Trabeculectomy in glaucoma:A review

ABSTRACT

OBJECTIVE:To determine surgical outcome of patients who underwent trabeculectomy in our institution METHODOLOGY:The medical records of glaucoma patient who underwent primary trabeculectomy from 1998 - 2000 in our institution are reviewed.All types of glaucoma are included except congenital and developmental glaucoma.Surgical outcome is assessed in terms of final intraocular pressure (IOP).Outcome is defined as a success when the post-operative IOP is 21 mm Hg or lower.The operation is a failure if IOP is greater than 21 mm Hg despite medication and suture lysis.Data are analyzed using the Chi-Square test. RESULTS: 56 eyes of 45 patients are included in the study.Mean age is 59 - 70 years with s standard deviation (SD) of +_9.50.Mean follow-up is 8 months (SD +_7.97).Of the the 56 eyes, success is obtained in 43 eyes (76%), qualified success is achieved in 8 eyes (14.3%) and failure is seen in 5 eyes (8.9% which is evident on the 14th month +_ 11.39 months.There is a significant number of unsuccessful cases when compared to failed cases (p<(p<0.05 ) respectively.However, no sigificant difference existed between qualified success and failed cases (p<0,05).Increase in pressure is observed between 5 and 10 months after trabeculectomy.Mean pressure is highest during the 5th month. CONCLUSION:There is a high success rate of patients who underwentrabeculectomy in our institution
