Long term results of trabeculectomy surgery

Abstract

Objective: Evaluation of long-term results of primary trabeculectomy operation

Methods: The cases that are followed up with diagnosis of glaucoma in Okmeydanı Training and Research Hospital Eye Clinic between January 2000 and December 2001 were evaluated retrospectively. All of the cases, despite maximum therapy, have high intraocular pressure (IOP), undergone primary trabeculectomy operation, are followed at least 6 months and regularly followed through 10 years were included in this study. IOP with or without medical treatment 18mmg or less than 18 mmHg accepted as successful. IOL pressure measured with applanation tonometry.

Results: 89 eyes of 70 cases were included in this study. The cases included in the study, 42 male (60%), and 28 (40%) were female. The mean age was 63.65±12.18 years. Preoperative intraocular pressure determined as 30.36 ± 3.2 mmHg. In the follow up examination mean intra ocular pressure was 15.31 ± 1.2 mmHg at 1^st month, 15.47± 1.1mmHg at 3^rd month, 15.02±1.8 mmHg at 6^th month, 15.34± 2.1 mmHg at 1^styear, 15.82 ± 2.1mmHg at 2^nd year, 17.06 ± 2.3mmHg at 5^th year and 18.02 ± 2.2 mmHg at 10^th year. Statistical analysis of these data showed significant decreased of intra ocular pressure in the post operative period in compare to the preoperative period, 1^st month, 3^rd month, 6^thmonth, 1^st year, 2^nd year, 5^th year an 10^th year (p < 0.01). The follow-up period in the study was 91.10 ± 40.15 months (6-120 months).

Conclusion: Primary trabeculectomy can be considered as an alternative treatment procedure especially in patients who does not use drugs regularly and unable to attend regular medical examination.
