This research is being done to compare the safety and effectiveness of two sizes of the Baerveldt glaucoma implant.
A Baerveldt glaucoma implant is one of the most common types of glaucoma operations performed. This procedure works by providing a route by which fluid can drain out of the eye to decrease the intraocular pressure. The Baerveldt implant does this by placing a tube into the eye which shunts aqueous fluid to a silicone plate which is attached to the sclera (white portion of the eye). It is this plate that comes in two different sizes (250 square millimeters and 350 square millimeters).
Earlier studies have shown that larger plate sizes produce lower eye pressures but that they may also result in more complications. While both Baerveldt devices are currently in use and have been shown to be safe and effective, it is unclear if one is superior to the other. The purpose of this study is to see if one size of device works better with fewer complications.

Changing an operative procedure from an endoscopic surgical procedure to an open approach during the INTRAOPERATIVE PERIOD.
Surgical procedure in which the STOMACH is transected high on the body. The resulting small proximal gastric pouch is joined to any parts of the SMALL INTESTINE by an end-to-side SURGICAL ANASTOMOSIS, depending on the amounts of intestinal surface being bypasses. This procedure is used frequently in the treatment of MORBID OBESITY by limiting the size of functional STOMACH, food intake, and food absorption.
A surgical procedure which diverts pancreatobiliary secretions via the duodenum and the jejunum into the colon, the remaining small intestine being anastomosed to the stomach after antrectomy. The procedure produces less diarrhea than does jejunoileal bypass.
A set of surgical procedures performed to establish sufficient outflow to the systemic circulation in individuals with univentricular congenital heart malformations, such as HYPOPLASTIC LEFT HEART SYNDROME, and MITRAL VALVE atresia, associated with systemic outflow obstruction. Follow-on surgeries may be performed and consist of a HEMI-FONTAN PROCEDURE as the stage 2 Norwood procedure and a FONTAN PROCEDURE as the stage 3 Norwood procedure.
Ophthalmology is the branch of medicine that is devoted to the study and treatment of eye diseases. As well as mild visual defects correctable by lenses, ophthalmology is concerned with glaucoma, uveitis and other serious conditions affecting the eye, ...
