When used for glaucoma treatment, marijuana has been shown to lower IOP but its effects are limited to 3–4 h, requiring dosing of 8–10 times per day for sustained therapeutic effect.[26] Furthermore, only 60–65% of individuals experience IOP reduction with the use of marijuana.[26] A cross-sectional survey showed that factors that contribute to patients' intentions to use medical marijuana for glaucoma treatment were younger age, lower level of education, and prior marijuana use.[27] Several patient perception factors also demonstrated significant positive correlations with the intention to use medical marijuana, including notions supporting legalization of medical marijuana, false beliefs regarding marijuana's efficacy in glaucoma treatment, and disregard for the costs of its purchase. However, patient satisfaction with current glaucoma management exhibited a strong negative correlation with the intention to use marijuana for glaucoma treatment, highlighting the importance to evaluate patient's satisfaction with the current treatment.[27] In a statement issued in 2010, the American Glaucoma Society recommended against the use of marijuana in the treatment of glaucoma given its short duration of action, its documented adverse effects, and the lack of scientific evidence to date that its use could slow or stop the progression in glaucoma.[28]
