Clinical observation of regulating intraocular pressure of glaucoma after trabeculectomy with laser cutting off scleral suture

Objective To evaluate the method and efficacy of regulating intraocular pressure of glaucoma with laser cutting off scleral suture after trabeculectomy.Methods Postoperative normal depth of anterior chamber after trabeculectomy was obtained with close suture scleral flap.The contact stitches microscope by 532 laser cutting scleral sutures were used according to the postoperative intraocular pressure and appropriate massage was performed to increase filtration for regulating intraocular pressure.Results Fifty trabeculectomy cases without postoperative shallow anterior chamber and 18 eyes after the implementation of laser disconnected scleral suture combined with moderate massage,which did cut off a suture on 14 eyes and two stitches on 4 eyes,followed-up for half a year that lOP of 39 eyes was 8-20mmHg,5 eyes with 21-25 mmHg and an eye with 26-40 mmHg.The main complication:a case with shallow anterior chamber with choroidal detachment by the laser cutting off the two sutures.Conclusions To tightly suture scleral flap during the glaucoma trabeculectomy and regulate intraocular pressure combining with laser cutting string after trabeculectomy,can effectively avoid the occurrence of shallow anterior chamber and other postoperative complications,and access to the ideal postoperative course and surgical effect.
