Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'кератит' (same meaning, direct cognate). The main trap is confusing it with 'конъюнктивит' (conjunctivitis). Ensure the correct anatomical part (cornea vs. conjunctiva) is specified.
Common Mistakes
- Mispronouncing it as /kɛrætɪs/ (stress error).
- Using it interchangeably with 'conjunctivitis'.
- Spelling as 'kerratitis' or 'kerititis'.

FAQ
Frequently Asked Questions
It depends on the cause. Infectious keratitis (bacterial, viral) can be contagious, while keratitis from injury or autoimmune disease is not.
Common symptoms include eye redness, pain, blurred vision, sensitivity to light (photophobia), excessive tearing, and a feeling of something in the eye.
In severe cases, especially if untreated, keratitis can lead to corneal scarring, ulceration, and permanent vision loss or blindness.
'Pink eye' typically refers to conjunctivitis, which is inflammation of the clear tissue covering the white of the eye and lining the eyelid. Keratitis is inflammation of the cornea, the clear dome at the front of the eye, and is often more painful and vision-threatening.
