Conjunctival scarring is one of the difficulties long associated with glaucoma surgeries such as trabeculectomy. This part of the healing response can undo the benefits of the glaucoma surgery by closing down the channels created to allow aqueous to escape and thus reduce intraocular pressure. For that reason, minimizing scarring has become an important part of these surgeries. One of the most effective ways to control scarring has turned out to be through the application of mitomycin-C. The most commonly used method of applying mitomycin-C during glaucoma surgery is to soak a Weck-Cel sponge in a solution of the drug and then apply the sponge to the ocular tissues for a few minutes. However, many surgeons, including those in our practice, use a different approach; we inject the mitomycin-C directly into the conjunctival tissue. Our surgical results have been just as good since switching to this method, and it appears to have some potentially significant advantages over the sponge method. Here, I’ll discuss the benefits and limitations of each technique.
