Abstract
To investigate the clinical efficacy of cyclocryotherapy combined trabeculectomy and single cyclocryotherapy for neovascular glaucoma (NVG). <br> ●METHODS:Totally 82 patients with NVG from February 2012 to June 2013 in our hospital were selected and randomly divided into observation group and control group, each 41 cases. Patients in control group were given single cyclocrytherapy, and patients in observation group were given cyclocryotherapy combined trabeculectomy. The visual acuity, intraocular pressure and postoperative complications of two groups were observed. <br> ●RESULTS: After postoperative six months, the improvement rate of visual acuity in observation group was 61. 0%, which was significantly higher than that of control group ( 41. 5%), the difference was statistically significant (χ2 = 3. 843, P = 0. 018). lntraocular pressure of observation group was significantly lower than that of control group, the difference was statistically significant (P<0. 05). The complication rates ( eye pain, hyphema, and corneal edema) of observation group were 9. 8%, 12. 2%, and 9. 8%, which were significantly lower than that of control group (51. 2%, 60. 9%, and 48. 8%), the difference was statistically significant (χ2 = 7. 594,P= 0. 007;χ2 = 9. 276,P= 0. 000;χ2 = 6. 835,P = 0. 013). The difference of two groups was not statistically significant on complications of conjunctival edema, anterior chamber exudation, shallow anterior chamber, and eyeball atrophy (P>0. 05). <br> ●CONCLUSlON: Compared with single cyclocryotherapy, cyclocryotherapy combined trabeculectomy has advantages of low intraocular pressure, less postoperative complications, and high success rate, so it is worthy of promotion.关键词
