Abstract: Objective To probe into the treatment method of filter channel obstruction after trabeculectomy. Methods Filter channel obstruction occurred in 25 eyes within one month after trabeculectomy,and they were retrospectively analyzed. According to different parts of obstruction,they were divided into three types namely inner obstruction, middle obstruction and outer obstruction. Patients with inner ob-struction were given miosis, separation of the anterior synechia, and expansion of peripheral iris incision when necessary. Patienrts with mid-dle obstruction were given reconstruction of the trabecular incision. Patienrts with outer obstruction were given conjunctiva or sclera flap dis-section within 1 month afer trabeculectomy. Results Postoperative IOP ( intraocular pressure) decreased significantly compared with preop-erative IOP. The IOP stabilized at 13~21 mmHg in the fallowing 6~12 months after operation. Conclusion Taking appropriate measures could restore the filtration function within one month after trabeculectomy when the incision adhesion was not very close.
