目的:观察中心性渗出性脉络膜视网膜炎(choroidal neovascularization,CEC)的眼底荧光血管造影(fundus fluorescein angiography,FFA)的特征。
方法:选取江苏省中医院眼科2011-01/2012-12门诊临床诊断为CEC患者45例,对45例49眼应用海德堡共焦激光扫描眼底造影系统(HRA)进行FFA检查,并对结果进行分析。
结果:CEC 30眼于动脉前期或动脉期可见来自脉络膜的视网膜下新生血管显影,迅速发生渗漏,随造影过程扩大、增强,病灶处呈现一团强荧光斑,到造影后期仍持续不退,周围出血在强荧光灶周围有环形、片状或弧形的遮挡荧光,视网膜水肿在强荧光灶周围见与水肿一致的低荧光,为活动期(进行期)病变; 10眼可见病灶周围脱色素区强荧光,渗漏较少,不扩大,为恢复期(退行期)病变; 9眼在动脉早期见与病灶一致的强荧光,渐增强,无渗漏,不扩大,可见瘢痕与色素遮挡荧光,后期荧光着染,或可见环形透见荧光,为瘢痕期(静止期)病变。
结论:FFA可提高CEC的诊断率,减少误诊和漏诊,为明确诊断提供有效的依据,并可指导临床治疗。

AIM: To observe the characteristics of fundus fluorescein angiography(FFA)of central exudative chorioretinitis(CEC).
METHODS:Totally 45 patients with central exudative chorioretinitis from Department of Ophthalnolgy, Jiangsu Provincial Hospital of Traditional Chinese Medicine, from January 2011 to December 2012 were chosen. Fundus fluorescein angiography(FFA)was performed on 49 eyes of 45 patients with Heidelberg retina angiography(HRA), and the results were analyzed.
RESULTS:Retinal neovascularization from choroidal was visible in 30 eyes of patients with central exudative chorioretinitis in the early period of artery arterial or at artery arterial period, leakage happened quickly, along with the imaging process to expand enhancement. There was a strong fluorescence spot in a mass lesion, and to late period, the imaging was still persistent. Bleeding around in strong fluorescence covered oven around ring plate or arc barrier fluorescence. Retinal edema was visible in strong fluorescence and the same at low fluorescence. It was lesions of active stage. Strong fluorescence was visible in 10 eyes of patients around the lesions of depigmentation, leakage less, not expanding. It was lesions of convalescence. Strong fluorescence in the early period of artery arterial or at artery arterial period was visible in 9 eyes of patients, gradually enhance, no leakage, not expanding, was visible to blocked fluorescence cause by scar and pigment. Later the fluorescent dye was visible to window defect hyperfluorescence. It was lesions of scar period.
CONCLUSION:FFA can improve the diagnosis rate of central exudative chorioretinitis and decrease the misdiagnosis and missed diagnosis rate. In addition, it can provide effective basis for diagnosis and guide the clinical treatment.
