Other disorders of iris and ciliary body (H21)
Clinical Information
Glaucoma - An ocular disease, occurring in many forms, having as its primary characteristics an unstable or a sustained increase in the intraocular pressure which the eye cannot withstand without damage to its structure or impairment of its function. The consequences of the increased pressure may be manifested in a variety of symptoms, depending upon type and severity, such as excavation of the optic disk, hardness of the eyeball, corneal anesthesia, reduced visual acuity, seeing of colored halos around lights, disturbed dark adaptation, visual field defects, and headaches. (Dictionary of Visual Science, 4th ed)
Hyphema - Bleeding in the anterior chamber of the eye.
Iridocorneal Endothelial Syndrome - A grouping of three closely linked conditions: iris nevus (or Cogan-Reese) syndrome, Chandler Syndrome, and essential (progressive) iris atrophy. The most common features of this syndrome are the movement of endothelial cells off the cornea onto the iris leading to corneal swelling, distortion of the iris, and variable degrees of distortion of the pupil. The abnormal cell movement plugs fluid outflow channels of the eye causing GLAUCOMA.
Instructional Notations
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
