PB-Marijuana and Driving: Your Retina and Brain
Marijuana impacts cognition and sensory functions. The impairment is enough to create a serious hazard to driving. The rate of drivers testing positive for marijuana only in a fatal accident, has doubled in Washington and Colorado since the legalization of marijuana. Marijuana causes dysfunction in retinal processing. Marijuana inhibits up to 75% of the visual functions in the lateral geniculate nucleus, the primary brain relay nucleus. Little is known about what levels of marijuana and its primary ingredients; Cannabidiol (CBD) and Tetrahydrocannabinol (THC), impair functions enough to impact driving. Further there is no functional test available to law enforcement to support dysfunction even when the blood levels of measured THC is considered to be high enough to impair function. There is research using functional Magnetic resonance imaging that the visual system has dysfunction with acute and chronic use of marijuana. This lecture will review the available research related the visual pathway and its relationship to driving and cannabis use.

AOA Expiration Date:
In response to Hurricane Ian, the federal government takes steps to ease the pains of disaster recovery in Florida. Learn more about the federal waivers—and how you can help colleagues affected by disaster.
The AOA has created a trove of practice management tools and services that can power practices forward in a profession and health care landscape that increasingly demands doctors practice at their highest levels and creates greater opportunities to develop and empower paraoptometric staff. These days, change is out of necessity.
