Schematic of Baerveldt 350 placement. (A) Typical placement of a Baerveldt 350 GDD approximately 8 mm posterior to the limbus such that the plate sits behind the insertions of the superior (SR) and an un-operated lateral rectus (LR) muscle. The plate lies along the equator of the globe, parallel to the limbus. (B) Placement of the plate of a Baerveldt 350 GDD behind a 9 mm recessed LR. In order to fit the plate behind the recessed muscle, the plate may need to be rotated such that it is not parallel to the limbus
