BACKGROUND: The indocyanine green (ICG) finger monitoring method is a newly developed noninvasive method for the ICG clearance test. This study was performed to determine its clinical usefulness compared with the conventional blood sampling method. METHODS: The ICG clearance test was performed on 270 patients using both the conventional blood sampling method and the finger monitoring method simultaneously. The plasma disappearance rate of the ICG and the 15-minute retention ratio (ICG R15) were analyzed and compared with the conventional blood sampling method. RESULTS: The plasma disappearance rate using the finger monitoring method was slightly lower than that of the conventional blood sampling method with good correlation (r=0.840, P<0.001). ICG R15 using finger monitoring method was slightly higher than that of the conventional blood sampling method with good correlation (r=0.839, P<0.001). CONCLUSIONS: As there was a good correlation between the conventional blood sampling method and the finger monitoring method, the latter method seemed to be clinically useful due to its convenience and accuracy.

Indocyanine green (ICG) is the most commonly used near-infrared fluorescent (NIRF) dye in clinical practice, and its mediated near-infrared fluorescence imaging technology is gradually applied in clinical practice. It has shown great potential in invasive surgery (MIS) and is expected to become the standard technology for surgical diagnosis and treatment of diseases. The clinical application of ICG fluorescence laparoscopy is reviewed here.

6.Changes of Network Vessels after Photodynamic Therapy in Polypoidal Choroidal Vasculopathy.
Journal of the Korean Ophthalmological Society 2006;47(11):1751-1758
PURPOSE: To evaluate whether the branching vascular network component of polypoidal choroidal vasculopathy (PCV) could be occluded after photodynamic therapy (PDT). METHODS: A retrospective clinical study based upon indocyanine green angiogram was performed in 26 eyes of 26 patients having PCV and treated with PDT. RESULTS: Of the 19 eyes which received a single session of PDT, none showed complete occlusion of the vascular network and 16 (84%) showed, at least in part, a persisting vascular network. Of the 7 eyes which had two session of PDT, 1 (14%) showed complete occlusion of the vascular network, and 3 (43%) showed, at least in part, a persisting vascular network. Changes in the vascular network could not be evaluated with exactness in 6 eyes. Of the 18 eyes achieving clinical improvement after single PDT, 3 had recurrence of hemorrhagic or exudative changes from new polypoidal lesions which originated from the persisting vascular network. CONCLUSIONS: It is difficult to expect complete occlusion of branching vascular network after PDT, which means future recurrence may not be prevented even though occlusion of polyps accompanied with clinical improvement can be achieved with PDT.

PURPOSE: To evaluated the fluorescein and indocyanine green angiographic findings (FAG and ICGA) of each stage in vitelliform macular dystrophy. METHODS: In this study (3 patients, 6 eyes), the stage of macula lesion was classified as follows: stage A (vitelliform), stage B (pseudohypopyon), stage C (scrambled egg), stage D (early cicatricial), and stage E (advanced cicatricial). RESULTS: At stage A, the lesion was hypofluorescent in the early phase and was hyperfluorescent in the late phase of both FAG and ICGA. At stage B, FAG showed hyperfluorescent in the upper portion and hypofluorescent in the lower portion of the lesion. ICGA showed hypofluorescent in the upper portion. However, ICGA showed hypofluorescent in the early and hyperfluorescent in the late phase in the lower portion. At stage C, the lesion was hypofluorescent in the early phase and hyperfluorescent in the late phase of both FAG and ICGA. At stage D, FAG showed hyperfluorescent and ICGA showed hypofluorescent. At stage E, FAG showed central hypofluorescent lesions and a hyperfluorescent ring. While ICGA showed typically hypofluorescent. CONCLUSIONS: The FAG and ICGA findings showed variable patterns according to the evolution of the lesion.

8.Anterior Capsular Staining with a Mixture of Indocyanine Green Dye and Viscoelastic Material.
Journal of the Korean Ophthalmological Society 2002;43(1):47-52
PURPOSE: The authors used a mixture of ICG dye and viscoelastic material to perform continuous curvilinear capsulorhexis (CCC) in white cataract, in order to stain the anterior capsule with the minimal contact with the corneal endothelial cells. METHODS: In 10 eyes with white cataract, CCC was performed under the anterior capsular staining with ICG dye. The ICG solution was prepared by dissolving 25 mg of ICG in 1 mlof an aqueous solvent, which was mixed in 3 ml of balanced salt solution. With a three-way connector, one way was occluded, the other was connected with 1 ml of viscoelastic material, and the third was connected with 4 ml of the prepared ICG solution. One half percent mixture of ICG and viscoelastic material was made by alternate injection. The anterior chamber was filled with viscoelastic material, and then the anterior capsule was stained by slow spread of the prepared ICG mixture between anterior capsule and viscoelastic material. The remains of ICG mixture was removed by infusion and aspiration. The anterior chamber was filled with viscoelastic material again, CCC was performed with cystotome. Corneal edema and anterior chamber reaction was evaluated with slit lamp at 1 day, 1 week and 1 month after surgery. RESULTS: In all cases, CCC was successfully completed under the anterior capsular staining of the desired area with 0.5% ICG dye mixture and there was no contact with the corneal endothelial cells. Mild corneal edema and mild anterior chamber reaction that observed on the 1st postoperative day subsided within 1 week in all cases. CONCLUSIONS: Staining the anterior capsule with 0.5% ICG dye mixture, after the anterior chamber was filled with viscoelastic material, it was helpful to perform CCC in white cataract. Using this technique, we could minimize the contact with the corneal endothelial cells and stain the desired area.

PURPOSE: To compare the outcomes of indocyanine green (ICG) and triamcinolone (TA) assisted internal limiting membrane (ILM) peeling during idiopathic macular hole surgery. METHODS: Fifty-four eyes of 54 patients with idiopathic macular hole underwent pars plana vitrectomy including peeling of the posterior cortical hyaloid and peeling of the internal limiting membrane. For enhanced visualization of ILM, ICG was used in 25 eyes and TA in the remaining 29 eyes. Postoperative visual acuity was measured and OCT was performed. RESULTS: Anatomical closure was achieved in 25 eyes (100%) in ICG group and 28 eyes (97%) in TA group, Best corrected visual acuity improvement by > or =2 lines was in 15 eyes (60%) in ICG group and 18 eyes (62%) in TA group. Postoperative visual improvement rates by > or =20/50 were 10 eyes (40%) in ICG group and 9 eyes (31%) in TA group. CONCLUSIONS: Peeling of the internal limiting membrane using triamcinolone and indocyanine green was safe and effective for anatomic and functional success in idiopathic macular hole surgery. Further studies of the toxicity of TA, ICG and the result of internal limiting membrane peeling is needed.

Journal of the Korean Ophthalmological Society 1998;39(2):354-361
We examined three patients with multiple evanescent white dot syndrome(MEWDS) using confocal laser scanning indocyanine green angiography(ICGA), and observed two types of hypofluorescent lesion which were very characteristic and diagnostic by themselves. One was dot pattern, dense hypofluorescences which were detected evidently in the late phases, and some of them could be confirmed in the early phases. They clustered in the peripapillary area and dispersed sporadically to the midperiphery. The other was circular pattern, relatively lighter hypofluorescences which were evidently observed in the late phases also. They were crowded and fused in the peripapillary area or in the posterior pole and scattered to the midperiphery in a radiating pattern. These area included clinically observed white dot lesions, but were more widespread distinctively. At the recovery stages, all these hypofluorescent lesions disappeared completely. It is supposed that the former represents blocked fluorescence by inflammatory precipitates and the latter reveals circulatory disturbance in the choriocapillary or pre-capillary arteriole. Previous fluorescein angiographic and electrophysiologic studies have demonstrated the involvement of the retinal pigment epithelium(RPE) and photoreceptors in MEWDS. Our findings on ICGA suggest that the ischemic choroidal circulatory disturbance due to the inflammatory precipitates in the choroid may be the primary change and the RPE and photoreceptors may be involved secondarily.
