ICD-10: H16.139

Photokeratitis, classified under ICD-10 code H16.139, refers to a condition characterized by inflammation of the cornea due to exposure to ultraviolet (UV) light. This condition is often likened to a sunburn of the eye and can occur after exposure to intense sunlight, particularly in environments with reflective surfaces such as snow, water, or sand.

Clinical Description

Definition

Photokeratitis is an acute condition resulting from the overexposure of the corneal epithelium to UV radiation. It is not limited to any specific eye and is categorized as "unspecified" when the affected eye is not identified or when the condition is not further classified.

Symptoms

Patients with photokeratitis typically present with a range of symptoms, which may include:
- Pain and discomfort: Often described as a gritty or burning sensation in the eyes.
- Redness: The eyes may appear red and inflamed.
- Tearing: Increased tear production is common as the eyes attempt to wash away irritants.
- Photophobia: Sensitivity to light can make it difficult for patients to be in well-lit environments.
- Blurred vision: Temporary visual disturbances may occur due to corneal swelling or damage.

Diagnosis

Diagnosis of photokeratitis is primarily clinical, based on the patient's history of UV exposure and the presentation of symptoms. An eye examination may reveal:
- Corneal edema: Swelling of the cornea.
- Epithelial defects: Damage to the surface layer of the cornea, which can be observed using a fluorescein stain.

Treatment

Management of photokeratitis typically involves:
- Symptomatic relief: This may include the use of artificial tears, topical anesthetics, and anti-inflammatory medications to alleviate pain and discomfort.
- Avoidance of further UV exposure: Patients are advised to stay indoors or wear protective eyewear until symptoms resolve.
- Follow-up care: Monitoring for any complications, such as secondary infections or persistent corneal damage, is essential.

Epidemiology

Photokeratitis is more prevalent in certain populations, particularly those who spend extended periods outdoors without adequate eye protection. It is also more common in regions with high UV exposure, such as near the equator or at high altitudes.

Conclusion

ICD-10 code H16.139 serves as a critical identifier for photokeratitis, unspecified eye, facilitating accurate diagnosis and treatment. Awareness of this condition is essential, especially for individuals at risk of UV exposure, to prevent potential complications and ensure timely intervention.
