Abstract
- The prior long-term use of topical anti-glaucoma medications has been suggested as an adverse factor for the outcome of trabeculectomy. The mechanism of action is still unclear. This study investigates the effect of Trusopt and Xalatan on the proliferation and viability of human Tenon`s capsule fibroblasts in tissue culture. We examined the effect of two commercial drugs, Trusopt and Xalatan, and pure benzalkonium chloride, at various dilution, on the proliferation as assessed by MTT assay and assessed micro-scopically the viability of human Tenon's capsule fibroblasts in tissue culture. None of the tested compounds stimulated proliferation of fibroblasts in tissue culture and inhibited proliferation. All had toxic effects on cell morphology. These results show an antiproliferative and toxic effect of Trusopt and Xalatan on the fibroblasts in tissue culture and no direct stimulation of fibroblast proliferation.
