To confirm the changes in the upper eyelid structure during normal movements such as opening and closing we observed the changes with magnetic resonance imaging and obtained the following results. (1) In the anterior lobe of the upper eyelid, the lower part moves more than the upper part. (2) The tarsus slides toward posterior and upper direction when the eye opens. (3) The orbital septum and the orbital fat move posteriorly and thicken when the eye opens. (4) When the eye opens Whitnall's ligament moves posteriorly with a little change of the acting vector direction of the levator muscle. (5) Aponeurosis of the levator muscle clearly separates from Müller's muscle when the eye opens. (6) We suspected that there is some suspending tissue of Whitnall's ligament that consists of a membranous or mesh-like structure in the orbital fat above the levator muscle.

D008279	Magnetic Resonance Imaging	Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.

D009068	Movement	The act, process, or result of passing from one place or position to another. It differs from LOCOMOTION in that locomotion is restricted to the passing of the whole body from one place to another, while movement encompasses both locomotion but also a change of the position of the whole body or any of its parts. Movement may be used with reference to humans, vertebrate and invertebrate animals, and microorganisms. Differentiate also from MOTOR ACTIVITY, movement associated with behavior.	Movements
D009801	Oculomotor Muscles	The muscles that move the eye. Included in this group are the medial rectus, lateral rectus, superior rectus, inferior rectus, inferior oblique, superior oblique, musculus orbitalis, and levator palpebrae superioris.
