NCT02162043
This project aims to evaluate a self-administered screening test for glaucoma, the second largest cause of blindness in the western world. New approaches to glaucoma screening are needed because a significant number of patients first present to hospitals with advanced-stage glaucoma and late presentation is associated with a much higher risk for future blindness. This project will develop a new user-friendly visual field test that will be made available through the internet for self-testing. It will conduct both hospital-based and community-based clinical trials to establish benefits and costs of this new test.

Strictures in the bile duct cause a blockage of flow of bile. This leads to potential problems including jaundice, itch and infection in the bile duct. The usual first step in this situation would be to allow flow of bile by placing a stent across the stricture. This is usually done by a special type of endoscopy procedure called an endoscopic retrograde cholangiopancreatography, or ERCP. The most commonly used stent are made from a plastic material called polyethylene and has a central lumen in which bile drains through it. Health Canada has approved the sale and use of another stent with a winged perimeter (the VIADUCT stent) for placement in bile duct strictures and is used routinely in our hospitals. However, the investigators do not know which stent is better at treating bile duct strictures. In order to determine which stent would be more useful, the VIADUCT stent and the usual polyethylene flanged stent must be studied under carefully controlled circumstances. This will be done by a randomized, subject-blinded study. Other trials in the past have looked at other stents in this way, but this is the first time the VIADUCT stent has been looked at in this manner. The investigators suspect that the design of the VIADUCT stent will allow it to work for a longer period of time compared to the traditional polyethylene stent.
