Abstract
The human beings are a highly species. Most of our information about the world comes to us through our eyes and most of our cultural and intellectual heritage is stored and transmitted as words and images to which our vision gives access and meaning. Knowing more about our eyes and vision is, therefore, one path to better understanding of ourselves.
The extraocular muscles are pivotal to the movement of the eye. There are 7 muscles within the orbit: 4 rectus muscles, 2-oblique muscles and the levator palpebrae superioris. Abnormalities of the extraocular muscles are rare and most accounts describe unilateral or bilateral absence of individual muscles. Numerical aberrations of extraocular muscles are commonly associated with syndromes of premature cranial bone stenosis. Although many variations of the levator palpebrae superioris muscle have been reported in fetuses. Accessory muscle slips may be associated with congenital eyelid retraction or blepharoptosis. Because of the clinical importance of the accessory levator muscle slip of the levator palpebrae superioris muscle, this study aimed to describe the morphological appearance of this variation in human adult orbits.
Keywords: Accessory levator muscle slip, blepharoptosis, extraocular muscles, eyelid retraction, levator palpebrae superioris.
