5. Notwithstanding section 1, an optometrist who holds a permit referred to in the second paragraph of section 19.2 of the Optometry Act (chapter O-7) may, in cases of glaucoma, renew or change a prescription for anti-glaucoma medications.
The optometrist must, however, prior to every renewal or change, obtain verbal or written approval from the original prescribing physician or from the physician designated by the original prescribing physician. The optometrist must, in addition, write the name and professional permit number of the physician from whom consent was obtained on the prescription.
