Releasable sutures are used in glaucoma filtering surgery to titrate the degree of aqueous humor outflow to avoid early postoperative hypotony and its associated complications.1 The technique involves externalizing scleral flap sutures through the peripheral cornea, which allows for their removal at a later time when increased aqueous humor outflow is desired. We report, to our knowledge, the first case of postoperative endophthalmitis following trabeculectomy with releasable sutures.
Report of a Case.
A 67-year-old white man with primary openangle glaucoma had a trabeculectomy with intraoperative application of mitomycin C (0.3 mg/mL, 3-minute exposure) in the right eye. The scleral flap was secured with 2 releasable sutures that were externalized through the cornea, per the technique of Cohen and Osher.2 The free corneal ends of the sutures were buried so that only a small loop of suture remained exposed. Postoperatively, the intraocular pressure stabilized at 4 to 8 mm
