This study evaluated the ocular surface tolerability of the prostaglandin analogues bimatoprost ophthalmic solution 0.01% (Lumigan® 0.01%), travoprost ophthalmic solution 0.004% (Travatan Z®) and latanoprost ophthalmic solution 0.005% (Xalatan®) in patients previously treated with Xalatan® who have open-angle glaucoma or ocular hypertension.

Mean Conjunctival Hyperemia at Week 12
Conjunctival hyperemia was analyzed using the average of the scores of both eyes. Hyperemia is engorgement of the blood vessels (redness) of the bulbar conjunctiva of the eye (the clear membrane covering the white surface of the eye). Hyperemia was graded on a 5 point scale where 0=none (normal), 0.5=trace (trace flush reddish pink), 1=Mild (mild flush reddish color), 2=Moderate (bright red color) and 3=severe (deep bright diffuse redness).
Time frame: Week 12
Mean Corneal Staining With Fluorescein at Week 12
Corneal staining was analyzed using the average of the scores of both eyes. The cornea is the transparent front part of the eye which covers the iris and pupil. To detect the presence or absence of corneal puncta (tiny disruptions in the surface of the eye), fluorescein dye is administered into the eye and the eye is graded using a 5-point scale where 0=None (no puncta), 0.5=Trace (1-5 puncta), 1=Mild (6-20 puncta), 2=Moderate (\>20 puncta) and 3=Severe (too many puncta to count).
Time frame: Week 12
Mean Tear Break Up Time (TBUT) at Week 12
Tear Break Up Time was analyzed using the average of the readings of both eyes. TBUT is defined as the time (seconds) required for dry spots to appear on the surface of the eye after blinking. The longer it takes, the more stable the tear film.
Time frame: Week 12
