Summary

Rationale: The Baerveldt glaucoma drainage device (GDD) successfully reduces intraocular pressure but also involves a risk of corneal endothelial deterioration. Supposedly, the tip of a GDD tube with a thinner diameter, such as the Paul implant, will remain at a larger distance from the cornea and, thereby, cause less damage.

Objective: To determine whether the Paul tube induces less damage to the corneal endothelium than the Baerveldt GDD.

Study design: Randomized clinical trial. Study population: Phakic patients scheduled for surgical GDD implantation. Intervention: Either a Baerveldt or a Paul GDD implant. Main study parameters/endpoints: Endothelial cell density and tube position at 24 months.

Nature and extent of the burden and risks associated with participation, benefit and group relatedness: The Paul GDD may have a less harmful effect on corneal endothelium. Otherwise, both GDDs will probably have a similar risk/benefit profile. The risks of study-related assessments are negligible, burden is low, extra time is about 5 x 1.5 h (total 7.5 h) in two years.

Conditions

Interventions

DEVICE

Surgery/implantation

The glaucoma drainage device consists of a plate and a tube. During surgery the plate is positioned underneath the conjunctiva and two extraocular muscles in the upper temporal quadrant of the eye. The tube is positioned in the anterior chamber.
