光学相干断层扫描在光动力疗法治疗中心性渗出性脉络膜视网膜病变的应用

目的 探讨光学相干断层扫描(optical coherence tomography,OCT)对光动力疗法(photodynamic terapy PDT)治疗中心性渗出性脉络膜视网膜病变(central exudative chorioretinopathy,CEC)脉络膜新生血管(choroidal neovascularization,CNV)的临床应用价值.方法 对CEC患者45例(46只眼)进行光学相干断层扫描,荧光素眼底血管造影(fundus fluorescein angiography,FFA),吲哚青绿脉络膜血管造影(indocyanine green angiography,ICGA)检查.根据FFA,ICGA和OCT检查结果,明确CNV位置、范围和大小.PDT治疗按维替泊芬PDT治疗(VIP)研究组的方法 进行.并对其疗效进行评价.结果 光动力疗法(PDT)治疗后视力提高者13只眼,占28.26%;视力稳定不变者22只眼,占47.82%;视力下降者11只眼,占23.92%.OCT复查结果 为14只眼(3044%)黄斑水肿消失;18只眼(39.13%)黄斑水肿减轻;10只眼(21.73%)无变化;4只眼(8.7%)黄斑冰肿加重.CNV消失15只眼(32.61%),CNV缩小24只眼(52.17%),CNV无变化4只眼(8.7%),CNV增大3只眼(6.52%).治疗后视网膜厚度明显变薄(P<0.01).黄斑中心凹视网膜神经上皮层厚度与视力呈负相关(r=0.4963,P<0.01).结论 OCT可客观、精确地显示CNV的位置、大小、范围及视网膜水肿的变化程度,对指导光动力疗法(PDT)治疗中心性渗出性脉络膜视网膜病变(CEC)脉络膜新生血管(CNV)的疗效评价有着重要价值.

Abstract：

Objective To verify the applicable significance of optical coherence tomography (OCT)photodynamic therapy (PDT) for central exudative chorioretinopathy (CEC) choroidal neovascularization (CNV). Methods Forty-five cases (46 eyes) of central exudative chorioretinopathy (CEC) were managed with PDT. Before and post-treatment, all cases underwent OCT, fiuorescein angiography (FFA) and indocyanine green angiography (ICGA). PDT treatment was in accordance with the PDT verteporfin therapy (VIP) Study Group methods. Results The visual acuities of last visit were compared with those before the treatment. The visual acuity was improved in 13eyes (28.26%), unchanged in 22 eyes (47.82%), and declined in 11 eyes (23.92%). OCT was re-done and compared with OCT images before PDT treatment. The macular edema was disappeared in 14 eyes (30.44%), decreased in 18 eyes (39.13%), unchanged in 10 eyes (21.73%), and increased in 4 eyes (8.7%). CNV was disappeared or decreased in 39 eyes (84.78%), unchanged in 4 eyes (8.7%),and progressed in 3 eyes (6.52%). The retinal thickness was decreased obviously (P ＜0.001). The statistical analysis showed there was a negative correlation between the thickness of fovea and visual acuity (r =0.4963, P =0.001). Conclusions OCT can precisely show the location, size and changes of retinal thickness and has an important significance in PDT treatment for CEC.
