Corneal Ulcer After Hours: Treat or Refer?

A 42-year-old contact lens wearer presents at 8 p.m. with a two-day history of a red, painful right eye, photophobia, and blurred vision. He slept in his soft lenses several nights. Visual acuity is 20/100 in the right eye. Slit-lamp examination shows a 2-mm corneal infiltrate with an overlying epithelial defect and a 1-mm hypopyon. Dr. Patel is an Ohio optometrist with a therapeutic pharmaceutical agent certificate. The office has topical fluoroquinolone samples, but no ophthalmologist is on call; the nearest ophthalmologist is 90 minutes away. The patient asks for strong drops and an injection so he can avoid traveling. Dr. Patel considers scraping the cornea in the office to obtain a culture.

1. Identify which actions are within Dr. Patel’s scope and which are not, and explain the judgment call.

Dr. Patel may diagnose the condition, start appropriate topical antibiotic therapy if it is within his therapeutic certificate, and arrange urgent referral. A hypopyon with a corneal infiltrate and epithelial defect is a sight-threatening ulcer, not routine conjunctivitis. The optometrist’s scope includes diagnosis and treatment with therapeutic pharmaceutical agents, but it does not include performing invasive surgical procedures such as corneal scraping or administering an injection into the eye. Those acts require an ophthalmologist. The fact that the patient asks for an injection and that the ophthalmologist is far away does not expand the scope. The correct judgment is to begin covered treatment if clinically appropriate, protect the eye, and transfer care urgently rather than attempt an unauthorized procedure.

2. What referral and documentation steps should Dr. Patel take, and how should he handle the patient’s request to avoid traveling?

Read the worked answer

He should explain that the hypopyon and ulcer require same-day ophthalmology evaluation, telephone the receiving ophthalmologist or emergency department, and document the time of contact, the clinical findings, the treatment started, and the advice given. If the patient refuses transfer, Dr. Patel should document the informed refusal, the risks including permanent vision loss, and the follow-up plan, and should not simply send him home with samples. He may provide a loading dose of a topical fluoroquinolone if that is his standard and within scope, but this does not replace referral. The distance is a logistics problem, not a scope exception. If the patient cannot travel safely, he should arrange the safest available transfer rather than perform an unauthorized scraping.

3. If Dr. Patel treats with drops, does not refer, and sees the patient again in three days, what standard-of-care and disciplinary issues arise?

Read the worked answer

The issue is not whether he used the correct drop; it is whether he met the standard of care for a sight-threatening corneal ulcer. A 1-mm hypopyon with a 2-mm infiltrate warrants urgent ophthalmology involvement. Failing to refer, or delaying referral for convenience, can cause permanent vision loss and supports a finding of negligence or incompetence. The Board can discipline for departure from accepted standards even if the optometrist stays within the statutory scope. Documentation showing a rational plan, risk discussion, and timely referral is protective; a note that merely says recheck in three days is not. The exam distinction is between authorized treatment and competent treatment: both are required.
