What is periorbital tissue?
Periorbital edema is a term for swelling around the eyes. The area around the eyes is called the eye socket or eye orbit. Sometimes people refer to this condition as periorbital puffiness or puffy eyes. You can have periorbital edema in just one eye or both at the same time.
Where is the periorbital area of the eye?
The well-known anatomical classification divides the face into: upper face, mid face and lower face. At the boundary between upper and mid face is the periorbital area which also contains three zones (Figure 1).
What causes periorbital swelling?
Periorbital puffiness, also known as puffy eyes, or swelling around the eyes, is the appearance of swelling in the tissues around the eyes, called the orbits. It is almost exclusively caused by fluid buildup around the eyes, or periorbital edema.
What are the periorbital structures?
BRANCHES Lacrimal: lacrimal gland, conjunctiva, and skin of the upper eyelid. Frontal: emits the main branches to the eyelid, forehead, and scalp. Supraorbital: forehead, scalp, upper eyelid, and frontal sinus. Supratrochlear: Forehead and upper eyelid.
What is periorbital 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.
What is the difference between periorbital and periocular?
Periocular dermatitis, also known as periorbital dermatitis, is a common dermatological disorder characterized by inflammation of the eyelids and the skin surrounding the eyes.
What causes periorbital?
Periorbital cellulitis is an infection of your eyelid or the skin around your eyes. Adults can get it, but children under 2 are most likely to have it. It happens when bacteria attack the soft tissue around your eye, including your eyelid.
What is the skin under your eye called?
The skin underneath your eyes, sometimes known as your “tear trough,” is thinner and more sensitive than other skin. As you grow older, this skin can become more translucent, making the veins underneath more visible.
What is a periorbital infection?

What cells are found in the periosteum?
Periosteum and endosteum contain cells (osteoblasts, osteoclasts, and osteoprogenitor cells) required for bone development and remodeling of the bone.
What is the difference between periocular and periorbital?

What is the fat under your eyes called?
Bags under the eyes, also called eye bags, form when weakened and sagging skin relaxes and creates a pouch. The fat pads under the eyes then slip down to fill the space, giving the appearance of a “bag.” Excess fluid in the body can also pool in this area, making the lower eyelids look even more puffy and swollen.

What is periorbital ecchymosis?
Periorbital ecchymosis (raccoon eye or panda sign) is a common clinical sign of skull base injury resulting from accidental injuries. Spontaneous periorbital ecchymosis harbingers a variety of medical disorders. An urgent clinical evaluation is compulsory, which unfolds the underlying disease.
What tissue is the periosteum made of?
Periosteum layers It’s made of thick collagen fibers. Most of the periosteum’s blood vessels and nerves are in the outer layer. The inner layer (sometimes called the cambium layer) contains the osteoprogenitor cells and the osteoblasts they create when your bone is growing or needs to heal.
