Question:
What is punctate keratitis?

Answer:
Superficial punctate keratitis (SPK) is the characteristic finding in Thygeson's Disease where the upper layers of the cornea are inflamed. An ophthalmologist may note small white opacities just below the surface of the cornea with a characteristic "negative fluorescein staining" pattern. Common symptoms include recurrent burning, tearing, light sensitivity, and a sensation of a foreign body in their eyes. Sometimes these symptoms can be quite severe despite having few signs on a slit lamp exam. The symptoms tend to be self-limited, although a mild topical steroid can be used if the presentation is severe.
