Analysis of senile changes in the palpebral fissure.

This work was carried out to determine the changes in conformity and physiological movements of the eyelids with advancing age. Some conceptions fostered in the literature are false and should be discarded. Others have been corroborated. We concluded that the whole lateral canthus becomes lax and drifts medially with age. Therefore, surgical correction should aim at restoring the fixation of the lateral canthus to the youthful position.
