Ab Interno Ahmed Glaucoma Valve Plugs In An Eye With Persistent Hypotony.

PURPOSE:This case report aims to describe a new method for increasing intraocular pressure (IOP) in patients with acute hypotony resulting from uveitis flare-ups and preexisting glaucoma drainage devices. The temporary glaucoma tube plug method described is effective and safe. METHODS:This case report presents a 47-year-old female patient with a history of chronic panuveitis and secondary glaucoma, who had 2 previously implanted Ahmed glaucoma valves. The patient developed panuveitis flare-up and persistent hypotony. A novel method of ab interno plugging of the glaucoma tubes using 2-0 prolene suture plugs was performed. Following treatment, the IOP increased successfully and remained within the normal range. CONCLUSION:The temporary ab interno glaucoma tube plug method effectively increased IOP in a patient with 2 preimplanted Ahmed glaucoma valves with persistent low IOP due to uveitis.
