|(a) In the event of the death or retirement of an optometrist who was practicing optometry in a partnership, or with a professional corporation or professional association, the surviving members of the professional corporation or association may, with the written permission of the retiring optometrist, or the deceased optometrist's legal representative, continue to practice with the name of the deceased or retired optometrist. (b) The fact that such optometrist is retired or deceased shall be clearly displayed in such a manner that such facts will be clearly visible to the public prior to entry of the optometrist's office or reception area.
