ICD-10: H16.142

Punctate keratitis, specifically coded as H16.142 in the ICD-10 classification, refers to a condition characterized by the presence of small, pinpoint lesions on the cornea of the left eye. This condition is often associated with various underlying causes, including infections, dry eye syndrome, or exposure to irritants. Below is a detailed overview of punctate keratitis, its clinical description, symptoms, diagnosis, and treatment options.

Clinical Description

Definition

Punctate keratitis is an inflammatory condition of the cornea, where small, discrete spots of epithelial damage occur. These spots can be seen as punctate opacities on the corneal surface, which may be due to various etiologies, including viral infections (such as herpes simplex), bacterial infections, or environmental factors.

Etiology

The causes of punctate keratitis can vary widely and may include:
- Infectious agents: Viral (e.g., herpes simplex virus), bacterial, or fungal infections.
- Non-infectious factors: Dry eye syndrome, exposure to chemicals, or environmental irritants.
- Systemic diseases: Conditions like Sjögren's syndrome or autoimmune disorders can also contribute to the development of punctate keratitis.

Symptoms

Patients with punctate keratitis may experience a range of symptoms, including:
- Eye discomfort: This can manifest as a gritty or burning sensation.
- Redness: The affected eye may appear red due to inflammation.
- Photophobia: Increased sensitivity to light is common.
- Tearing: Patients may experience excessive tearing or watery eyes.
- Blurred vision: Depending on the severity of the lesions, vision may be affected.

Diagnosis

The diagnosis of punctate keratitis typically involves:
- Patient history: A thorough history to identify potential causes, including recent infections or exposure to irritants.
- Ophthalmic examination: A slit-lamp examination is crucial for visualizing the cornea and identifying the characteristic punctate lesions.
- Additional tests: In some cases, cultures or scrapings may be taken to identify infectious agents.

Treatment

Treatment for punctate keratitis focuses on addressing the underlying cause and alleviating symptoms. Common approaches include:
- Topical medications: Antibiotic or antiviral eye drops may be prescribed if an infection is present.
- Lubricating eye drops: Artificial tears can help relieve dryness and discomfort.
