Cannabinoids have been proven to help slow vision loss in those afflicted with retinitis pigmentosa

Medical Cannabis has been used in many countries, for many years to help treat conditions causing vision loss. The most common of these circumstances is glaucoma. Researchers from the Spain’s University of Alicante published a study in the Journal Experimental Eye Research stating just this, suggesting that cannabinoids have been proven to help slow vision loss in those afflicted with retinitis pigmentosa.

Retinitis pigments are one of those conditions that affect a large number of people. In the United States, it affects 100,000 people alone. Causing photoreceptors in the retina to progressively die over time, this condition ends results in blindness if left untreated. Though this degenerative disease has not been found to have a cure, vitamin A regiments have proven to help, lengthening the time that one reaches blindness.

In the study, the treatment group of whom received synthetic THC cannabinoid (100 mg/kg) each day, showed improvement and responded much better in vision tests than the other group not receiving treatment.

This coincides with studies involving rats treated with the synthetic THC.

Though more research is expected to find out what mechanisms are responsible, the study’s lead author Dr. Nicolás Cuenca, anticipates further evidence to present itself with continued research.
