Clinical Effects Of Two Different Operation Ways On Neovascular Glaucoma

Objective: To observe the clinical efficacy of two surgical methods in treatment of new vascular glaucoma in our hospital. Methods: Collected 41 cases of neovascular glaucoma diagnosed in 41 patients from January 2012 to December 2015 in our hospital, and follow-up time ≥ 6Mo, the joint group of 18 cases( underwent intravitreal ranibizumab injection combined with modified trabeculectomy)and the case of the valve implanted 23 patients(Ahmed glaucoma valve implantation), comparing postoperative visual acuity, intraocular pressure and complications.Results: Postoperative visual acuity improved or unchanged, the combined group about 94.44%,valve implant group about 78.26%, the difference was not statistically significant(χ2=1.020,P=0.313). Postoperative intraocular pressure, intraocular pressure changes before and after the glass body cavity medicine injection in joint group were no statistically significant difference(P< 0.05);Joint group in different time points of intraocular pressure, the difference was statistically significant(F=26.199, P<0.001); Compared by twos further, three days after operation, 1 week of intraocular pressure, respectively, and the late compared to the rest of the time point of the intraocular pressure, the difference was statistically significant(P<0.05).Valves implanted groups in different time points of intraocular pressure difference was statistically significant(F=17.323, P<0.001); Compared by twos further, three days after operation, one week late the rest of the time point of intraocular pressure, intraocular pressure and the difference was statistically significant(P<0.05); Postoperative intraocular pressure for 1 and 2months were higher than 3 and 6 months, the difference was statistically significant(P<0.05). Except 1 week, 1 and 2 mo intraocular pressure of joint group began to decrease significantly were lower than the valve implant group, the difference was statistically significant(P<0.05); The rest of the time point has no statistically significant difference(P>0.05).Postoperative complications: the incidence of corneal edema, hyphema and shallow anterior chamber in joint group all lower than that of valve implantation postoperative, the difference was statistically significant(P<0.05). Conclusion: Joint group can be more smooth control of intraocular pressure and protect visual function and reduce postoperative complications and improve the success rate of surgery.
