All the Information you Need on Photokeratitis

Photokeratitis

Key Takeaways:

  • Symptoms often begin hours after exposure and typically resolve within days.
  • Unprotected UV exposure from sun, welding, or tanning lamps triggers injury.
  • Diagnosis relies on exposure history and corneal examination using fluorescein dye.
  • Supportive care, rest, lubrication, and light avoidance form primary treatment.
  • Consistent UV-blocking eyewear significantly reduces recurrence and long-term eye damage.

Photokeratitis is a painful eye condition caused by harmful ultraviolet (UV) rays. Photokeratitis, often known as ultraviolet keratitis, can be compared to a sunburn, except that it affects the cornea instead of the skin. The cornea is the clear front part of the eyes that covers the iris, pupil, and anterior chamber. Exposure to UV rays can cause damage to the cornea and the conjunctiva.

Photokeratitis is also known with various names like arc eyes, flash burns, potato eye, bake eye, corneal flash burn, sand man’s eye, snow blindness, and keratoconjunctivitis photoelectrica.

What is Photokeratitis – “Sunburn of the Eyes”

Photokeratitis is a painful condition caused by excessive exposure to UV rays from both natural and artificial sources, like welding and tanning beds, and medical lights. The cornea (clear part of the eye) is affected, and in more severe cases, the conjunctiva can also be affected.

Recognising Photokeratitis Symptoms

Common photokeratitis symptoms include:

  • Redness and pain in the eyes.
  • Excessive tearing and/or watery eyes and gritty or sandy feeling in eyes.
  • Sensitivity to light (photophobia), blurred vision, halos around lights, and sometimes temporary loss of vision.
  • Other discomforts like swelling, eyelid twitching, headache, and general irritation.

Symptoms usually appear a few hours after UV exposure and, in most cases, improve within 24 to 48 hours.

What Causes Ultraviolet Keratitis?

Ultraviolet rays coming from the sun and other sources can affect the eyes. There are many man-made sources of ultraviolet light. Ultraviolet radiation is also emitted by various machines like lasers, lamps, mercury vapour lamps, and other welding equipment. Long term exposure to ultraviolet radiation might increase the risks of developing cataracts and macular degeneration. In addition to this, people who spend most of their time outdoors such as hikers, mountain climbers, and swimmers are more likely to get ultraviolet keratitis.

How Photokeratitis is Diagnosed?

An eye-care provider will conduct an examination of your eyes and ask about any recent exposure to UV light. In many cases, an eye-care provider will use a fluorescent dye (such as fluorescein) to stain and identify corneal abrasion or superficial corneal injury using a slit-lamp microscope.

Photokeratitis Treatment & Relief Measures

Photokeratitis treatment is generally supportive and symptom-focused because photokeratitis tends to heal naturally as the corneal surface repairs itself (usually within 24-72 hours). 

Few recommendations include:

  • Rest your eyes; stay indoors or in a dim light environment.
  • Immediately remove contact lenses, but avoid rubbing your eyes.
  • Apply cold compresses, use artificial tears for dryness and discomfort, and take over-the-counter pain relievers as needed.
  • Sometimes a doctor may prescribe an antibiotic or lubricating eye drops (like ointment) to prevent infection or support healing.

Note: If symptoms get worse – such as long-lasting pain, changes in vision or slow recovery – see a doctor right away.

How can Photokeratitis be Prevented?

There are many things that can be done to prevent this condition from happening to yourself. Preventive measures are as follows:

  • Wear eye protection like sunglasses or snow goggles while stepping out in the sun. Sunglasses block up to 99-100% of harmful UV rays.
  • Wrap-around sunglasses are also right as they block UV rays from all sides including sideways.
  • Wear a wide-brimmed hat to save your eyes and face from direct UV exposure.
  • If your job is such that you require to spend a lot of time being exposed to ultraviolet radiation, then wear proper eye protective equipment.
  • Do not stare at machines like lasers and lamps for long.
  • While using a tanning bed, make sure to wear protective eye gear, always. Try to keep your eyes closed.

Prevention – Protecting Your Eyes From UV Exposure

Prevention remains the most effective approach. Key steps:

  • Wear full-coverage sunglasses or goggles that block 99-100% of UV-A and UV-B radiation; mostly wrap-around styles or models with side protection.
  • Wear a wide-brim hat in the sun, use proper eye protection when working around very bright lights like welding arcs and tanning lamps
  • If you are working near a source of UV radiation or participating in activities in the sun, protect your eyes from damaging UV and minimize direct exposure.

Photokeratitis Follow up

Follow-up visits to the eye doctor are always recommended within 2-3 days of the initial diagnosis to ensure that the treatment is going fine. Any recurrence of pain or redness in the eyes should be promptly re-evaluated.
