ICD-10: H18.011

Clinical Description of ICD-10 Code H18.011

ICD-10 Code H18.011 refers specifically to anterior corneal pigmentations in the right eye. This condition is categorized under the broader classification of disorders affecting the cornea, which is the transparent front part of the eye that covers the iris, pupil, and anterior chamber. The cornea plays a crucial role in focusing vision, and any abnormalities can significantly impact visual acuity.

Definition and Characteristics

Anterior corneal pigmentations are deposits of pigment that occur on the surface of the cornea. These pigmentations can arise from various causes, including:

• Genetic Factors: Some individuals may have a hereditary predisposition to develop corneal pigmentations.
• Environmental Factors: Prolonged exposure to ultraviolet (UV) light can lead to changes in the corneal epithelium, resulting in pigmentation.
• Pathological Conditions: Certain diseases, such as Wilson's disease or other metabolic disorders, can lead to abnormal pigment deposition in the cornea.

The pigmentations can vary in appearance, ranging from small, discrete spots to larger, more diffuse areas. Clinically, they may be asymptomatic or associated with visual disturbances, depending on their size and location.

Symptoms

Patients with anterior corneal pigmentations may experience:

• Visual Disturbances: Depending on the extent and location of the pigmentations, patients may report blurred vision or other visual impairments.
• Discomfort: Some individuals may experience irritation or discomfort, particularly if the pigmentations affect the corneal surface.
