The lid plate, one of the components of the eyelid, is usually composed of dense connective tissue and is located in the sagittal position between the body’s oculocutaneous muscle and the lid conjunctiva. In the vertical position, the lid plate lies beneath the levator muscle. The position of the lid plate in the sagittal position is an important protective layer of the eyelid. The lid plate has a relatively dense tissue structure and together with the skin, subcutaneous tissue, and orbicularis oculi muscle of the eyelid, it forms the complete structure of the eyelid. When the eyelid is closed, it serves to protect the eyeball. The position of the lid from a vertical position facilitates the free movement of the eyelid. When a person opens his or her eyes, the levator muscle contracts and will pull the lid plate upward together, exposing the eyeball and giving a complete field of vision to see clearly. The lid plate also serves another amazing purpose in that it helps form the heavy lids. On the surface of the lid, there is a lot of fibrous tissue that emanates straight to the skin of the eyelid, which helps form the fold of the eyelid when the eyelid is moving. This fold line in the upper lid is commonly referred to as the double eyelid (blepharoplasty). Many people who do not have double eyelids have eyelids that lack these fibrous tissues that reach into the eyelid skin. The lid also includes glandular tissue that has a secretory function that helps keep the conjunctival and corneal surfaces continuously lubricated and protective of the eye. When these glands become inflamed due to blockage, they can lead to inflammatory diseases of the lid plate such as “wheals” and “chalazia”. The lid plate plays an important role in maintaining the form and function of the eyelid. It is recommended that you drink plenty of water and eat vitamin-rich fruits and vegetables, such as carrots and apples. These foods can help protect the lid tissue.
