Scope of Practice and Prescribing Authority
What the domain tests
This domain asks where North Dakota law draws the boundary of optometric practice and how far prescribing authority extends. Exam items are usually scenarios: a patient presents, and you decide whether the optometrist may diagnose, treat, prescribe, or must refer.
Core rules and concepts
- NDCC ch. 43-13 defines optometry as examining, diagnosing, and treating the visual system and eye conditions, including prescribing corrective lenses, contact lenses, low-vision devices, and authorized pharmaceutical agents.
- Prescribing authority comes from the statute and board rules, not from the license title alone. The rules identify authorized diagnostic and therapeutic agents and any limits; controlled substances also require DEA registration and compliance with federal law.
- Drugs or procedures outside the authorized scope are prohibited even if the optometrist feels competent. The correct response is referral or comanagement.
- Delegation, supervision, and telehealth prescribing must fit board rules; do not assume they are unrestricted.
Worked example
A patient has a painful red eye, a fixed mid-dilated pupil, and a hazy cornea. The presentation suggests acute angle-closure glaucoma, an emergency. The optometrist may recognize the condition and arrange emergency referral, but must not treat it as routine conjunctivitis or delay transfer for a routine follow-up. The reasoning: the license permits diagnosis, but statutory scope and the standard of care require immediate escalation when the condition exceeds authorized management or threatens sight.
Traps that cost marks
Do not equate an optometry license with unrestricted medical practice. Do not prescribe outside the authorized formulary. Do not treat self, family, or friends outside board rules. Do not let a busy schedule convert an emergency into a routine visit.
