Outcomes of Ahmed Glaucoma Valve Implantation With Viscoelastic Fill at Both Beginning and End of Surgery
Précis:
Intracameral injection of viscoelastic at the beginning of Ahmed FP7 implantation did not reduce early postoperative complication rates.
Purpose:
To evaluate early postoperative complication rates after a modified technique in which the anterior chamber (AC) is filled with viscoelastic at the beginning of Ahmed FP7 implantation before conjunctival peritomy.
Subjects and Methods:
A retrospective chart review was performed of eyes that underwent Ahmed FP7 implantation with or without viscoelastic fill to ~20 mm Hg by finger tension by a single surgeon (M.R.M). Viscoelastic prevented the AC from becoming shallow at any time during surgery, and additional viscoelastic was injected into the AC at the end of surgery to achieve a final intraocular pressure (IOP) of 20 mm Hg.
Results:
A total of 159 eyes of 159 patients were included. Mean age was 76.4±10.4 years. Mean preoperative IOP was 30.3±9.7 mm Hg on 2.7±1.2 glaucoma medications. On postoperative day 1, there was an IOP spike ≥30 mm Hg in 0% of patients. Within the first postoperative month, hypotony (
