Philadelphia, Pennsylvania 19107


To determine whether one glaucoma eye drop is less likely to cause changes to the surface of the eye (conjunctiva) than another. The two different prostaglandins are Xalatan and Travatan Z.

Study summary:

Two groups will be entered into this study: group 1 will be naive to treatment and group 2 will be using Xalatan for at least one month before enrollment. Both groups will be using one drop at bedtime of Xalatan in the right eye and one drop at bedtime of Travatan Z in the left eye. Both of these drops are presently on the market and approved by the FDA for treatment of lowering eye pressure. Because this study will be masked, the examining clinician will not know what study drop each patient has been using.
