Analysis Of Risk Factors Of Shallow Anterior Chamber After Glaucoma Filtration Surgery

Purpose：一、Analyzed the epidemiological characteristics of hospitalized patientswith glaucoma, provide reference for prevention, treatment and clinical work.二、Analysis the incidence of hospital glaucoma filtration surgery shallowanterior chamber,summary the risk factors of shallow anterior chamber andguide future clinical work.Method:一、Retrospective analysis May1,2008～May31,2013in our hospital’sclinical data of glaucoma patients,analyze its clinical epidemiologicalcharacteristics.二、Retrospective analysis May1,2008～May31,2013in our hospitalglaucoma patients to understand the ratios of shallow anterior chamber afterglaucoma filtration surgery.Regression correlation between age,type of glaucoma, preoperative intra-ocular pressure (IOP) and other factors andshallow anterior chamber.Result:一、The glaucoma types of hospitalized patientsThat had906cases of glaucoma patients admitted to hospital, of which629cases of primary glaucoma (69.43%);272cases (30.02%) cases of secondaryglaucoma (SG);5cases(0.55%) developmental glaucoma.二、Surgical and postoperative occurrence of shallow anterior chamberModified trabeculectomy of shallow anterior chamber after surgeryincidence12.80%.Modified trabeculectomy with mitomycin C (MMC)treatment of shallow anterior chamber after surgery incidence17.36%.Modifiedtrabeculectomy combined lens extraction with intraocular lens implantationshallow anterior chamber10.42%.Modified trabeculectomy combined lensextraction with intraocular lens implantation and anterior vitrectomy shallowanterior chamber rate of12.5%.By X2test shows that the use of MMC andshallow anterior chamber after no significant correlation. X2test results showedimprovement after lens extraction trabeculectomy combined incidence ofshallow anterior chamber after surgery lower than modified trabeculectomylow.三、The clinical relevance of the common risk factors associated with theoccurrence of shallow anterior chamber afterLogistic regression analysis showed that age>60years, diabetes,admission IOP>50mmHg,preoperative IOP>30mmHg,axial length<21.00mm,anteriorchamber depth≤1.75mm,was significantly associated with the occurrence ofshallow anterior chamber.Further study the correlation between hypertensionand coronary heart disease.Conclusion:1、Hospitalized patients with primary glaucoma main types of glaucoma.Modified trabeculectomy combined lens extraction shallow anterior chamberintraocular lens implantation rates lower than the modified trabeculectomy.2、Regression analysis showed significant correlation of age>60years,diabetes, admission IOP>50mmHg, preoperative IOP>30mmHg, axial length<21.00mm, anterior chamber depth≤1.75mm, with a shallow anteriorchamber occurred. Intraoperative mitomycin C use and the occurrence ofshallow anterior chamber after no significant correlation. Given the age of>60years is a risk factors of shallow anterior chamber, improved resectioncombined cataract extraction and intraocular lens implantation, shallow anteriorchamber modified trabeculectomy rate than lower,in the future the age>60years concurrent caract patients the promotion of the procedure,in order toreduce the incidence of shallow anterior chamber.3This study restricted by retrospective medical records could not berecognized as risk factors for the crystal thickness, angle, etc. into the state set ofrisk factors is not perfect, the need for further clinical studies.
