Uveitis Uveitis Uveitis is the inflammation of the uvea, the pigmented layer that lies between the inner retina and the outer fibrous layer composed of the sclera and cornea. The uvea consists of the middle layer of pigmented vascular structures of the eye and includes the iris, ciliary body, and choroid. Uveitis is an ophthalmic emergency and requires a thorough examination by an optometrist or ophthalmologist and urgent treatment to control the inflammation. It is often associated with other ocular problems. Uveitis is classified anatomically into anterior, intermediate, posterior, and panuveitic forms—based on the part of the eye primarily affected.

Iris cyst a shadow with a tumor but almost never with a cyst. Ultrasound B-scan (USB) uses wavelengths of 10-20MHz to form an image of the eye. USB can be used to identify the extension of the iris cyst in either the anterior or posterior chamber. It can also be used to identify midzonal cysts behind the iris and to determine whether there is ciliary body involvement. The preferred method to determine ciliary body involvement however, is not USB but ultrasound biomicroscopy. Ultrasound biomicroscopy, (UBM) has a higher resolution than USB an di t also using soundwaves with a higher frequency from
