白內障摘除聯(lián)合房角分離術在疑難閉角型青光眼應用的臨床觀察
[Abstract]:Objective: to observe the clinical effect of phacoemulsification and intraocular lens implantation combined with mechanical atrial angle separation in the treatment of difficult angle closure glaucoma with out of control intraocular pressure after trabeculectomy. Methods: this study was a retrospective, self-controlled study. Patient selection: from April 2015 to August 2016, a total of 12 patients (14 eyes) with complicated angle closure glaucoma complicated with cataract after trabeculectomy and trabeculectomy were collected. Male 2 cases (2 eyes), female 10 cases (12 eyes), age 56 to 85 years old, mean (69.58 鹵8.58) years old. All the patients were in accordance with the diagnostic criteria of angle closure glaucoma. The eyes had a history of trabeculectomy and had different degrees of optic nerve damage and visual field defect. The conglutination of peripheral angle was 270degrees by angle endoscopy, and the angle of UBM rounds was closed or narrowed in varying degrees. The anterior chamber is shallow. Intraocular pressure 21mm Hg or 21mm Hg. after intraocular pressure lowering No contraindication, no other eye diseases. The lowest corrected visual acuity before operation was HM/50cm, and the best corrected visual acuity was 0.4, with different degree of lens opacity. All cases were performed phacoemulsification cataract extraction and intraocular lens implantation by the same machine. Mechanical atrial angle separation was performed simultaneously. Pupil diameter was larger than that of 5mm. Intraocular pressure (IOP) was observed 1 day, 7 days, 1 month, 3 months and 6 months before operation, visual acuity 1 month after operation, open range of anterior chamber angle (degree) and depth of central anterior chamber before operation and 1 month after operation. The complications during and after operation were also recorded. The mean IOP of 14 eyes was (23.3 鹵4.1) before operation, and the mean IOP of 14 eyes was (17.2 鹵4.6) (17.9 鹵2.1), (16.8 鹵1.4) on the first day, 1 week, 1 month, 3 months and 6 months after operation. (15. 7 鹵1. 8), (鹵15. 8 鹵1. 5), using paired t test, p value was 0. 05, there was significant difference between before and after 1 month, the range of angle adhesion was obviously reduced. UBM showed that the depth of central anterior chamber was significantly deeper than that before operation (P0.05), there was statistical significance. 14 eyes (100%) 1 month after surgery corrected visual acuity improved in varying degrees. There was significant difference in the best corrected visual acuity before and after 1 month (Wilcoxon sign rank sum test; ZHS-5.43P 0.05), which was statistically significant. Only 1 case had hyphema and 2 cases had corneal edema. Follow-up for 6 months showed no serious complications and intraocular pressure was within normal range. Results: phacoemulsification and intraocular lens implantation combined with mechanical atrial angle separation were effective for patients with uncontrollable IOP after trabeculectomy. IOP was well controlled and visual acuity was recovered. The depth of anterior chamber was deeper, the degree of angle opening was enlarged, and the complications were less. It provides a new way of treatment for angle-closure glaucoma patients who have lost control of intraocular pressure after anti-cyanosis, and is worth popularizing in clinic.
