PURPOSE: To evaluate the effects of mitomycin C and amniotic membrane transplantation on the modulation of wound healing after glaucoma filtration surgery. METHODS: Trabeculectomy was performed in three groups of ten rabbit eyes each. Sponges soaked in mitomycin C were applied to the first group, and amniotic membranes were transplanted around the scleral flap in the second group; the third group was the control. The arithmetic means of fibroblast and macrophage numbers per square centimetre were calculated. RESULTS: The mean numbers of fibroblasts and macrophages were decreased significantly in the mitomycin C group, compared with the controls (p < 0.0001). Cell counts in the amniotic membrane group were also lower than the ones in the control group for fibroblasts and macrophages (p < 0.0001, p < 0.01, respectively). The difference between the two treatment groups was statistically significant for fibroblasts (p < 0.0001), but not significant for macrophages (p > 0.05). CONCLUSION: Despite the fact that amniotic membrane transplantation is less effective than mitomycin C for depressing wound healing after trabeculectomy, it might be a safer alternative in selected cases when considering severe adverse effects of antimetabolites.
