Glaucoma Drainage Device Technique in a Cohort of Experienced Glaucoma Surgeons in Australia and New Zealand
Glaucoma drainage devices (GDD) by Australian and New Zealand glaucomatologists are implanted superotemporally under a peribulbar anesthesia without the use of mitomycin C. Intraluminal stents and tube fenestration are utilized and covered with a scleral graft.
PURPOSE: To evaluate current practice patterns of surgical techniques for GDD among Australia and New Zealand Glaucoma Society members routinely performing GDD surgery.
METHODS: Survey of surgeons who performed more than 20 GDD in past 5 years.
RESULTS: Surgeon participation rate was 31/32 (96.8%). The most common surgical techniques were Baerveldt GDD (24/32, 77.4%), superotemporal placement (31/31, 100%), and peribulbar anesthesia (21/31, 67.7%). Mitomycin C antimetabolite was used routinely by 9/31 surgeons (29.0%). Most surgeons employed intraluminal stents (23/31, 74.2%) with tube fenestrations (19/31, 61.3%). GDD was placed behind the recti muscles (27/31, 87.1%) and secured with nylon (8/0, 9/0 or 10/0) by 29/31 (93.6%). Most common sclerostomy techniques for tube insertion was a 23-G needle passed ab externo (18/31, 58.1%). Tube placement was in the sulcus (11/31, 35.5%) for pseudophakic patients. The external portion of the tube was most commonly covered with a full-thickness scleral patch graft (21/31, 67.7%). Majority of surgeons (21/31, 67.7%) reviewed patients 3 to 4 times in the first month.
CONCLUSIONS: Although a wide range of practice patterns for GDD implantation exists among Australia and New Zealand Glaucoma Society surgeons, there are consistent techniques currently in use to optimize patient outcomes. This report can help surgeons seeking to improve outcomes and minimize complications when trialing the different surgical options.
