ICD-10: H18.442

Keratomalacia, classified under ICD-10-CM code H18.442, refers to a severe corneal condition characterized by the softening and ulceration of the cornea, specifically in the left eye. This condition is primarily associated with vitamin A deficiency, which is crucial for maintaining the health of epithelial tissues, including those in the eyes.

Clinical Description

Definition

Keratomalacia is a progressive condition that leads to the degeneration of the corneal tissue. It typically manifests as a result of inadequate vitamin A levels, which can be due to malnutrition, certain medical conditions, or malabsorption syndromes. The left eye designation in the ICD-10 code H18.442 indicates that the condition is localized to that eye.

Symptoms

Patients with keratomalacia may experience a range of symptoms, including:
- Visual Disturbances: Blurred vision or loss of vision due to corneal opacity.
- Eye Discomfort: Pain or a sensation of grittiness in the affected eye.
- Photophobia: Increased sensitivity to light.
- Tearing: Excessive tearing or discharge from the eye.
- Corneal Ulceration: Visible ulceration or softening of the cornea upon examination.

Pathophysiology

The underlying mechanism involves the degradation of corneal epithelial cells, leading to the formation of a soft, necrotic area in the cornea. This can result in complications such as corneal perforation, which may necessitate surgical intervention, including corneal transplantation.

Diagnosis

Diagnosis of keratomalacia typically involves:
- Clinical Examination: An ophthalmologist will perform a thorough eye examination, often using a slit lamp to assess the cornea's condition.
- History and Symptoms: A detailed patient history focusing on dietary habits, systemic diseases, and symptoms is crucial.
- Nutritional Assessment: Evaluating vitamin A levels may be necessary, especially in cases where malnutrition is suspected.

Treatment

The management of keratomalacia focuses on addressing the underlying vitamin A deficiency and may include:
- Vitamin A Supplementation: Administering vitamin A orally or through intramuscular injections to restore adequate levels.
- Topical Treatments: Using lubricating eye drops or ointments to alleviate discomfort and protect the cornea.
- Surgical Intervention: In severe cases, surgical options such as corneal grafting may be required to restore vision and corneal integrity.

Prognosis

The prognosis for keratomalacia largely depends on the timeliness of diagnosis and treatment. Early intervention can lead to significant improvement in symptoms and visual outcomes, while delayed treatment may result in permanent vision loss or complications.

In summary, ICD-10 code H18.442 for keratomalacia of the left eye highlights a critical condition that necessitates prompt medical attention to prevent serious ocular complications.
