Rotor syndrome is a rare, benign familial disorder characterized by chronic fluctuating, nonhemolytic and predominantly conjugated hyperbilirubinemia with normal hepatic histology. In contrast to Dubin-Johnson syndrome, there is no liver pigmentation in Rotor syndrome. A 36-year-old man was admitted due to asymptomatic persistent jaundice. His siblings had jaundice with direct hyperbilirubinemia. Physical examination revealed icteric sclerae without hepatosplenomegaly. Laboratory findings showed increased serum bilirubin with direct bilirubinmia. Hepatic uptake and storage capacity of indocyanine green was markedly reduced, while excretion into bile was slightly suppressed. Markedly decreased hepatic uptake and poor visualization of the gallbladder and biliary tract were shown in 99mTc-DISIDA scan. Histology of the liver showed mild steatosis without pigmentation. We report a case with the review of literature.

The classification, size and activity of choroidal neovascularization (CNV) by optical coherence tomography (OCT) were compared with those obtained by fluorescein angiography (FA) and Indocyanine green angiography (ICG). This study included 32 patients (32 eyes) diagnosed as having CNV. The etiology of CNV was found to be age-related macular degeneration (AMD) or non-AMD. Patients were studied retrospectively by FA, ICG, and OCT. Of the 13 eyes with AMD, the boundary of the lesion could not be defined using FA in 7 patients. Among the 7 poorly defined CNV cases by FA, the identification of the boundary was possible in one case by OCT. The mean diameter of the classic well-defined lesions was 3500 +/- 421 micrometer by FA, 2624 +/- 1044 micrometer by ICG, and 1927 +/- 1272 micrometer by OCT. The size of the CNV by OCT was always smaller than by FA or ICG. Of the 19 eyes with Non-AMD, the boundary of the lesion could not be defined by FA in 5 patients. Among the 5 poorly defined cases by FA, the identification of the boundary was possible in 3 cases by OCT. The mean diameter of the well-defined CNV lesions was 2153 +/- 759 micrometer by FA, 1929 +/- 673 micrometer by ICG, and 1322 +/- 566 micrometer by OCT. Retinal thickness, which represents retinal edema, was found to be proportional to lesion size, although the relationship was not statistically significant. Regardless of CNV type, FA, ICG and OCT used in combination increase the specificity of diagnosis if their findings are compared.

PURPOSE: To investigate morphologic changes of acute central serous chorioretinopathy (CSC) using spectral domain optical coherence tomography (SD-OCT) and confocal scanning laser ophthalmoscopy. METHODS: This retrospective study included 63 eyes of 63 patients with unilateral acute CSC. All patients underwent simultaneous SD-OCT and fluorescein angiography examination using Spectralis HRA+OCT. RESULTS: The external limiting membrane could be seen on SD-OCT, although the junction between photoreceptor inner and outer segments (IS/OS) was not detected in all eyes with retinal detachment (RD). However, IS/OS became visible after resolution of serous RD in 51 eyes (81.0%). SD-OCT images at the leakage sites showed a bump of retinal pigment epithelium (RPE) in in 47 cases (68.1%) and pigment epithelial detachment (PED) in 22 of 69 leakage sites (31.9%). In 14 of 69 leakage sites (20.3%), highly reflective areas suggesting fibrinous exudate were observed in the subretinal space. In nine leakage sites (13.0%), sagging or dipping of the posterior retinal layer was seen. Abnormal RPE changes such as RPE bump and PED were observed in 12 of 22 fellow eyes (54.5%). CONCLUSIONS: A variety of morphologic changes could be identified on SD-OCT, and those findings may contribute more information to our understanding of the pathophysiology of CSC.

OBJECTIVE: Indocyanine green with near-infrared fluorescence imaging (NIR-ICG) is a new tracer modality in the limelight used for lymphatic mapping. The advantage of this method is to provide real-time image during surgery. To use ICG for image guided lymph node dissection, a surgeon needs to know initial appearing time and duration. METHODS: A 52-year-old woman undertook surgery diagnosed with endometrial cancer. She had no past medical history and her body mass index was 25.3 kg/m2. Preoperative magnetic resonance imaging examination revealed 2.7 cm sized cancerous mass in the endometrial cavity with superficial myometrial invasion without lymph node enlargement. Four mL (1.25 mg/mL) of ICG solution was prepared for injection. For each site, 1 mL of solution was injected superficially, 2-3 mm into the cervical submucosa and another 1 mL was injected deep, 1-2 cm into the stroma of the cervix. We recorded video with 30° 10 mm scope equipped with a specific lens and light source emitting both visible and NIR light (KARL STORZ GmbH & Co. KG, Tuttlingen, Germany). RESULTS: Pelvic lymph node was visualized from around 5 minutes. ICG was dispersed into organs after hysterectomy (53 minutes after ICG injection), yet we could clearly identify sentinel lymph node (SLN). Pathology revealed endometriod adenocarcinoma grade I, myometrial invasion with less than half of myometrium and no lymph node metastasis. CONCLUSION: Cervical injection of ICG provides good visualization of SLN from 5 minutes to over an hour. Our film gives an idea about time management to make a plan for surgery and not to miss SNLs.

To report the association of a unilateral serous macular detachment with severe postoperative pain. A 71-year-old woman presented with a sudden decrease in vision in the right eye, seven days after a total knee replacement arthroplasty. The patient's history was unremarkable except for a severe pain greater than the visual analog scale of 8 points for about 2 days after surgery. Retinal examination showed a well differentiated serous detachment that was about 3.5 disc diameter in size and located in the macular area. Fluorecein angiography and indocyanine green angiography showed delayed perfusion of the choriocapillaris without leakage points in the early phase and persistent hypofluorescence with pooling of dye in the subretinal space in the late phase. There was a spontaneous resolution of the serous detachment and the choroidal changes with residual pigment epithelial changes. Severe postoperative pain may influence the sympathetic activity and introduce an ischemic injury with a focal, choroidal vascular compromise and secondary dysfunction of overlying RPE cells in select patients.

PURPOSE: To assess the clinical outcomes in idiopathic epiretinal membrane (ERM) patients after vitrectomy and ERM removal with or without additional indocyanine green (ICG)-assisted internal limiting membrane (ILM) peeling. METHODS: The medical records of 43 patients with an idiopathic ERM that underwent vitrectomy and ERM removal between July 2007 and April 2010 were reviewed. The patients were divided into two groups: triamcinolone-assisted simple ERM peeling only (group A, n = 23) and triamcinolone-assisted ERM peeling followed by ICG staining and peeling of the remaining internal ILM (group B, n = 20). RESULTS: No difference was found between the two groups in terms of visual acuity, macular thickness, P1 amplitude or implicit time on multifocal-electroretinogram (mfERG) at six and 12 months postoperatively. In group B, ICG staining after ERM peeling demonstrated that the ILM had been removed together with the ERM in 12 eyes (60%), and all 12 eyes showed punctate retinal hemorrhages during ERM peeling. There was no recurrence of an ERM in either group. CONCLUSIONS: Additional procedures involving ICG staining and ILM peeling during ERM surgery do not appear to have an additive effect on the clinical outcomes in terms of visual acuity, retinal function based on mfERG, or recurrence rate.

7.Indocyanine Green Angiographic Findings of Obscure Choroidal Abnormalities in Neurofibromatosis.
Yong Soo BYUN ; Young Hoon PARK
Korean Journal of Ophthalmology 2012;26(3):230-234
We report two cases of choroidal neurofibromatosis, detected with the aid of indocyanine green angiography (ICGA) in patients with neurofibromatosis (NF)-1, otherwise having obscure findings based on ophthalmoscopy and fluoresceine angiography (FA). In case 1, the ophthalmoscopic exam showed diffuse bright or yellowish patched areas with irregular and blunt borders at the posterior pole. The FA showed multiple hyperfluorescent areas at the posterior pole in the early phase, which then showed more hyperfluorescence without leakage or extent in the late phase. The ICGA showed diffuse hypofluorescent areas in both the early and late phases, and the deep choroidal vessels were also visible. In case 2, the fundus showed no abnormal findings, and the FA showed weakly hypofluorescent areas with indefinite borders in both eyes. With the ICGA, these areas were more hypofluorescent and had clear borders. Choroidal involvement in NF-1 seems to occur more than expected. In selected cases, ICGA is a useful tool to be utilized when an ocular examination is conducted in a patient that has no definite findings based on the ophthalmoscope, B-scan, or FA tests.

8.Clinical Characteristics of Polypoidal Choroidal Vasculopathy Associated with Chronic Central Serous Chorioretionopathy.
Korean Journal of Ophthalmology 2012;26(1):15-20
PURPOSE: To investigate the clinical characteristics of polypoidal choroidal vasculopathy (PCV) associated with chronic central serous chorioretinopathy (CSC). METHODS: We retrospectively reviewed the medical records of 246 PCV patients (283 eyes) between July 2004 and August 2009 and investigated the clinical characteristics of the PCV patients who had specific fundus findings of chronic CSC. RESULTS: Among PCV patients, 13 eyes (4.6%) of 13 PCV patients (5.3%) had fundus findings of chronic CSC. All of the PCV lesions had a solitary polyp located outside the atrophic retina, predominantly in the macular area (84.6%), most showed an exudative pattern (69.2%) and there were a few that showed a hemorrhagic pattern (30.8%). All of the lesions were smaller than 1 disc diameter. Most of the PCV lesions (76.9%) were cured with less than two treatments in a short period of 6.4 +/- 1.9 months; however, visual acuity deteriorated (61.5%) or was not changed (30.8%) in most of the cases. CONCLUSIONS: The PCV associated with chronic CSC had several clinical features such as a small exudative retinal lesion with a solitary polyp and frequent involvement of the macular area. Even though there was poor visual outcome due to the atrophic change, all of the PCV lesions were easily resolved in a short period with a simple treatment course and no recurrence.

9.ICG-enhanced digital angiography and photocoagulation of choroidal neovascularization in age-related macular degeneration.
Sang Ha KIM ; Dong Eun LEE ; Young Jung PARK
Korean Journal of Ophthalmology 1995;9(1):59-65
Choroidal neovascular membranes are often poorly defined on fluorescein angiography because of fluorescein leakage or blockage of hyperfluorescence by overlying hemorrhage, lipid, turbid fluid, or pigment. Indocyanine green (ICG) is a highly protein-bound dye in the near infrared portion of the spectrum. Therefore, ICG remained in and around the neovascular membrane and enhanced the visualization of certain membranes poorly defined with fluorescein. ICG penetrated through the overlying turbid tissue, and improved the visualization of the underlying choroidal neovascular membrane. Using an infrared angiography system, the authors obtained 21 ICG-angiograms with suspected choroidal neovascularization, and compared them to fluorescein angiograms. In 5 of the 21 eyes, occult choroidal neovascularization was well delineated on the ICG angiograms. In 2 eyes, we were able to detect a well-defined choroidal neovascular membrane underlying a subretinal hemorrhage. In 12 of the 21 eyes with choroidal neovascular membrane, we performed argon-green laser photocoagulation applying the overlay technique of the ICG angiogram to red-free photo or the early fluorescein angiogram, and evaluated the effect of full coverage laser treatment.

PURPOSE: To determine the influence of clinical features and Indocyanine green (ICG) angiographic features on the visual outcome of patients with myopic sub-foveal choroidal neovascularization (CNV) who received photodynamic therapy (PDT). METHODS: Thirty-six consecutive patients (39 eyes) with myopic CNV who were followed up for more than one year after PDT were enrolled in this study. Clinical features included age, gender, refractive error, great linear dimension, and subretinal hemorrhage. ICG features included the lesion size, lacquer cracks, hypofluorescence surrounding the CNV (dark rim), peripapillary atrophy size, and visible prominent choroidal veins under the macula. Linear regression analysis was performed using the change in visual acuity (delta logMAR) as the dependent variable and the above factors as independent variables. RESULTS: At one-year follow-up after PDT, a younger age (p=0.002) and the presence of a dark rim (p=0.002) were significantly correlated with an improvement of visual acuity (decrement in logMAR) after PDT. Other factors had no significant influence on changes in visual acuity. CONCLUSIONS: Younger patients and patients with a dark rim on ICG angiography had a higher chance of visual improvement after PDT in myopic CNV.
