Baerveldt (BGI) Valve Versus Ahmed(AGV) Valve in Management of Difficult Glaucoma Cases
GlaucomaOpen-Angle5 moreRefractory glaucoma is a difficult subject as many glaucoma devices attempt to reduce IOP. Baerveldt implant is considered as a large implant, and, on the contrary, Ahmed implant is considered a small implant as many comparisons have showed. Investigators have previously used two models S2 and FP7 Ahmed implant. Currently, investigators use Baerveldt implant in refractory glaucoma cases in order to compare it with the Ahmed implant.
Comparing Conscious Sedation to Retrobulbar Block Anesthetics During Trans-scleral Diode Laser
GlaucomaThis is a non-inferiority trial with a prospective randomized controlled design assessing patient satisfaction and complications associated with both retrobulbar block anesthetics (current gold standard) and conscious IV sedation alone (alternative choice of anesthesia) for trans-scleral diode laser (TSD). Patient satisfaction and complications will be measured using standardized patient surveys.

Effect of Travoprost 0.004% on Retinal Oximetry in Primary Open Angle Glaucoma
Primary Open Angle GlaucomaGlaucoma is the second leading cause of blindness among seniors in Canada. It is often associated with an elevated intraocular pressure (IOP), but its exact mechanism is still largely unknown. Some studies have shown a link between glaucoma and changes in the amount of oxygen in the veins of the eye. The study aims to compare the amount of oxygen in ocular veins among three different groups using a spectrophotometer. This instrument is linked to a camera and can measure the quantity of oxygen in the veins using different characteristics of the blood inside. The groups of the study are: patients without glaucoma, patients suspected of glaucoma and patients newly diagnosed with glaucoma. The drug the investigators are using, Travoprost 0.004%, will only be administered to the groups suspected or diagnosed with glaucoma. Travoprost 0.004% is already approved for use in Quebec and is part of standard care. Ten patients will be recruited into each group for a total of 30 patients in this study. All patients for the suspected or diagnosed groups will be recruited from the Jewish General Hospital. Subsequently all testing will be done at the École d'optométrie, Université de Montréal
