Dystrophic processes in the choroid can have a hereditary nature or a secondary nature, for example, be a consequence of the transferred inflammatory processes.
Iridocyclitis is an inflammatory disease of the iris and ciliary body. The inflammatory process in the anterior part of the vasculature can begin with the iris (iritis) or the ciliary body (cyclite).
At the earliest stages of development of the visual organ, malformations of the iris may form, caused by non-closure of the anterior end of the optic cup slit, which manifests itself as a defect of the iris - congenital coloboma of the iris.
Congenital aniridia is the absence of iris. With a thorough examination, sometimes find small fragments of the root, iris. This pathology can be combined with other malformations - microphthalmia, subluxation of the lens, nystagmus.
