Abstract Objective: To explore the clinical effect of early laser disconnection and needle disconnection for intraocular pressure control after trabeculectomy. Methods: Fifty primary glaucoma patients (50 eyes) were enrolled in the study from August 2014 to February 2017 in the affiliated hospital of Chengde Medical College. All patients accepted complex trabeculectomy. All patients were observed closely after surgery and accepted early needle or laser suture cut if necessary. Subjective symptoms, vision, intraocular pressure and anterior chamber were observed to compare effect of these two disconnection methods for intraocular pressure control after glaucoma surgery. Results: Within one month after surgery, 18 cases accepted laser disconnection (laser group), 19 cases accepted needle disconnection (needle group). To the end of follow-up, 38 cases of all(76%) were successful , 12 cases (24%) were effective. 14 cases (77.78%) in the laser group were successful, 15 cases (78.95%) in needle group were successful, there was no significant difference in the success rate between the two groups (P>0.05).There was no significant difference in scores of subjective symptoms between the two groups before disconnection (P＞0.05). The scores of subjective symptoms in layser group was significantly lower than that in needle group at 1 day after disconnection ,the difference was statistically significant (P <0.05). There was no significant difference in scores of subjective symptoms between the two groups at 3days and7days (P＞0.05).There was no significant difference in best corrected visual acuity and anterior chamber depth in the two groups at 1 week after disconnection compared with before disconnection (P＞0.05). There was significant difference in intraocular pressure at 1 week after disconnection and the last follow-up compared with before disconnection(P＜0.05). Conclusion: Complex trabeculectomy combined with early laser or needle disconnection is safe and effective. Clinicians can choose it appropriately according to hospital and patient conditions.
