Muscular layer of the eye: mainly orbicularis oculi muscle, which belongs to skeletal muscle and is arranged in the form of annular eyelid fissure. The part near the eyelashes is called the ciliary part of orbicularis oculi muscle, also called Riolland muscle. The orbicularis oculi muscle is dominated by the facial nerve, and the eyelid splits and closes. There are levator palpebrae superioris and its aponeurosis scattered between orbicularis oculi muscle and meibomian, which are dominated by oculomotor nerve and can lift the eyelid.
