Purpose:
To compare the effects of mitomycin C (MMC) and paclitaxel entrapped within Carbopol 980 hydrogel (CH) on conjunctival wound healing.
Methods:
Twenty rabbits were randomized into 2 groups. In group 1, limbal-based conjunctival flaps were created in both eyes. In this stage, eyes were randomized for 4 different processes. In process 1, a dry cellulose sponge soaked with 0.2 mg/mL of MMC was applied to the scleral surface. A cellulose sponge soaked with balanced saline solution was applied in the same manner in process 2. In process 3, paclitaxel 1 mg/mL entrapped within CH was placed between the conjunctiva and sclera. In process 4, CH without paclitaxel was applied in the same manner. The conjunctiva was then sutured. All procedures were applied in the same manner in both eyes of animals in group 2. Eyes from group 1 were sampled at the seventh day, and the sampling was also carried out in group 2 on day 14. The inflammatory response and fibrosis were evaluated with light microscopy.
Results:
Among 4 different processes, lower cell counts and fibrosis scores were found in eyes treated with MMC and paclitaxel compared with balanced saline solution and CH groups (P<0.05). There was no difference between eyes treated with MMC and paclitaxel in terms of these histopathologic parameters (P>0.05).
Conclusions:
Paclitaxel was shown to provide MMC-like antifibrotic effects during conjunctival wound healing, particularly when delivered with CH and might be a promising alternative as an adjunctive antimetabolite in glaucoma filtration surgery.
