Intraoperative testing of opening and closing pressure predicts risk of low intraocular pressure after Ahmed glaucoma valve implantation.

摘要

AGVs have a high variability of opening, closing, and re-opening pressures. An opening pressure of ≤18?mm?Hg, a closing pressure of ≤10?mm?Hg, or a re-opening pressure of ≤11?mm?Hg identified all patients with low postoperative IOP.
