The use of the single stage Molteno long tube seton in treating resistant cases of glaucoma.

The Molteno long tube seton was used in 12 eyes with glaucoma. The seton was inserted in one stage. Seven of the 12 eyes had previous filtration surgery which had failed. All the eyes had intraocular pressures below 24 mm Hg over an average follow-up period of 14 months. Prolonged postoperative hypotony was the biggest problem following seton implantation as a one-stage procedure. One of the eyes became pthisical. The Molteno seton may be used to treat neovascular glaucoma, or glaucoma which has failed to respond to previous filtration surgery.
