Clinical observation on releasable sclera flap sutures in trabeculecto-my.

Objective To observe the clinical results of releasable sclera flap sutures in trabeculectomy. Methods In trabeculectomy, a pair of tight releasable suture was made at each side of the sclera flap and about 1 mm of the end was exposed to the cornea surface.5 - 15 days after surgery, the releasable sutures were removed according to the anterior chamber condition.Results In all of the 28 cases (29 eyes) ,no shallow anterior chamber took place in the first 3 days after surgery,5 days after surgery, Ⅰ grade of shallow anterior chamber occurered in 1 eye after sutures were removed, but was recovered to normal with treatment. 15 days after surgery,the intraocular pressure (IOP) was controlled to 8.54 ~ 14.57 mmHg for all of the eyes. Conclusion Releasable sclera flap sutures can effectively accommodate IOP,reduce the occurrence of postoperative shallow anterior chamber and improve surgical successful rate.
