PURPOSE To describe a pilot study that evaluates the efficacy and mechanism of action of a new glaucoma operation, trabeculectomy with internal tube shunt. METHODS Twenty-three patients underwent the new operation in one eye for open angle glaucoma. Under a scleral flap, a deep sclerectomy was performed, resulting in an intrascleral lake. Laterally, on both sides, a small silicone tube was pl...

In recent years, the rapid development of diagnostic optic devices has generated optical coherence tomography (OCT) as a new, non-invasive diagnostic method. With technical progress of the infrared spectrum at 1,310 nm, OCT of the anterior segment also became feasible. With anterior segment OCT different examinations which so far were ruled out by ultrasound in contact manner could be executed ...

Filtering procedures for glaucoma in Africans are considered to be failures owing to their propensity for increased fibrosis. However, favourable results from trabeculectomy in African patients with glaucoma are reported. Most of these are from such modifications of technique as non-suturing of flaps, sclerectomy, posterior lip cautery, or administration of high doses of steroids. In this study...
