H15-H22: Disorders of sclera, cornea, iris and ciliary body
H18: Other disorders of cornea
The ICD-10 code, H18, refers to a group of conditions known as 'Other disorders of the cornea'. The cornea is the clear, dome-shaped front part of the eye. It helps focus light that enters the eye. Diseases and conditions under this group disrupt the health or function of the cornea, leading to potential vision problems. Symptoms may include eye redness, pain, blurriness, light sensitivity, or feeling like something is in your eye. These conditions can arise due to a variety of causes, including infections, injuries, genetic disorders, or age-related changes. Disease progression may vary among conditions, with some causing temporary discomfort, while others potentially leading to permanent vision loss. The primary system affected by these disorders is the visual system but can indirectly weaken other body functions due to impaired vision.
