Medulloepithelioma of the ciliary body: ultrasonographic biomicroscopic findings.
ntraocular medulloepithelioma is an uncommon embryogenic neoplasm of neuroepithelial origin that usually develops from the nonpigmented epithelium of the ciliary body, retina, and optic nerve.1 Clinically, medulloepithelioma usually appears as a tumor of the ciliary body; only rarely does it arise in the optic nerve and retina. It frequently occurs on the ciliary body of a young child as a fles...
متن کاملCiliary body adenoma of non-pigmented epithelium.
Adenomas of the non-pigmented epithelium of the ciliary body are rare neoplasms and most of the studies are in the form of case reports. There are only 27 documented cases of acquired neoplasm of the non-pigmented ciliary epithelium (NPCE) reported in the English literature. In most reports, there was a clinical suspicion of melanoma and the diagnosis of NPCE adenoma was made on histopathologic...
متن کاملDiffuse retinal involvement in malignant nonteratoid medulloepithelioma of ciliary body in an adult.
Intraocular medulloepithelioma is a rare embryonal neoplasm that occurs predominantly in children and arises from the primitive medullary epithelium of the optic cup. Medulloepitheliomas that contain heterotopic elements or tissues such as brain, cartilage, or rhabdomyoblasts are classified as teratoid, and tumors lacking these elements are classified as nonteratoid medulloepitheliomas. Both no...
متن کاملIsolation of non-pigmented epithelial cells from rabbit ciliary body.
We describe a new technique for the separation and isolation of nonpigmented ciliary body epithelial cells from rabbit. Excised ciliary body is incubated in a medium buffered with EGTA to a free-Ca2+ concentration of 10(-8) M, and the nonpigmented cell layer is separated from the pigmented layer by microdissection under direct visualization. This technique yields intact cells which are greater ...
متن کاملA Model of the Respiratory System in the Newborn Infant
A dynamic mathematical model is presented which successfully simulates the respiratory control system of the newborn infant in different physiological conditions. The primary objective in constructing this model has been to provide a simulation aid in the investigation of maturation of the respiratory system, and the respiratory disorders during the newborn period, without the need for invasive...
