What is the anterior uvea?

What is the anterior uvea?

Anterior uveitis is an inflammation of the middle layer of the eye. This middle layer includes the iris (colored part of the eye) and adjacent tissue, known as the ciliary body.

What is the posterior uvea?

Posterior uveitis is inflammation of the uvea due to the body’s response to various factors such as microorganisms, toxins and damaged tissue. Inflammation may cause redness, swelling and heat in a particular area of the eye.

Why is it called uvea?

The middle coat of the eye is called the uvea (from the Latin for “grape”) because the eye looks like a reddish-blue grape when the outer coat has been dissected away.

What is uvea made of?

The uvea is the middle layer of the eye. It lies beneath the white part of the eye (the sclera). It is made of the iris, ciliary body, and choroid.

What does the uvea consist of?

The uvea consists of the layer and structures of the eye beneath the white of the eye (sclera).

What does uvea consist of?

The uvea has 3 main parts: (1) the choroid (the tissue layer filled with blood vessels); (2) the ciliary body (the ring of tissue that contains muscles that change the shape of the lens and makes the clear fluid that fills the space between the cornea and the iris; and (3) the iris (the colored part of the eye).

Is uvea in the anterior segment?

The uveal tract is the middle layer of the eye, divided into the anterior uvea (iris, ciliary body) and posterior uvea (choroid). The uvea is sandwiched between an outer layer (sclera) and an inner layer (retina). The anterior segment is separated from the posterior segment by the lens.

What is the most anterior portion of the uvea?

The most anterior portion of the uvea is the iris. The anterior pigmented portion of the retina is called the ora serrata. The sclera is the “white of the eye”.

Is the tibialis anterior overactive or underactive?

Tibialis anterior is one of the muscles that tend to be inhibited and underactive this leads to overactive of synergistic muscles; extensor hallicus longus, extensor digitorium longus and peroneous tertius.

What does the tibialis anterior cover?

Tibialis anterior muscle lies medial to extensor digitorum longus and extensor hallucis longus, which makes it the most medial muscle in the anterior compartment of the leg. It also covers the anterior tibial vessels and deep fibular nerve in the proximal part of the leg.

What does the anterior uvea consist of?

Anterior Uvea. The anterior uvea consists of the iris, ciliary body, and anterior chamber (or iridocorneal) angle. The iris provides most of the eye color as well as an aperture (pupil) to regulate the amount of light that enters the eye and posterior segment.

What is the path of the tibialis posterior?

The two parts become one muscle, which travels towards the foot. At the ankle, the tendon of tibialis posterior passes posteriorly to the medial malleolus of the tibia. It continues into the medial part of the foot by passing through the tarsal tunnel, deep to the flexor retinaculum of ankle.
