Condition

Ocular Hypertension

Ocular hypertension is eye pressure above the usual range, typically over 21 mmHg, without damage to the optic nerve, and it is the main risk factor for glaucoma. Cannabis is the one option with reported findings: two small studies found eye pressure went down, though the evidence is limited. Those studies included only six people in total, so the results are early hints rather than firm answers.
