Figure 3: The orbicularis roll. Note the reduced palpebral fissure height upon smiling due to the orbicularis roll in a young person (top left). The same after two units of Botulinum toxin in the mid-pupillary plane in the pre-tarsal orbicularis of the lower eyelid (top right). Note the widened palpebral fissure with the same amount of smile expression. With ageing, the static lines (bottom left) and dynamic lines (bottom right) over the orbicularis roll increase
