What is the grading for lid parallel conjunctival folds (LIPCOF) if there are more than two permanent and clear parallel folds, (normally higher than 0.2 mm) or more than two permanent and clear parallel folds plus disrupted micro-folds above?

• A. 0
• B. 2
• C. 1
• D. 3

Answer: (D)

LIPCOF grading measures how lid-parallel conjunctival folds reflect lid–lens interaction and mechanical irritation. The severity rises with more visible, well-formed folds, and with disruption of micro-folds. If there are more than two permanent and clear parallel folds, typically larger than about 0.2 mm, that already signals a significant level of irritation. When this is accompanied by disrupted micro-folds, the irritation is even more pronounced. This combination corresponds to the most severe category on the LIPCOF scale, indicating substantial lid-induced conjunctival change and a higher likelihood of discomfort or poor lens tolerance.
