ICD-10: H16.133

Photokeratitis, classified under ICD-10 code H16.133, is 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 UV light sources, such as sunlight, welding arcs, or tanning beds. Below is a detailed clinical description and relevant information regarding this diagnosis.

Clinical Description

Definition

Photokeratitis is an acute, painful condition resulting from damage to the corneal epithelium caused by UV radiation. The bilateral designation (H16.133) indicates that both eyes are affected, which is common in cases of photokeratitis due to simultaneous exposure to UV light.

Symptoms

Patients with photokeratitis typically present with a range of symptoms, including:
- Severe eye pain: Often described as a burning or gritty sensation.
- Redness of the eyes: Due to inflammation and irritation.
- Tearing: Increased production of tears as a protective response.
- Sensitivity to light (photophobia): Discomfort in bright environments.
- Blurred vision: Temporary visual disturbances may occur.
- Swelling of the eyelids: In some cases, the eyelids may become swollen.

Causes

The primary cause of photokeratitis is exposure to UV light, which can occur in various settings:
- Natural sunlight: Particularly at high altitudes or during summer months.
