Ciliary body many medications against glaucoma. Its inhibition leads to the lowering of aqueous humor production and causes a subsequent drop in the intraocular pressure. There 3 main types of medication affecting the ciliary body: Ciliary body The ciliary body is a part of the eye that includes the ciliary muscle, which controls the shape of the lens, and the ciliary epithelium, which produces the aqueous humor.

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
