Evaluation of the early results of ab interno trabeculectomy surgery appllied with trabectome device

Abstract

The aim of the current study was to assess efficacy and safety of ab interno trabeculectomy surgery applied with trabectome device in early period. The study was designed among the 30 eyes of 26 patients who had undergone trabectome surgery with the diagnosis of open-angle glaucoma. Patients were evaluated as retrospectively in terms of preoperative and postoperative intraocular pressure (IOP), number of drugs used and complications. While the preoperative mean IOP was 28.78±5.57 mmHg (n:30) with the mean number of medications 3.40±1.04, the mean IOP was 18.24±5.54 mmHg (n:30) with the mean number of medications 0.90±1.27 at 1st month. At 3rd month the mean IOP was 16.37±3.36 mmHg (n:28) with the mean number of medications 0.70±1.10 and at 6th month the mean IOP was 16.51±3.80 mmHg (n:28) with the mean number of medications 1.13±0.96. When postoperative measurements compared with preoperative values, detected reductions in IOP and number of medications were statistically significant (p<0.01). Postoperatively decrease in IOP was 40% at 1st month, 38.1% at 3rd month and 33.4% at 6th month while the reduction in the number of medications was 73.5% at 1st month, 79.8% at 3rd month and 65.8% at 6th month. Trabectome surgery is a effective and safe option for open-angle glaucoma. This procedure is an appropriate surgical alternative for patients that targeted to have IOP at moderate levels without need for any topical medication or with less topical medication
