吲哚青绿脉络膜血管造影Ⅰ.基本情况   总被引:5,自引:2,他引:3  
眼底镜的发明和眼底荧光血管造影(fundus fluorescein angiography,FFA)的引入,使得对眼底结构和功能的认识及很多眼底病的诊治向前迈了一大步.但由于脉络膜血管被色素上皮及自身色素遮挡,观察困难,对血管构筑和血流动力学及在眼病中的地位和作用了解不多.以前对脉络膜循环的了解多基于离体铺版或血管铸型研究或FFA,这些研究在一定程度上提示了脉络膜血管的构筑,但临床上却需要一种能直接观察循环的动态方法以解决临床实际问题.70年代以来以Flower为代表的研究者们引入吲哚青绿脉络膜血管造影(indocyanine green choroidal angiography,ICGCA)[1]使人们能更清楚而直观地了解脉络膜血循环动态情况,随着技术的不断进步和经验的积累,ICGCA将逐步被人们所认识,ICGCA在一些发达国家已较多应用于临床.兹将ICGCA的基本情况、临床应用及技术新进展分三篇介绍。 (中华眼底病杂志,1994,10:253-255)  相似文献

Objective: To observe the characteristics of indocyanine green angiography (ICGA) in exudative age-related macular degeneration (AMD).Methods: Thirty-one cases (39 eyes) were diagnosed as exudative AMD by ocular examination, fundus color photography, fundus fluorescein angiography (FFA) and ICGA. Their ages ranged from 50 to 82 years and visual acuities from FC/30cm to 0. 7. We analyzed and compared the characteristics of ICGA and FFA in these patients. Results: Of 26 eyes with occult choroidal neovascularization (CNV) by FFA, 15 (57. 7% ) had classic CNV by ICGA. Of 4 eyes with serous retinal pigment epithelial detachment (FED) without CNV by FFA, 1 had serous FED with classic CNV by ICGA. The hyperfluorescence of the scar staining was detecfed by ICGA. Conclusion ? ICGA adds clinically useful information and is an important adjunct in the evaluation, classification, and laser treatment of patients with occult CNV in AMD.

PurposeTo compare patterns of choroidal venous drainage in eyes with pachychoroid disease to those of healthy subjects using ultra-widefield indocyanine green angiography (UWF ICGA).MethodsPatients with pachychoroid disease and healthy controls were recruited at two referral centers. UWF ICGA images were used to evaluate the proportion of the postequatorial fundus drained by major vortex vein systems in each quadrant and to study the incidence and topography of choroidal vascular hyperpermeability (CVH) and intervortex venous anastomoses. Widefield swept-source optical coherence tomography (SS-OCT) was used to evaluate choroidal thickness at the posterior pole in eyes with pachychoroid disease.ResultsFifty-two pachychoroid eyes and 26 healthy eyes were evaluated. Eyes with pachychoroid disease showed a significant within-subject variance in the proportion of the postequatorial fundus drained by each vortex vein system (range, 4.1%–48.1%; P < 0.0001) that was not seen in controls (range, 17.3%–31.7%; P = 0.11). CVH was present in all pachychoroid disease eyes and three of 26 controls. Intervortex venous anastomoses were present in 46 of 52 pachychoroid disease eyes and nine of 26 control eyes. Vortex vein systems with large drainage areas showed greater density of CVH spots. SS-OCT demonstrated asymmetric choroidal drainage in the macula of 59% of pachychoroid eyes. CVH and intervortex venous anastomoses were more prominent in areas showing maximal choroidal thickness.ConclusionsIn eyes with pachychoroid disease, imbalanced choroidal venous drainage with congestion of specific vortex vein systems may contribute to a state of choroidal venous insufficiency characterized by regional choroidal thickening, CVH and remodeling of venous drainage routes.  相似文献

Purpose:To study the clinicopathological change on "Multiple Evanescent White-dot Syndrome (MEWDS)" through fundus angiogrphy analyses.Methods:Examing the case with fluorescein angiography (FFA) and indocyanine green angiography(ICGA), visual field and following up for 15 months.Results:There exist multiple white dots in the fundus photo and angiography. The changes on ICGA maintain longer than fundus photo and FFA. Papille may be edematous and macula could present with special hypofluorescent flecks.Conclusions:MEWDS has specific angiographic features. Its pathological changes involve deep retinal pigment epithelium(RPE) as well as choroidal capillaries. The prognosis of the visual acuity for MEWDS is very good.

Purpose To analyze the histopathology of polypoidal choroidal vasculopathy (PCV) and choroidal neovascularization (CNV) developing from PCV, the authors evaluated correlations between pathological findings and the findings of preoperative indocyanine green angiography (IA).Methods Two specimens were obtained during CNV excision associated with PCV. PCV tissue was excised with the CNV. The specimens were examined by light microscopy.Results In one case, IA revealed polypoidal lesions exhibiting hyperfluorescence in both the early and the late phase, and in the affected area, abnormally dilated vessels were identified histologically underneath relatively healthy retinal pigment epithelium (RPE). In the other case, the polypoidal lesions seen on IA showed early hyperfluorescence and late isofluorescence, and dilated vessels were observed under the RPE; perivascular amorphous material was present. The RPE adhered to the side of the choroid, and there was CNV under the neurosensory retina in both cases. The CNV had numerous vascular lumens, was not surrounded by the RPE, and exhibited few fibrous components.Conclusions IA findings vary depending on the condition of the RPE located above the PCV and the extent of amorphous material around the PCV.

Purpose:To report a case of a macular hole in a female adult with bilateral Coats disease.Methods:The fundus photograph, fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA) were performed in two eyes, and observed theirs characters.Results:Fundus photograph showed massive yellowish-white exudation in the temporal midperiphery of both eyes, but the degree was slighter in the right eye. There was 1/3 DD macular hole in left eye. FFA revealed general dilatation of capillaries, multiple aneurysms, and tortuous and closure of vessels in superotemporal midperiphery in both eyes, but the degree was slighter in the right eye. There was a one-third DD round transmitted fluorescence according the macula hole. ICGA revealed that hyperfluorescence of aneurysms in superotemporal midperiphery, the images of aneurysms were more clearly than in FFA. There was a 2/3 DD hypoflurescence of macula in the late phase of angiography.Conclusions: FFA and ICGA have respective advantage in revealing vas  相似文献

Purpose: To determine the role of indocyanine green angiogaphy (ICGA) in the prediction of the development of choroidal neovascularization (CNV). Methods: We reviewed the ICG angiograms of 124 patients with newly diagnosed unilateral occult CNV secondary to age-related macular degeneration (AMD) in whom the fellow eye had only drusen by biomicroscopy and fluorescein angiography. Follow-up data of at least 12 months were obtained in all eyes. Results: 113 fellow eyes had a normal ICG study, while 11 fellow eyes revealed plaque-like late hyperfluorescence. During an average follow-up time of 18.2 months exudative AMD developed in 7 of 11 eyes with late hyperfluorescence on ICGA and in 6 of 113 with a normal ICGA study. Conclusion: ICGA may help to predict which fellow eyes are at higher risk of developing future exudative changes.
