목적 : To evaluate the technique of vitreous tap using micro-incisional single-port transconjunctival limited pars plana vitrectomy for management of acute angle-closure glaucoma.
방법 : A retrospective study included 26 patients who underwent phacoemulsification diagnosed with acute angle-closure glaucoma. Among them, 16 patients (16 eyes) underwent phacoemulsification alone, 10 patients (10 eyes) underwent combined limited vitrectomy and phacoemulsification. Then we compared intraocular pressure, anterior chamber angle, anterior chamber depth, central corneal thickness and corneal endothelial cell count before and after surgery, and effective phacoemulsification time during cataract surgery.
결과 : Effective phacoemulsification time was shorter in the combined surgery group than in the single surgery group (p =0.040). There was no statistically significant difference in intraocular pressure and best-corrected visual acuity between the two groups postoperatively. At 6 months postoperatively, there was no difference in the anterior chamber angle, anterior chamber depth, and central corneal thickness between two groups, but corneal endothelial cell count was higher in the combined surgery group than in the single surgery group. (p = 0.046).
결론 : Combined micro-incisional single-port transconjunctival limited pars plana vitrectomy and phacoemulsification are more effective and safer than phacoemulsification alone because of less operation time and fewer complications for management of acute angle-closure glaucoma.
