vitreous cavity. Strong glial fibrillary acidic protein positivity confirms the diagnosis. Thickening of the vessel walls, perivascular pigment, intralesional cysts, and calcareous deposits (calcospherites) are also detectable. Massive retinal gliosis is characteristically encountered in phthisical eyes after trauma, surgery, or inflammation and in other conditions such as retinopathy of premat...
Indocyanine green fluorescence (ICG) angiography of the choroid gives better visualization of the choroidal vessels than does fluorescein angiography. We found that the detachment of the pigment epithelium seems bigger on ICG than on fluorescein angiograms, and pigmented lesions are more clearly delineated.
PURPOSE To facilitate the interpretation of the choroidal dye filling sequence, the use of simultaneous indocyanine green (ICG) and fluorescein angiography was evaluated. METHODS A single-wavelength scanning laser ophthalmoscope (SLO) was modified to a two-wavelength system, permitting the simultaneous recording of ICG and fluorescein angiography. This method has been used in 340 cases. About...
Purpose. To show the long-term results of intravitreal ranibizumab combined with photodynamic therapy (PDT) for the treatment of polypoidal choroidal vasculopathy (PCV). Methods. We analyzed the progress of two patients for 36 and 58 months, respectively. We only used PDT for the treatment in the area of the active PCV or "hot spot" evident on the indocyanine green angiography (ICGA). The spot ...
PURPOSE It is known that the amplitudes of the multifocal electroretinograms are generally reduced soon after photodynamic therapy (PDT). The purpose of this study was to determine whether this amplitude reduction correlates with the changes in macular thickness or with changes in choroidal circulation. METHODS Thirty-seven eyes that were successfully treated by PDT were studied. Focal macula...
Patients with primary cutaneous melanoma underwent sentinel node (SN) mapping and biopsy at 25 facilities in Japan by the combination of radiocolloid with gamma probe and dye. Technetium-99m ((99m)Tc)-tin colloid, (99m)Tc-phytate, 2% patent blue violet (PBV) and 0.4% indigo carmine were used as tracers. In some hospitals, 0.5% fluorescent indocyanine green, which allows visualization of the SN ...
PURPOSE To report a neovascular age-related macular degeneration pattern refractory to ranibizumab. DESIGN Retrospective, observational case series. METHODS Between March and May 2009, cases with neovascular age-related macular degeneration refractory to ranibizumab were investigated with indocyanine green angiography. We identified 12 eyes of 12 patients with polypoidal choroidal vasculopa...
OBJECTIVE To determine the natural course of well-defined plaque choroidal neovascularization (CNV) using indocyanine green angiography. METHODS Two ophthalmologists, experts in macular diseases and indocyanine green angiography, examined 40 eyes with exudative age-related macular degeneration and a well-defined plaque CNV using complete ophthalmoscopic evaluation, fluorescein angiography, an...
Objective: In this case report, we present a case wherein we observed a blocking of lymphatic vessels in indocyanine green lymphography and found a shrunken lymphatic vessel intraoperatively. Methods: We performed indocyanine green lymphography and lymphaticovenous anastomosis on a 77-year-old woman. She had previously undergone right mastectomy and axillary lymph node dissection accompanied by...
BACKGROUND Dye solutions for intraoperative staining of epiretinal membranes and the internal limiting membrane improve the visualisation of these thin structures and facilitate their removal. In the present study the authors investigated the effects of indocyanine green 0.05%, trypan blue 0.15%, and patent blue 0.48% on bovine retinal function. METHODS Bovine retina preparations were perfuse...
