  • Title: Trabeculectomy with releasable sutures.
    Author: Kolker AE, Kass MA, Rait JL.
    Journal: Trans Am Ophthalmol Soc; 1993; 91():131-41; discussion 141-5. PubMed ID: 8140688.
    Abstract:
    We attempted to reduce some of the postoperative complications of trabeculectomy by using releasable scleral flap sutures. This technique allows an initial tight closure of the scleral flap with the option to increase aqueous humor outflow in the early postoperative period. We reviewed our experience with trabeculectomy and releasable sutures in 146 eyes (134 patients) and compared these cases with a prior series of 128 eyes (124 patients) that underwent trabeculectomy with permanent scleral flap sutures. In the control group, 42 eyes (32.8%) had clinically detectable shallowing of the anterior chamber in the postoperative period. In contrast, shallow anterior chamber was noted in 21 eyes (14.4%) in the group with releasable sutures (P = .0003). Flat anterior chamber, defined as iridocorneal touch to the pupil margin, occurred in 11 control eyes (8.6%) but in only 2 eyes (1.4%) with releasable sutures (P = .0078). Surgical intervention to drain suprachoroidal fluid and re-form the anterior chamber was required in eight control eyes (6.2%) but in only one study eye (0.7%) (P = .014). At 1 year of follow-up, the two groups were similar in terms of mean intraocular pressure, the need for ocular hypotensive medications, and failure rate.
