PURPOSE: To describe a new technique to treat late persistent hypotony after Baerveldt glaucoma drainage device surgery. METHODS: Review of 2 cases treated with in situ truncation of one or both wings of the Baerveldt device, combined with permanent but releasable tube occlusion. RESULTS: Two eyes with persistent hypotony underwent in situ truncation of one or both wings of the Baerveldt device with resolution of hypotony. Recurrence of elevated intraocular pressure (IOP) in both cases required reversal of tube occlusion, after which the IOP has remained both well controlled and sufficiently elevated to avoid complications of hypotony over 13 and 43 months...

PURPOSE: The measurement of intraocular pressure (IOP) by Goldmann applanation tonometry (GAT) is based on assumptions about corneal parameters. To correct for variations in corneal curvature and thickness, a number of equations have been proposed. This study evaluates the in vivo accuracy of these equations from individuals with primary open-angle glaucoma and compared them with measurements taken using the Pascal dynamic contour tonometer (DCT), which makes no assumptions about the corneal geometry or biomechanics...
