Brimonidine Tartrate for Pterygium Surgery
Summary
Pterygium excision and conjunctival autograft surgery is commonly done to treat pterygiums. Excessive bleeding during the procedure creates a challenging operating field, prolongs surgery time, and prolongs healing. Brimonidine tartrate has a vasoconstrictive effect, which helps to reduce the amount of blood flow and hyperemia to the eye. Preoperative use of brimonidine has been shown to decrease subconjunctival hemorrhage during procedures such as cataract surgery, laser assisted in situ keratomileusis, strabismus surgery, and intravitreal injections. The focus of this study is to assess the effect of preoperative application of brimonidine tartrate 0.15% (Alphagan) and 0.025% (Lumify) on reducing hemorrhage during pterygium excision and conjunctival autograft surgery.
