[Surgical effects of trabeculotomy after long-term topical antiglaucoma medications]

We retrospectively analyzed the effects of long-term topical antiglaucoma therapy on the results of trabeculotomy. We studied 83 eyes with 76 primary open angle glaucoma and 7 eyes with capsular glaucoma, each of which had undergone trabeculotomy alone and none of which had a history of laser trabeculoplasty or glaucoma surgery. The outcome of trabeculotomy was assessed after a minimum follow-up of 12 months. Using a life-table method, there was no significant difference in the outcome of trabeculotomy between groups divided by duration and type of preoperative topical therapy. There was not statistically significant difference in the intraocular pressure reduction between the groups of long or short duration of topical therapy. We concluded that the duration and type of topical antiglaucoma medications had no significant effect on the outcome of trabeculotomy.
