Abstract
 
Purpose
 

We retrospectively investigated the complications and results of two different tube ligation methods: releasable suture ligation using 8-0 polyglactin (group A) and unreleasable suture ligation using 7-0 nylon (group B), three months after Baerveldt implant surgery.

 
Methods
 

After excluding the eyes with combined surgery of trabeculectomy (24 eyes), stent methods (1 eye) and complication of tube or plate exposure (5 eyes), 70 eyes of 67 patients were used for this study. The surgery was performed by a single surgeon (TH). Groups A and B were composed of 20 eyes of 18 patients and 50 eyes of 49 patients, respectively. In group A, the tube was ligated within 5 mm before the plate. In group B, the tube was ligated 2 mm from the tip of the tube and inserted into the anterior chamber, and then the tube was released using an argon laser when the intraocular pressure (IOP) exceeded 21 mmHg. Ocular hypertension, hypotension and cilio-choroidal detachment were reviewed for three months after the surgery. This study was approved by the IRB of the Japanese Red Cross Medical Center.

 
Results
 

High IOP occurred significantly more often in group B (p=0.035), but the success rates did not differ significantly between the two groups (p=0.389).

 
Conclusions
 

Both ligation methods were revealed to be useful, but the unreleasable suture method should not be used for eyes with severely advanced glaucoma.
