Actinic conjunctivitis

Actinic Conjunctivitis is a type of eye disease that is primarily caused by prolonged exposure to ultraviolet (UV) radiation. It is also known as UV keratoconjunctivitis or photokeratitis.

Causes

The main cause of Actinic Conjunctivitis is prolonged exposure to UV radiation. This can occur from natural sources such as sunlight, or from artificial sources such as welding arcs or tanning beds. Other factors that can increase the risk of developing Actinic Conjunctivitis include high altitude, snow, water, and white sand, which can reflect UV radiation and intensify exposure.

Symptoms

The symptoms of Actinic Conjunctivitis typically appear within a few hours after exposure to UV radiation. They can include:

• Redness of the eyes
• Pain in the eyes
• A feeling of grittiness in the eyes
• Blurred vision
• Sensitivity to light (photophobia)
• Tearing or discharge from the eyes

Diagnosis

The diagnosis of Actinic Conjunctivitis is usually based on the patient's history of UV exposure and the presence of typical symptoms. An eye examination may reveal a roughened corneal surface and conjunctival redness. In some cases, a special dye called fluorescein may be used to highlight areas of damage on the cornea.

Treatment

The treatment of Actinic Conjunctivitis primarily involves relieving symptoms and preventing further damage to the eyes. This can include:

• Avoiding further exposure to UV radiation
• Using lubricating eye drops or ointments
• Wearing sunglasses to protect the eyes from light
• In severe cases, using topical steroids or nonsteroidal anti-inflammatory drugs (NSAIDs)

Prevention

Prevention of Actinic Conjunctivitis involves protecting the eyes from UV radiation. This can be achieved by wearing sunglasses that block UV rays, using a wide-brimmed hat to shield the eyes from the sun, and avoiding exposure to UV radiation from artificial sources.
