H16.133 Photokeratitis, bilateral

Name of the Condition

• Photokeratitis, bilateral

Summary

Photokeratitis is a painful eye condition caused by exposure to ultraviolet (UV) radiation, resulting in inflammation of the cornea. It is often described as a sunburn of the eye and can affect one or both eyes.

Causes

Exposure to UV light, typically from the sun or artificial sources such as welding arcs, tanning beds, or certain types of lamps, is the primary cause. Reflective surfaces like snow, water, or sand can amplify UV exposure.

Risk Factors

• Outdoor activities without proper eye protection.
• Participation in activities like skiing, welding, or using tanning equipment.
• High-altitude environments or locations near the equator where UV exposure is stronger.

Symptoms

• Eye pain and redness.
• Sensitivity to light (photophobia).
• A gritty sensation in the eye.
• Blurred vision and tearing.

Diagnosis

Diagnosis involves a clinical examination by an eye care professional, often using a slit lamp to assess corneal damage. Fluorescein staining may be used to detect epithelial defects.

Treatment Options

• Temporary avoidance of UV exposure to allow healing.
• Use of lubricating eye drops or artificial tears to relieve discomfort.
• Pain relievers, such as oral NSAIDs or topical anesthetics, under medical guidance.
• Cold compresses to reduce inflammation.

Prognosis and Follow-Up

Most cases resolve within 24 to 48 hours with proper care. Follow-up may be recommended to ensure complete healing and to rule out complications. Severe or persistent symptoms should be evaluated by a healthcare provider.

Complications

Rarely, photokeratitis can lead to corneal scarring, infection, or temporary vision loss if left untreated. Chronic exposure may increase the risk of long-term eye damage.

Lifestyle & Prevention

• Wear UV-protective sunglasses or goggles when outdoors, especially in bright conditions.
• Use protective eyewear during activities with artificial UV sources, such as welding.
• Avoid prolonged exposure to reflective surfaces like snow or water without eye protection.

When to Seek Professional Help

Seek medical attention if symptoms worsen, persist beyond 48 hours, or if there is severe pain, vision changes, or signs of infection (e.g., discharge, increased redness).

Tips for Medical Coders

Document the bilateral nature of the condition clearly in the medical record. Ensure the diagnosis is supported by clinical findings and patient history, as bilateral photokeratitis requires specific coding to reflect both eyes being affected.
