Palpebral conjunctiva Marginal conjunctiva extends from the lid margin to about 2 mm on the back of lid up to a shallow groove, the sulcus subtarsalis. Tarsal conjunctiva is firmly adherent to the whole tarsal plate in the upper lid. In the lower lid, it is adherent only to half width of the tarsus. Orbital part of palpebral conjunctiva lies loose between the tarsal plate and fornix. Bulbar conjunctiva Lies loose over the underlying structures and thus can be moved easily. It is separated from the anterior sclera by episcleral tissue and Tenon's capsule. A 3‐mm ridge of bulbar conjunctiva around the cornea is called limbal conjunctiva. In the area of limbus, the conjunctiva, Tenon's capsule and the episcleral tissue are fused into a dense tissue which is strongly adherent to the underlying corneoscleral junction. At the limbus, the epithelium of conjunctiva becomes continuous with that of cornea Forniceal Conjunctiva: Joins the

The middle 5 mm has 5 layers: skin, orbicularis, levator aponeurosis, tarsus, and conjunctiva. Above 10 mm, the upper eyelid has 7 layers: skin, orbicularis, septum, preaponeurotic fat, levator aponeurosis, Mu¨ller’s muscle, and conjunctiva.

ANATOMY AND PHYSIOLOGY 39 Vasculature: upper lid supplied by the marginal and peripheral vascular arcades. The lower lid usually has only a peripheral arcade. The peripheral vascular arcade lies along the peripheral border of the tarsus between the lid retractors and Mu¨ller’s (inferior tarsal) muscle. The marginal arcade lies anterior to the tarsus 2 mm above the eyelid margin. In eyelid surgery, visualizing these horizontally running vessels indicates that you are below the level of the aponeurosis. ORBITAL CONNECTIVE AND SUPPORTING TISSUES Most of the orbit is ﬁlled with fat. Fat pads: removal of too much fat during surgery may result in sunken orbits, EOM restriction, and cicatricial eyelid changes. Upper lid: two fat pads.
