摘  要:目的比较吲哚青绿介导的光栓疗法(Indocyanine green—medicated photothrombosis,IMP)与光动力疗法(PDT)治疗慢性中心性浆液性视网膜脉络膜病变(Centralserouschorioretinopathy,CSC)疗效。方法对比分析两组共19例22只眼慢性CSC患者分别进行IMP与PDT治疗后1个月,3个月的矫正视力(BCVA),眼底彩色照相,眼底荧光血管造影(FFA)与光学断层相干扫描(OCT)。其中IMP治疗10例11眼,PDT治疗9例11只眼。结果IMP与PDT两组患者治疗后1、3月矫正视力比较,PDT治疗组治疗后1、3月视力提高8例9只眼(90%),视力不变1例1只眼(10%),无视力下降病例;IMP治疗组治疗后视力1月提高8例8只眼(72.7%),治疗后3月1例1只眼视力下降。治疗后1月两组矫正视力比较差异没有统计学意义Х^2=0.11,P〉0.05)。治疗后3月比较差异也没有统计学意义。(Х^2=0.02,P〉0.05)。PDT与IMP治疗后黄斑视网膜厚度比较,PDT组治疗前黄斑视网膜厚度(408±57.1)μm与治疗后3月黄斑视网膜厚度(143.9±43.6)μm比较差异有统计学意义(t=7.06,P〈0.05)。IMP组治疗前黄斑视网膜厚度(397.2±523)μm,与治疗后3月黄斑视网膜厚度(161.24±47.2)μm比较差异有统计学意义(t=-5.0,P〈0.05)。治疗后三月PDT与IMP组黄斑视网膜厚度比较差异没有统计学意义(t=0.83,P〉0.05)。PDT与IMP治疗后3月黄斑区RPE渗漏观察,治疗后3月两组FFA显示黄斑区RPE渗漏灶均消退。照射部位存在不同程度的RPE窗样缺损或轻微荧光染色。6月后FFA随诊发现IMP治疗组2例2只眼黄斑区原照射部位的RPE重新渗漏。结论PDT改变治疗参数如减半光敏剂用量,以减少对脉络膜血液循环的影响的疗法可有效安全的治疗慢性CSC,本课题研究表明IMP治疗慢性CSC的短期疗效比较好,安全性高。而治疗费用远低于PDT,是一种较实用治Objective compare the clinical efficacy ofphotodynamic and indoeyanine green-medicated photothrombosis (IMP) for chronic central serous ehorioretinapathy (CSC).Methods Nineteen cases (22 eyes) with chronic CSC were divided into PDT and IMP groups.Ten cases (11 eyes) were treated with IMP and 9 eases ( 10 eyes) with PDT.BCVA, FFA, OCT and fundus color photograph were evaluated before and after treatment within one or three months.Results Visual acuity increases of PDT group and/MP group followed up 1 to 3 months had no difference (Х^2=0.11, P〉 0.05; Х^2=-0.02, P〉 0.05 ), so as the thickness of macular retina between PDT groups and IMP groups (t=-0.83, P〉0.05) followed up for 3 months, both of the groups FFA showed cessation or reduction of fluorescein from macular RPE followed up for 3 months.Two eyes of IMP groups, FFA showed macular RPE releakage in the pre-treated area.Conclusions The effect of PDT with reduction dosage of visudyne for treatment of chronic CSC is safe and better.The short-term effect of IMP for treatment of chronic CSC is same as PDT; while the cost of IMP is less expensive than PDT.However,more cases study and long term follow-up to evaluate IMP in treating chronic CSC is needed.
