The technique described in this paper shows how to use a long scleral tunnel for the implantation of anterior tube parts of glaucoma drainage devices. It involves the creation of a scleral tunnel starting 10 mm behind the limbus and extending to the anterior chamber. The anterior tube parts of a Krupin eye valve with disc are inserted through the scleral tunnel to the anterior chamber. The disc part is secured to the episclera, as in the standard technique. The authors have used this technique in six eyes of six consecutive patients with refractory glaucoma. The placement of anterior tubes as part of glaucoma seton devices was performed in all patients. While mean intraocular pressure (IOP) was 39.3 ± 4.9 mmHg (range, 29-56 mmHg) preoperatively, it was 16.6 ± 5.3 mmHg (range, 11-25 mmHg) at the end of follow-up. Mean follow-up time was 7.16 ± 1.16 months (range, six to nine months). After surgery, no conjunctival erosion or displacement of the anterior tube and dellen formation were found in any of the eyes. The use of a long scleral tunnel for the implantation of anterior tube parts of glaucoma seton devices offers some advantages over standard implantation techniques.
