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 1st month, 15.47± 1.1mmHg at 3rd month, 15.02±1.8 mmHg at 6th month, 15.34± 2.1 mmHg at 1styear, 15.82 ± 2.1mmHg at 2nd year, 17.06 ± 2.3mmHg at 5th year and 18.02 ± 2.2 mmHg at 10th year. Statistical analysis of these data showed significant decreased of intra ocular pressure in the post operative period in compare to the preoperative period, 1st month, 3rd month, 6thmonth, 1st year, 2nd year, 5th year an 10th 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.
