Can someone tell me a little about the difference between DPA and TPA. I know that one is diagnositic and one is therapeutic, but... can't say I really know what those words mean in reference to classes of drugs. I know that every state has DPA privileges available to optometrists, but are there still some states without TPA privileges? Thanks.
I'm only familiar with SC, but its a start.
A diagnostically certified OD can only use medications for diagnostic purposes. In SC, those medications are limited to "anesthetics, mydriatics, cycloplegics, miotics, dyes, and over-the-counter drugs". So, basically, diagnostically certified ODs in South Carolina can diagnose disease but can't actually do anything about it, pharmaceutically anyway.
Therapeutically certified OD can do everything a diagnostically certified OD can, plus prescribe drugs. What drugs are allowed varies from state to state. SC allows all topical drugs (although steroids can only be used for 21 days before consulting an MD). Oral meds are limited to "antihistamines, antimicrobial, antiglaucoma, over-the-counter drugs, and analgesics for the treatment of ocular and ocular adnexal eye disease" and analgesics only for 7 days (plenty of time for corneal abrasions to heal up).
Last I checked, which was back in April, every state had therapeutically certified ODs with some Rx rights. What drugs varies considerably. The AOA has a page on their website that shows what states have what rights. Seeing as I'm not an OD, I can't access it. Perhaps someone else could look that up and post anything relevant.
