8. Where an optometrist administers or prescribes a medication or provides eye care, the optometrist must refer the patient to a physician if the patient’s condition does not adequately respond to treatment in the accepted or anticipated amount of time and each time the patient’s interest requires it. An optometrist must also refer the patient to a physician if the signs and symptoms suggest a condition other than the condition referred to in section 3 or that requires a physician to take charge of the patient, in particular where there is the presence of(1) an infectious ulcer reaching the central cornea;
(2) epithelial dendrites with stromal injury;
(3) sectorial inflammation of the episclera with ischemia or melting;
(4) sectorial inflammation of the anterior chamber with hypopyons, vitritis or atypical lesions of the cornea;
(5) glaucoma other than those for which the optometrist is authorized to intervene pursuant to section 5.
