Abstract |
Viscoelastic substance or Mitomycin C(MMC)is not necessarily used in trabeculectomy. Hence, the authors investigated the rate of cataract development or progression after trabeculectomy related with using of the viscoelastic substance or MMC. The authors evaluated 119 eyes undergoing trabeculectomy and divided these eyes into 4 groups :group 1, 2, 3, and 4. In group 1, viscoelastic substance or MMC was not used(27 eyes). In group 2, only viscoelastic substance was used(35 eyes). In group 3, only MMC was used(15 eyes). In group 4, both viscoelastic substance and MMC were used(42 eyes). The cataract development or progression was examined with slit-lamp biomicroscope at postoperative 6 months and defined as the decrease of visual acuity more than 2 lines. The rate of cataract development or progression at postoperative 6 months was 18%in group 1, 14%in group 2, 40%in group 3, and 19%in group 4.The use of MMC without viscoelastic substance in trabeculectomy influenced cataract development or progression extremely. In conclusion, the results of this study suggest that the viscoelastic substance may reduce the rate of cataract development or progression after trabeculectomy in which MMC is used besides. |
