Abstract Details

Purpose:

To investigate the efficacy of trabeculae ablation ab interno with a forceps (endotrabeculoectomy) after failed glaucoma surgery.

Setting:

Lviv 8-th city hospital, Lviv, Ukraine

Methods:

56 patients (56 eyes) after failed glaucoma operations of filtering type were observed. 24 of them undergone trabeculoectomy, 26 – deep sclerectomy, 6 – implantation of EX-PRESS shunt. Meantime after surgery was 41.3±7.2 months. Operation endotrabeculoectomy alone was performed for 31 aphakic eyes and combined surgery – phaco and endotrabeculoectomy – for 25 eyes. Trabecular meshwork was ablated for about 90° to 120°. The intraocular pressure (IOP) and the number of glaucoma medications were recorded before, and 1 week, and 1, 3, 6, 12, 18, 24, 30, and 36 months after the surgery. The intra- and postoperative complications were recorded.

Results:

The mean preoperative IOP was 21.6±2.2 mmHg. The mean preoperative number of glaucoma medications was 2.6±0.8. At 1 week after operation, the IOP reduced by 6.8±1.6 mmHg (р<0.001) and was 14.4±1.7 mmHg. At 3, 6, 12, 18, 24, 30, and 36 months IOP was 14.9±1.5; 15.0±1.4; 14.8±1.3; 14.9±1.5; 15.1±1.6; 15.2±1.4 and 15.4±1.6 mmHg. The number of medication was 0.7±0.3; 0.8±0.5; 1.0±0.7 and 1.1±0.7 at 3, 12, 24 and 36 months after the surgery (р<0.001).

Conclusions:

Endotrabeculoectomy is a safe and effective option following failed previous glaucoma surgery.
