H21: Other disorders of iris and ciliary body

The group of conditions classified as "Other disorders of iris and ciliary body" primarily affect the colored portion of the eye (iris) and the ciliary body, which is a part of the eye involved in the production of the aqueous humor and control of the eye's lens shape. These disorders can be a result of genetic factors, injury, or other underlying health issues like uveitis — inflammation within the eye. Common symptoms can include change in eye color, light sensitivity, blurry vision, and discomfort or pain in the eye. Over time, these conditions might progress to more severe vision problems if left unaddressed. Notably, these disorders do not directly transmit from person to person, but some, like pigment dispersion syndrome, might have a genetic component. Therefore, it's possible for such problems to occur within members of the same family.
