The retrospective study of trabeculectomy in at Srakaeo Crown Prince Hospital.

Abstract

Objective : To study the results of trabeculectomy in term of intraocular pressure control and visual acuity.

Material and method : A retrospective chart review of all patients underwent trabeculectomy in Srakaeo Crown Prince Hospital from October 2003 to March 2009 was performed. The collected data included age, sex, laterality, type of glaucoma,visual acuity, intraocular pressure, cup disc ratio, number of medications and result after operation.

Results : Trabeculectomy was done in 51 eyes of 47 patients with the mean age of 58.7±11.0 years. Most frequent types of glaucoma were primary angle closure glaucoma (45.1%), primary open angle glacoma (21.6%), uveitic glaucoma (7.8%), traumatic glaucoma (7.8%) and neovascular glaucoma (7.8%) respectively. The mean cup disc ratio was 0.83±0.18. The intraocular pressure was reduced from 45.6±11.9 mmHg preoperatively to 16.7±8.7 mmHg postoperatively. The number of medications received was reduced from 3.4±1.1 preoperatively to 1.4±1.4 postoperatively. The visual acuity was stable with the mean follow -up time was 20.1±16.1 months.

Conclusion : Trabeculectomy can control intraocular pressure and preserve visual acuity and should be considered for the patients in source limited area and poor compliance.
