What the studies show

Hepler 1971 & Merritt 1980: THC lowers intraocular pressure by 25–30 %, but only 3–4 h.

American Academy of Ophthalmology 2019: no recommendation for cannabis first-line — continuous dosing practically impossible.

When cannabis still makes sense

In comorbid pain, migraine or anxiety — the underlying pathology stays on medical therapy, cannabis reduces symptoms.

On intolerance of prostaglandins or beta-blockers, as add-on with ophthalmology approval.

Does insurance cover cannabis for glaucoma?

Practically never as monotherapy. In comorbid pain, possible within an Art. 71a HIO agreement.
