Acute Angle-Closure in a Rural Setting
A 68-year-old woman presents at 4:45 p.m. to a solo optometry practice in Aroostook County with a 6-hour history of severe right eye pain, blurred vision, colored halos, nausea, and vomiting. Visual acuity is 20/200 OD and 20/20 OS; IOP by Tonopen is 54 mmHg OD and 16 mmHg OS; the right cornea is hazy and the pupil is mid-dilated and fixed. The optometrist holds a current Maine license with therapeutic pharmaceutical agent privileges and has no Board restrictions. The nearest ophthalmologist is 90 minutes away and the roads are icy. The OD administers one dose of oral acetazolamide 500 mg, topical timolol 0.5%, and pilocarpine 2%, then calls the on-call ophthalmologist, who agrees to meet the patient at the emergency department. The patient's IOP falls to 38 mmHg before transfer. The OD documents the findings, drugs, times, and transfer but does not create a separate informed-consent form for the oral medication.
1. Was initiating oral acetazolamide within the OD's Maine scope, and which facts in the scenario matter most to that analysis?

Two questions must be separated. The legal-scope question is whether a Maine-licensed optometrist with therapeutic privileges may initiate an oral medication for an ocular condition. Under the Practice Act and Board rules, the answer is generally yes for therapeutic pharmaceutical agents, including oral agents, when the licensee holds the privilege and no Board order restricts it. The facts here-current license, TPA privileges, no restrictions-satisfy the credential side. The standard-of-care question is clinical: acute angle-closure glaucoma is an emergency, and oral acetazolamide plus topical IOP-lowering is accepted temporizing therapy only while definitive ophthalmologic care is arranged. The 90-minute transfer and icy roads make temporizing reasonable, but the OD must not delay transfer to complete a workup. The OD should also screen for sulfonamide allergy and renal issues if time permits and document why transfer was chosen.
2. The OD did not use a separate consent form for the oral medication. What record-keeping and consent issues does that create?
Read the worked answer
The separate form is not the legal test; the record is. Maine record rules require documentation sufficient to identify the patient, the findings, the drug, dose, route, time, and the plan. Informed consent for an emergency medication can be documented in the note-risks, benefits, alternatives, and patient questions-rather than on a standalone form. The note as described lacks any consent discussion. The OD should add a late entry only if permitted by the Board's record rules; do not backdate. The better practice is a checklist for emergency medications. The absence of a separate form is not automatically a violation, but the absence of any documentation of consent is a weakness.
