The lid may be split into anterior and posterior portions through this potential plane, which is reached by division at the gray line of the lid margin. In the upper lid, this plane is traversed by fibers of the levator aponeurosis, some of which pass through the orbicularis to attach to the skin to form the lid crease. In the lower eyelid, this plane is traversed by fibers of the orbitomalar ligament The anatomy of the lid is best approached initially by reviewing a sagittal cross section of the eyelid. The exact number of tissue layers and the relationship between the many layers are modified.. Each eyelid margin is 2 mm wide and is divided into the lacrimal portion and the ciliary portion by the lacrimal papilla. The lacrimal portion covers a one-sixth area of margin medial to the punctum while the ciliary portion covers the five-sixth part of the lid margin, lateral to the punctum

Embryology and Anatomy of the Eyelid Edward H. Bedrossian Jr. In this chapter, eyelid anatomy is discussed in a layered structural fashion. A brief discussion of the embryology and surface topography is reviewed, and the anatomy of the eyelid is then discussed—beginning with the skin anteriorly and proceeding to the conjunctiva posteriorly The hair follicle embeds in the dermis of the eyelid (which has two layers, epidermis and dermis, as opposed to the scalp which has an epidermis, dermis and a hypodermis). Eyelash follicles are 2.4 mm deep in the upper lid and 1.4 mm in the lower lid. There are more active lash follicles in the upper lid compared to the lower lid (41% vs. 15%) The eyelid can be divided into two lamellae, namely, the anterior and the posterior. The anterior lamella consists of the skin and orbicularis, while the posterior lamella is formed by tarsus and conjunctiva. The transition zone between the two lamellae at the lid margin is marked by the mucocutaneous junction called the grey line

The eyelid margins are divided by the lacrimal puncta into a medial lacrimal portion and a lateral palpebral portion. At the lid margin near the medial edge of the tarsus, the lacrimal papilla is seen as the fibrous ring surrounding the lacrimal punctum. The medial lacrimal portion is rounded and without lashes Eye Anatomy and Physiology. Under this muscle are other issues that divide the area into different planes. The skin of the eyelid which is the thinnest skin of the body covers the lids outer surface and fuses with its inner lining near the margin of the lid. There are three major parts in each eye like A well-defined mass at the lid margin is often a hordeolum or stye. A mass within the midportion of the lid is commonly a chalazion. Anatomy of orbit and eyelid with associated pathologic. Abstract.

PERTINENT SURGICAL ANATOMY. The eyelid is a complex structure that varies in its layered composition depending on the anatomic segment. The pretarsal segment extends from the lash line to the margin of the tarsal plate and is bilamellar Eyelid Margin: The eyelid margins are divided by the lacrimal puncta into a medial lacrimal portion and a lateral palpebral portion. At the lid margin near the medial edge of the tarsus, the lacrimal papilla is seen as the fibrous ring surrounding the lacrimal punctum. The medial lacrimal portion is rounded and without lashes Entropion: If you have entropion, the lower lid margin turns in towards the surface of the eye.   The eyelashes can rub against the cornea and the conjunctiva, causing irritation, foreign body sensation, infection, scarring and ulceration of the cornea. The most common treatment of entropion is corrected with surgery Lee Ann Remington OD, MS, FAAO, in Clinical Anatomy and Physiology of the Visual System (Third Edition), 2012. Puncta and Canaliculi.

The lacrimal gland is located in the lateral upper lid margin. It produces about 10 mL of secretions per day. In the process of blinking, the eyes close from the lateral edge to the medial edge, pushing the tear film across the surface of the eye Lid Margin laceration. This patient suffered multiple facial lacerations in a motor vehicle crash. Full thickness lid margin lacerations like this require special care in order to avoid notching of the lid. Lamellar tarsal sutures should be used to restore the normal anatomy of the tarsus

The eyelid glands produce the lipid layer of the tear film which prevent evaporation of tear film. Lipid secreting glands located within the superior and inferior eyelid that produces the outermost layer of the tear film on to the eyelid margin. The ducts exit the eyelid margin to deliver the lipid component of the tear film With the patient looking downward, measure the distance from the upper eyelid margin to the lid crease. The lid crease is formed by attachments of the levator aponeurosis to the overlying orbicularis and skin. In males the lid crease is normally 6-8 mm above the eyelid margin. Women have a slightly higher lid crease, normally measured at 8-10 mm
