Pharmaceutical Agents: Certification, Prescribing Authority, and Limitations
Certification
Missouri optometrists may use and prescribe pharmaceutical agents only after obtaining the board's therapeutic certification. Certification requires the education or examination the board specifies, and certified licensees maintain pharmacology continuing education. The certification is noted on the license and can be disciplined separately.
Authority and limits
Certified optometrists may use topical and oral medications for diagnostic and therapeutic purposes within optometric scope-for example, topical antibiotics for blepharoconjunctivitis, anti-inflammatory agents, and glaucoma medications where authorized. Surgery and injectable agents beyond what the board permits remain outside scope. Prescribing must be based on an adequate examination, documented findings, and consideration of contraindications and systemic disease.
Documentation and referral
Record the diagnosis, drug, dose, duration, and monitoring plan. Provide informed consent for treatment and warn about significant side effects. Refer when the condition exceeds optometric scope or fails to respond as expected.
Worked example. A certified optometrist sees a patient with acute anterior uveitis and no hypopyon. She prescribes a topical steroid and a cycloplegic, schedules follow-up in two days, and documents the risks and return precautions. If the patient instead had a corneal ulcer with stromal involvement, referral to an ophthalmologist would be required because management exceeds optometric scope.
Traps. Prescribing for a systemic condition unrelated to the eye; assuming certification covers surgery; skipping documentation of informed consent; failing to check for drug interactions; treating a red eye without measuring vision and pressure.
