  Purpose

The purpose of this study was to assess the pigmentation in the trabecular meshwork of patients who had been treated for at least 2 years with TRAVATAN compared with patients without exposure (or less than 1 month) to a prostaglandin analogue (PGA).

Primary Outcome Measures:
  • Melanin Granule Count [ Time Frame: Day 1 ] [ Designated as safety issue: Yes ]
    A trabecular meshwork tissue sample was collected by the investigator. The number of pigment granules was counted for three separate microscopic fields of view. Mean melanin granule count was calculated.

Groups/Cohorts Assigned Interventions
TRAVATAN
As prescribed by physician for the treatment of open-angle glaucoma and dosed for at least two years
 Procedure: Trabecular Meshwork Tissue Collection
A minimum of two punches were used to remove tissue to form a sclerostomy. Tissue removed by the punch was collected for analysis. Alternatively, the tissue was collected by block excision of the meshwork with scissors at the time of sclerostomy.
Drug: Travoprost 0.004% ophthalmic solution
Other Names:
  • TRAVATAN Z
  • TRAVATAN
Treatment Naive
No prior exposure (or less than 1 month) to any topical, ocular prostaglandin analogue
 Procedure: Trabecular Meshwork Tissue Collection
