Abstract:

To analyze the cause and management of shallow anterior chamber after trabeculectomy of glaucoma.［Methods］ 126 cases(151 eyes) were operated with routine trabeculectomy of glaucoma. ［Results］ 29 cases(32 eyes) with the postoperative complication of shallow anterior chamber, the incidence rate was 21.2%. The depth of shallow anterior chamber has been classified according to Spaeth Classification.Shallow anterior chamber grade I in 23 eyes, grade II in 7 eyes,grade III in 2 eyes. Of all the 32 eyes, 22 eyes with much more filtering,2 eyes with conjunctival flap flushing, 7 eyes choroidal detachment. They were managed with non-surgical therapy.1 eye with malignant glaucoma,it was managed with surgical therapy. ［Conclusions］The common cause of shallow anterior chamber after trabeculectomy is excessive aqueous homor drainage . Through conservative treatment, most patients with shallow anterior chamber grade I - II can be cured.Shallow anterior chamber grade III can be cured through surgical therapy.
