cbd oil and retinitis pigmentosa

Inherited from birth, retinitis pigmentosa is a condition that currently affects an estimated 100,000 people in the US. It causes photoreceptors in the retina to die over time, resulting in severe vision and blindness if left untreated. No cure exists for the disease, but vitamin A regiments have proven beneficial, postponing blindness by up to 10 years in some patients

In fact, a group of researchers from Spain’s University of Alicante published a study earlier this month in the journal Experimental Eye Research that supports this claim. It suggests that cannabinoids may help slow vision loss in the case of retinitis pigmentosa.

Researchers Investigate Cannabinoids, Visual Deterioration

For years medical marijuana has been used to help treat certain conditions that can cause vision loss. The most common example of this is glaucoma, but it is not the only condition for which cannabis may be beneficial.

“Rats treated with the THC-like structure also had 40% more photoreceptors, which play a major role in passing information about visual stimuli to the brain.”

This makes sense considering rats treated with the THC-like structure also had 40% more photoreceptors, which play a major role in passing information about visual stimuli to the brain.

Brief history and target symptomatology: This 37 y/o PhD university research associate was diagnosed with retinitis pigmentosa (RP) at age 14. He experiences progressive vision loss, headaches, depression and insomnia.

Abstract: A 37-year old man with retinitis pigmentosa found relief of associated symptoms with cannabis and subjective slowdown in progression of vision loss.

Previous and current conventional therapies: Supplementation with antioxidant vitamins was ineffective. Serial electroretinopathies (ERG) were discontinued in his belief that the flashes of light caused further damage to his retina and “ophthalmologists only want photographs for their own collection.” His eyeglass prescription is reviewed annually to compensate for his increasing tunnel vision. He has not found significant improvement in his mood with psychotherapy.

Clinical response to Cannabis: Stress reduced;mood, headaches and insomnia have all improved with cannabis use.

Comments: RP is a genetic disease found in 1 in 4,000 people in the US. In patient’s case, it was traced to mutations in both parents’ X chromosome. There is no known cure; valproic acid, gene therapy and retinal transplantation are currently in the research stage. Administration of a THC analog to rats with chemically induced RP has shown reduction in the rate of degeneration of retinal photoreceptors. .
