The eyes become red, watery, and sensitive to light, and vision may decrease somewhat.
How long does it take to recover from superficial punctate keratitis?
Almost everyone who has this disorder recovers completely. When the cause is a virus (other than a herpes simplex eye infection or herpes zoster of the eye [shingles]), no treatment is needed, and recovery usually occurs within 3 weeks.
What kind of light can cause keratitis in the cornea?
UVB light (wavelength < 300 nm) can burn the cornea, causing keratitis or keratoconjunctivitis. Arc welding is a common cause; even a brief, unprotected glance at a welding arc may result in a burn. Other causes include high-voltage electric sparks, artificial sun lamps, and sunlight reflected off snow at high altitudes.
How is keratoconjunctivitis sicca and blepharitis treated?
Blepharitis, keratoconjunctivitis sicca, and trachoma require specific therapy.
