吲哚青绿眼底血管造影在常见眼底病诊断中的应用

吲哚青绿眼底血管造影（ICGA）在1970年用于眼底造影。相较于传统的荧光素钠造影（FFA）能更好的反应脉络膜层血液循环的状况,可作为诊断脉络膜病变的重要辅助手段。通过动态观察ICGA可以明确病变部位、分类,指导治疗,评估预后等。本文就吲哚青绿目前在眼科临床上的应用作一综述。     

努力提高眼底血管造影的临床释义水平

眼底血管造影主要包括以荧光素钠为染料、波长 490 nm的蓝色可见光为激发光的荧光素眼底血管造影 (fundus fluo-rescein angiography,FFA)及以吲哚青绿 (indocyanine green,ICG)为染料、波长 80 5 nm的近红外光为激发光的吲哚青绿血管造影 (indocyanine green angioraphy,ICGA)。 FFA对视网膜血管疾病和视网膜色素上皮 (retinal pigment epithelium,RPE)病变显示了其重要的临床价值 ,但对脉络膜疾病的观察却难以令人满意 ,而 ICGA则能较好地显示脉络膜相关疾病的病理生理改变及其血循环特征。我国于 70年代开始进行 FFA的研究 ,但…     

应用荧光素吲哚青绿同步眼底造影对中心性浆液性视网膜病变眼底微循改变的观察

目的 通过分析中心性浆液性视网膜病变(central serous chorioretinopathy,CSC)患者的视网膜-脉络膜同步造影特点.探究其发病机理.方法 应用海德堡造影系统HRA2对26例(28眼)患者进行视网膜.脉络膜同步造影,并对结果进行分析.结果 眼底照相:黄斑区神经上皮浆液性脱离,2眼伴色素上皮脱离.荧光素眼底血管造影(fundus fluoreseein angiography,FFA)检查显示:28眼均有视网膜色素上皮(retinal pigment epithelium,RPE)渗漏,2眼伴色素上皮脱离.吲哚青绿血管造影(indocyanine green angiography,ICGA)检查显示:早期28眼均有区域性脉络膜血管扩张充血、脉络膜高通透性,24眼区域性脉络膜血管充盈迟缓,其余4眼脉络膜充盈大致正常;中、晚期23眼RPE渗漏处有脉络膜血管的高荧光扩散,5眼表现为高荧光点:18眼ICGA揭示的病灶要比FFA多.10眼可见RPE色素脱失.1例女性CSC患者激光光凝FFA渗漏点后1个月,FFA见黄斑下液体吸收、RPE渗漏点封闭,而ICGA仍见脉络膜活动性渗漏点.结论 CSC的发生可能是由于脉络膜循环紊乱及脉络膜血管通透性增高导致RPE损害引起.激光能改善RPE渗漏,但对脉络膜病变本身没有作用.

Indocyanine green angiographic features of choroidal rupture and choroidal vascular injury after contusion ocular injury

PURPOSE: To report features of choroidal rupture and choroidal vascular injury after contusion ocular injury on indocyanine green angiography. METHODS: In a prospective study, nine patients (nine eyes) with choroidal rupture after ocular contusion underwent initial fluorescein angiography and indocyanine green angiography within 19 days after trauma. Eyes that had a distinct abnormality of the retinal pigment epithelium were excluded from this study. Subtraction indocyanine green angiography was also performed. Follow-up fluorescein angiographic and indocyanine green angiographic findings were also studied. RESULTS: Initial ophthalmoscopic examination revealed subretinal hemorrhage in all nine eyes. In five of the nine eyes, choroidal rupture was not seen on initial ophthalmoscopic or fluorescein angiographic examination because it was hidden beneath the subretinal hemorrhage, but it was detected on subsequent examinations. In the remaining four eyes, choroidal rupture was observed by ophthalmoscopy at the time of initial examination, and these eyes exhibited hyperfluorescent streaks on fluorescein angiography in the region of the subretinal hemorrhage. On initial indocyanine green angiography of all nine eyes, observed hypofluorescent streaks became more obvious with time. For each eye, there were more hypofluorescent streaks on indocyanine green angiography than hyperfluorescent streaks on fluorescein angiography. In one eye, the location of indocyanine green leakage nearly coincided with the location of a hyperfluorescent streak on fluorescein angiography. In this case, crescentic streaks of hypofluorescence were seen on the temporal side of the subretinal hemorrhage on indocyanine green angiography, although choroidal rupture was not observed in that region by ophthalmoscopy or fluorescein angiography. In two of the nine eyes, indocyanine green angiography and the subtraction technique demonstrated disturbance of flow into choroidal vessels, especially at the choroidal rupture site. CONCLUSION: After ocular contusion injury, various features of choroidal rupture and choroidal vascular injury were observed on indocyanine green angiography. This technique may contribute to the diagnosis of choroidal rupture and to the understanding of the clinical course after injury.

Indocyanine green angiographic findings in 3 patients with traumatic hypotony maculopathy

PURPOSE: Little is known about the choroidal circulation in human eyes with ocular hypotony. Recently, indocyanine green angiography (IA) became a useful method for examining choroidal circulation. The present study using IA was designed to determine choroidal circulatory disturbances in patients with traumatic hypotony maculopathy. METHODS: Indocyanine green angiography was performed on 3 consecutive patients (3 eyes) with traumatic hypotony. One patient underwent IA using an infrared fundus camera only during the hypotony stage. The other 2 patients underwent IA using a scanning laser ophthalmoscope before and after recovery of intraocular pressure (IOP). RESULTS: During the hypotony stage, IA revealed multiple hypofluorescent spots in many parts of the fundus, sector hypofluorescent areas, dilatation, and tortuosity of the choroidal vessels in the posterior pole. These findings had not been detected by fluorescein angiography. After surgical treatment, IOP returned to the normal range and visual acuity improved. Indocyanine green angiography showed improvement of the sector hypofluorescent areas, and dilatation and tortuosity of choroidal vessels in the posterior pole. However, most of the hypofluorescent spots and regional delay of choroidal filling remained. CONCLUSIONS: Indocyanine green angiography revealed that choroidal circulatory disturbances occurred during the hypotony stage and that some remained during the recovery stage.
