Tear Break-up Time
Tear breakup time is the time interval between a blink and the development of a dry spot in the tear film. Less than 10 seconds is abnormal. Dry spot is visible after fluorescein staining when viewed under a slit-lamp.
Time frame: Day 0, Day 7, Day 14, Day 28, and Day 42
Conjunctival Staining
Conjunctival staining refers to the appearance of spots on the conjunctiva when dyed with lissamine green stain during an eye examination. Lissamine green temporarily stains the surface of the conjunctiva of the eye. An eye doctor looking at the eye's surface through a slit lamp observes the spots as green spots. Conjunctival staining grading scale is a 6 point scale, with 0 equals no staining (best case) and 6 equals maximum (worst) staining.
Time frame: Day 0, Day 7, Day 14, Day 28, Day 42
Corneal Staining
Corneal staining refers to the appearance of corneal abrasions when dyed with fluorescein drops during an eye examination. Fluorescein temporarily stains the surface of the cornea of the eye. An eye doctor looking at the eye's surface through a slit lamp observes the abrasions as brightly-colored spots on an otherwise smooth cornea. Corneal staining grading scale is a 15 point scale, with 0 equals no staining (best case) and 15 equals maximum (worst) staining.
Time frame: Day 0, Day 7, Day 14, Day 28, Day 42
