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.
