This study will evaluate the efficacy and safety of the use of bevacizumab (Avastin) as an adjunctive medication during pterygium surgery in preventing pterygium recurrence. A pterygium is a white fleshy growth on the surface of the eye, which can be removed surgically. However, after surgical removal, pterygia can recur. One way of minimizing recurrence is by applying a medication called mitomycin C to the surface of the eye during pterygium surgery. However, mitomycin is associated with certain side effects, such as thinning of the eye wall and poor wound healing. Bevacizumab has a different mechanism of action and there is some evidence that it may be useful in preventing pterygium recurrence. In this study, the safety and efficacy of adjunctive intraoperative use of bevacizumab and mitomycin C for preventing pterygium recurrence will be directly compared.

To evaluate changes in endothelial cell count after pterygium surgery with mitomycin C (MMC) 0.02%
This is a randomized controlled trial of postoperative bevacizumab or 5-fluorouracil subconjunctival injections vs placebo for the recurrence of pterygia after excision using conjunctival ...
Pterygium is characterized by encroachment of a ﬂeshy fibrovascular tissue from the bulbar conjunctiva on to the cornea. Although previously thought to be a solely degenerative disease, ...
1. CBT-001 administered three times daily (TID) for 4 weeks has an acceptable safety profile when used in pterygium patients 2. CBT-001 administered TID for 4 weeks is more effecti...
Pterygium is known to induce with-the-rule astigmatism. Excision of pterygium will steepen the cornea and reduce corneal astigmatism. We postulate that the alteration of keratometry readin...
To determine whether scleral topical application of mitomycin-C (MMC) results in measurable plasma levels of systemic absorption.
Pterygium is composed of proliferating fibrovascular tissue, and its formation and progression are closely related to the homeostasis of the extracellular microenvironment. However, few studies have e...
The objective of this study was to evaluate the efficacy and safety of bevacizumab combined with antimetabolite as an adjunctive therapy in primary trabeculectomy for glaucoma.
Pterygium is one of the modern problems of ophthalmology. The exact etiology and pathogenesis of this disease has not been reliably established and, as a result, there is no universal method for its r...
Anti-fibrotic, anti-VEGF (vascular endothelial growth factor) medications, or radiotherapy, as adjuvant for pterygium surgical procedure, has been suggested for reducing recurrence, but difficulties m...
Toxic antibiotic of the mitomycin group, obtained from MITOMYCIN and also from Streptomyces ardus and other species. It is proposed as an antineoplastic agent, with some antibiotic properties.
An anti-VEGF recombinant monoclonal antibody consisting of humanized murine antibody. It inhibits VEGF receptors and prevents the proliferation of blood vessels.
An enediyne that alkylates DNA and RNA like MITOMYCIN does, so it is cytotoxic.
An abnormal triangular fold of membrane in the interpalpebral fissure, extending from the conjunctiva to the cornea, being immovably united to the cornea at its apex, firmly attached to the sclera throughout its middle portion, and merged with the conjunctiva at its base. (Dorland, 27th ed)
An antineoplastic antibiotic produced by Streptomyces caespitosus. It is one of the bi- or tri-functional ALKYLATING AGENTS causing cross-linking of DNA and inhibition of DNA synthesis.
