ICD-10: H18.443

Keratomalacia, classified under ICD-10 code H18.443, refers to a severe corneal condition characterized by the softening and degeneration of the cornea, typically due to vitamin A deficiency. This condition can lead to significant visual impairment and is often associated with other ocular complications.

Clinical Description of Keratomalacia

Definition and Pathophysiology

Keratomalacia is primarily a result of a deficiency in vitamin A, which is crucial for maintaining the health of epithelial tissues, including those in the cornea. The lack of vitamin A leads to the breakdown of the corneal epithelium, resulting in softening and ulceration of the cornea. This condition can progress rapidly, especially in cases where the deficiency is severe or prolonged.

Symptoms

Patients with bilateral keratomalacia may present with a variety of symptoms, including:
- Visual Disturbances: Blurred vision or loss of vision due to corneal opacity.
- Eye Discomfort: Patients may experience pain, redness, or a sensation of grittiness in the eyes.
- Photophobia: Increased sensitivity to light.
- Tearing: Excessive tearing or discharge from the eyes.

Risk Factors

The primary risk factor for keratomalacia is a deficiency in vitamin A, which can occur due to:
- Malnutrition, particularly in populations with limited access to vitamin A-rich foods.
- Malabsorption syndromes that affect nutrient uptake.
- Certain medical conditions that increase the body's demand for vitamin A.

Diagnosis

Diagnosis of keratomalacia typically involves:
- Clinical Examination: An ophthalmologist will perform a thorough eye examination, looking for signs of corneal softening, opacification, and other related ocular changes.
- History and Symptoms: A detailed patient history regarding dietary habits and any symptoms of visual impairment will be taken into account.
- Nutritional Assessment: Evaluating the patient's nutritional status to identify potential vitamin A deficiency.

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 in the body.
- Ocular Treatments: In some cases, topical treatments or surgical interventions may be necessary to manage corneal damage or restore vision.
- Nutritional Counseling: Educating patients about dietary sources of vitamin A, such as liver, fish, dairy products, and leafy green vegetables.

Prognosis

The prognosis for patients with keratomalacia largely depends on the timeliness of diagnosis and treatment. Early intervention can lead to significant improvement in symptoms and visual outcomes. However, if left untreated, keratomalacia can result in permanent corneal damage and vision loss.
