Pterygium Clinical Trial
Official title:
Comparison Between Topical Mitomycin C and Cyclosporine After Primary Pterygium Surgery
Pterygium is a disease associated with proliferation of the fibrovascular tissues of the conjunctiva into the cornea and is related to factors such as ultraviolet light exposure, chronic stimulation, inflammation, climate, and genetics.
The first line of treatment for primary pterygium is surgical excision, and despite postoperative adjuvant therapy using mitomycin C, cyclosporine, β-irradiation, argon laser, and bevacizumab, recurrence rates remain high . Mitomycin C is a metabolic inhibitor extracted from Streptomyces caespitosus that inhibits DNA synthesis . Cyclosporine is an immunosuppressant that selectively suppresses T-helper cells, controls interleukin synthesis and secretion, and inhibits vascular endothelial growth factor (VEGF) Bevacizumab is an anti-VEGF antibody that inhibits angiogenesis. Each agent has been studied as an adjuvant therapy to inhibit post-surgery pterygium recurrence. ;
