Long-term results of anterior chamber tube shunt to an encircling band in the treatment of refractory glaucomas.
We performed the anterior chamber tube shunt to an encircling band procedure in 34 patients (36 eyes) with refractory glaucoma, and evaluated the long-term outcome. The preoperative mean intraocular pressure (IOP) was 36.8 +/- 9.6 mmHg, the postoperative mean IOP was 21.6 +/- 13.6 mmHg, a statistically significant (p < 0.01) reduction of IOP following this procedure. The final postoperative IOP was under 21 mmHg in 23 (63.9%) of the 36 eyes. The success rate of IOP control 36 months after the operation without any elevation of post-operative IOP was 30.3% (life-table method). Complications of this procedure included flattening of the anterior chamber (61.1%), damage to the corneal endothelium (25%), hyphema (25%), and a transient IOP elevation (25%). As filtering surgery with 5-fluorouracil is more effective and simple to perform, we conclude that the anterior chamber tube shunt to an encircling band procedure should be reserved for those with refractory glaucoma who have had multiple surgical interventions.
