TPA Certification Does Not Cover Glaucoma
Dr. Alvarez is a Massachusetts-licensed optometrist with TPA certification but no TPA+GC certification. She examines a 64-year-old man who reports mild blur and occasional halos but no pain, nausea, or redness. Best-corrected acuity is 20/25 OD and 20/30 OS. Goldmann tonometry is 34 mmHg OD and 31 mmHg OS. Gonioscopy shows open angles. Optic discs show a 0.75 cup-to-disc ratio OD with inferior rim thinning; a reliable 24-2 visual field shows an early superior arcuate defect OD. She has not obtained prior records, and this is the first documented pressure measurement in her office. Dr. Alvarez has a 4-week follow-up opening and wants to start generic latanoprost nightly, then refer only if the pressure does not fall. The patient prefers to stay with her.
1. May Dr. Alvarez initiate latanoprost and manage the patient with a 4-week follow-up? Explain the scope-of-practice rule that controls.
Read the worked answer
Issue: Whether a TPA-only optometrist may diagnose and treat glaucoma.
Rule: Massachusetts law limits optometric prescribing to the agents and conditions covered by the optometrist's certification. TPA certification allows therapeutic drugs for conditions within optometric scope; glaucoma and glaucoma-suspect management requires the separate TPA+GC certification. The Board treats prescribing outside certification as practicing beyond scope, regardless of the drug's safety.
Application: IOP 34/31, a 0.75 cup-to-disc ratio with rim thinning, and a reproducible arcuate defect indicate glaucoma or a high-risk suspect. Latanoprost is glaucoma therapy, not a temporary measure. A 4-week follow-up is disease monitoring. Dr. Alvarez lacks the credential that authorizes either.
Conclusion: She must not start latanoprost. She should document the findings, explain the diagnosis and urgency, refer to an ophthalmologist or TPA+GC-certified optometrist, and record that referral. If she prescribes and refers later, she has engaged in unauthorized treatment; Board exposure includes discipline for a scope violation and prescribing without certification, plus malpractice risk if the patient loses vision while she monitors.
2. What must Dr. Alvarez do at this visit, and what should the record contain?
Read the worked answer
She should complete and document the glaucoma workup, including repeat tonometry, gonioscopy, optic nerve evaluation, and visual field results. The record should state the working diagnosis, the reason glaucoma management is outside her certification, the urgency, the specific referral destination, and that the patient was informed. She should not write a prescription or schedule a routine follow-up as a substitute for referral. If the patient refuses referral, document the informed refusal, the risks of vision loss, and the efforts made. She may provide education and monitor non-glaucoma findings within scope, but she may not create a de facto glaucoma treatment plan. The record should also note that prior records were requested. This documentation supports continuity of care and demonstrates that she recognized the scope limit rather than ignored it.
3. Suppose Dr. Alvarez writes the prescription to help the patient and refers two months later. What Board exposure does she face?
Read the worked answer
The Board can treat the prescription as unauthorized glaucoma treatment. The violation is not cured by the later referral or by the patient's preference. Aggravating facts include that she had not obtained prior records, that the findings were unambiguous, and that she continued monitoring during the two months. The Board may investigate a complaint, subpoena records, and impose discipline ranging from reprimand to suspension, with conditions such as extra CE or practice restrictions. Separate exposure exists for prescribing without current TPA+GC authority and for failing to refer promptly. The patient's vision outcome may drive a malpractice claim, but the Board case turns on the scope violation and the prescribing itself.
