摘要

·AIM: To evaluate the difference in angle parameters and clinical outcome following phacoemulsification and combined phacotrabeculectomy in patients with acute primary angle closure(APAC) using ultrasound biomicroscopy(UBM).·METHODS: Patients(n =23, 31 eyes) were randomized to receive phacoemulsification or combined phacotrabeculectomy(n =24, 31 eyes). Best-corrected visual acuity(BCVA), intraocular pressure(IOP), the main complications following surgery, and indentation gonioscopy and angle parameters measured using UBM were documented preoperatively and postoperatively.· RESULTS: The improvement in BCVA in the phacoemulsification group was significantly greater than in the combined group(P 【0.05). IOP in the phacoemulsification group was slightly higher than in the combined group following 1wk of follow-up(P 【0.05),whereas there was no significant difference between the two groups at the latter follow-up(P 】0.05).Phacoemulsification alone resulted in a slight increase in the trabecular ciliary processes distance compared with the combined surgery(P 【0.05), whereas the other angle parameters showed no significant difference between the groups. Complications in combined group were greater than phacoemulsification only group.·CONCLUSION: Both surgeries effectively opened the drainage angle and deepened the anterior chamber, and IOP was well controlled postoperatively. However,phacoemulsification showed better efficacy in improving visual function and showed reduced complications following surgery.
