What are lower lid retractors?

Lower lid retractors The lower eyelid retractor is a fascial extension from the terminal muscle fibers and tendon of the inferior rectus muscle, originating as the capsulopalpebral head. … The orbital septum fuses with the capsulopalpebral fascia approximately 5 mm below the inferior tarsal border.

What is the orbital septum?

The orbital septum is a fibrous membrane that extends from the periosteum of the orbit as the arcus marginalis and lies just deep to the orbicularis oculi muscle. In the upper lids, the septum fuses with the levator aponeurosis.

What is the orbital fascia?

The periorbita, also called the orbital periosteum or orbital fascia, covers the bones of the orbit (Figure 8-17). This dense connective tissue membrane serves as an attachment site for muscles, tendons, and ligaments and is a support structure for the blood supply to the orbital bones.

How does orbital cellulitis differ from periorbital cellulitis?

Periorbital cellulitis is an infection of the eyelid and area around the eye; orbital cellulitis is an infection of the eyeball and tissues around it.

What does orbital septum separate?

The orbital septum separates the intra-orbital fat from eyelid fat and orbicularis oculi muscle, and also provides a barrier against spread of infection between the preseptal space to postseptal space (orbit proper) 1.

How common are Epicanthal folds?

Epicanthal folds are the folds of skin that run from the upper eyelid to the inner corner of the eye. In some people, they cover this inner corner. This is completely normal in many people, including those of Asian descent and infants. But in some cases, they may be a sign of an underlying medical condition.

It is made up of the midfoot (cuboid, medial, intermediate, and lateral cuneiform, and navicular) and hindfoot (talus and calcaneus).

What is the inferior tarsus?

There are two plates; the superior tarsus (upper eyelid) and inferior tarsus (lower eyelid). They act to form the scaffolding of the eyelid, and are composed of dense connective tissue. The superior tarsus also acts as the attachment site of the levator palpebrae superioris.
