Does a mucous reaction occur with an infectious ulcer?

• A. None
• B. Mild to severe
• C. None to mild
• D. Moderate

Answer: (B)

Mucous reaction in an infectious corneal ulcer reflects the inflammatory response of the eye and the tear film. When an infection inflames the conjunctiva and cornea, goblet cells and mucus production increase, leading to mucoid discharge or mucus in the tear film. The amount of this discharge varies with how severe the inflammation is and how virulent the infecting organism, so you can see only mild mucus in some cases or a lot of mucus in more severe infections. That variability is why the best answer is mild to severe. It would be inaccurate to say there’s no mucus at all, or to pin it to a single level like moderate, since the response can range across the spectrum depending on the infection.
