H15-H22: Disorders of sclera, cornea, iris and ciliary body

H17: Corneal scars and opacities

Corneal scars and opacities refer to a group of conditions characterized by the appearance of cloudy or opaque areas on the cornea, the clear surface of the eye. These conditions are typically the result of damage to the cornea due to injury, infection, or inflammation. Symptoms commonly include decreased or blurry vision, eye pain, and sensitivity to light. In severe cases, these conditions can lead to significant loss of vision. Progression may vary, but generally, corneal scars and opacities persist as long as the underlying cause isn't addressed. The affected system is primarily the ocular system, particularly the cornea. A diverse set of factors can lead to these conditions, ranging from physical trauma and chemical burns to microbial infections and certain inherited disorders.
