Abstract
Case report: We report the case of a 31-year-old male diagnosed with refractory glaucoma which is treated with Ahmed valve implantation, placing the tube in the posterior chamber. 72 hours after surgery the patient shows a hyphema that occupies 1/3 of the anterior chamber (AC) and a flat AC grade I (Spaeth classification). Surgical treatment is performed to reform the AC with the injection of 2,3% sodium hyaluronate (Healon®5) and sulfur hexafluoride (SF6) stabilizing the AC after 24 hours. Discussion: The use of sodium hyaluronate, gases or a combination of both has been proposed for the treatment of postoperative AC flattening after trabeculectomy, but we have no information of its use in flat anterior chambers after an Ahmed valve implantation. The objective of the gas is to obtain a mechanic haemostasis and to deepen the AC until the aqueous substitutes it gradually, and the objective of the viscoelastic is to protect the corneal endothelium and to reduce the gas outflow through the tube. The use of Healon®5 and SF6 can be a fast, safe and effective alternative treatment for this adverse event, instead of other classical treatment options like medical treatment or gas injection.
