Actinic conjunctivitis causes redness and swelling of the eyes.

Actinic conjunctivitis is an inflammation of the conjunctiva due to exposure to ultraviolet (UV) light. This condition is often associated with prolonged exposure to sunlight or artificial sources of UV radiation, such as welding arcs.

Pathophysiology

The conjunctiva is a thin, transparent tissue that covers the white part of the eye and lines the inside of the eyelids. When exposed to UV light, the conjunctiva can become inflamed, leading to symptoms such as redness, swelling, and discomfort. The inflammation is a result of the body's immune response to the damage caused by UV radiation.

Symptoms

Common symptoms of actinic conjunctivitis include:

• Redness of the eyes
• Swelling of the conjunctiva and surrounding tissues
• Sensation of grittiness or irritation
• Increased tearing or watery eyes
• Sensitivity to light (photophobia)
• Possible grayness around the eyes

Causes

Actinic conjunctivitis is primarily caused by exposure to UV light. Sources of UV exposure include:

• Direct sunlight, especially during peak hours
• Reflection of sunlight from surfaces such as water, sand, or snow
• Artificial sources of UV light, such as tanning beds and welding arcs

Diagnosis

Diagnosis of actinic conjunctivitis is typically based on the patient's history of UV exposure and the clinical presentation of symptoms. An ophthalmologist or optometrist may perform a thorough eye examination to rule out other causes of conjunctivitis.

Treatment

Treatment for actinic conjunctivitis focuses on relieving symptoms and preventing further UV exposure. Recommended measures include:

• Avoiding further exposure to UV light
• Wearing protective eyewear, such as sunglasses with UV protection
• Using artificial tears or lubricating eye drops to alleviate discomfort
• Applying cold compresses to reduce swelling

Prevention

Preventive measures are crucial in avoiding actinic conjunctivitis. These include:

• Wearing sunglasses that block 100% of UV rays
• Using wide-brimmed hats to shield the eyes from direct sunlight
• Avoiding tanning beds and using protective gear when welding
