What is orbital and ocular?
Abstract. The eyes (“globes”) are housed in bilateral orbital cavities, two symmetric, pear-shaped depressions in the anterior mid-skull, with large openings anteriorly to permit vision, and small ones posteriorly for communication with the cranial cavity. Each orbit is formed by seven interconnected bones.
Where is the orbital ocular?
skull
The orbit is the bony cavity in the skull that houses the globe of the eye (eyeball), the muscles that move the eye (the extraocular muscles), the lacrimal gland, and the blood vessels and nerves required to supply these structures.
What is the function of the ocular orbit?
The orbit, which protects, supports, and maximizes the function of the eye, is shaped like a quadrilateral pyramid, with its base in plane with the orbital rim.
What is the eye orbit called?
Eye socket anatomy In addition to the globe (the eyeball), the eye socket contains blood vessels, nerves, muscles and fat. It’s made up of seven orbital bones: frontal, sphenoid, zygomatic, maxillary, lacrimal, ethmoid and palatine. Together, they form a cone-like shape that opens outward.
How do you treat orbital eye pain?
The most common treatments include:
- Home care. The best way to treat many of the conditions that cause eye pain is to allow your eyes to rest.
- Glasses. If you frequently wear contact lenses, give your corneas time to heal by wearing your glasses.
- Warm compress.
- Flushing.
- Antibiotics.
- Antihistamines.
- Eye drops.
- Corticosteroids.
Is orbit a bone?
Walls of the Orbit The orbital roof consists of two parts of two bones, the orbital plate frontal bone and the lesser wing of the sphenoid bone. The fossa of the lacrimal gland is in the orbital roof, and it lies anteriorly and laterally behind the zygomatic process of the frontal bone.
How does the orbit protect the eye?
The bony structures of the orbit (the bony cavity that contains the eyeball and its muscles, nerves, and blood vessels, as well as the structures that produce and drain tears) protrude beyond the surface of the eye. They protect the eye while allowing it to move freely in a wide arc.

What is the orbit on the face?
In anatomy, the orbit is the cavity or socket of the skull in which the eye and its appendages are situated. “Orbit” can refer to the bony socket, or it can also be used to imply the contents.
When should I see an eye doctor for eye pain?
Call 911 or your local emergency number for eye pain if: It is unusually severe or accompanied by headache, fever or unusual sensitivity to light. Your vision changes suddenly. You also experience nausea or vomiting.
