Further study details as provided by University of Cologne:

Estimated Enrollment: 30
Detailed Description:
Despite the adjuvant use of mitomycin C during trabeculectomy, short-term and long-term failures still occur. We investigate whether mitomycin C treatment during previous trabeculectomy induces P-glycoprotein expression. Expression of P-glycoprotein is analysed in surgically removed Tenon tissue using immunohistochemistry.

Ages Eligible for Study:   8 Years to 85 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • patients with planned trabeculectomy for elevated eye pressure
  • one third of patients without previous trabeculectomy
  • two thirds of patients with previous trabeculectomy (one third with and one third without the use of mitomycin C)

Exclusion Criteria:

  • patients not requiring surgery
  • patients with planned surgery for elevated eye pressure other than trabeculectomy
