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...

PURPOSE Because of the potential usefulness of evaluating and treating choroidal neovascularization obscured by blood, we designed this study to quantify the transmission of dye fluorescence and laser energy through blood. METHODS Blood preparations anticoagulated with ethylenediaminetetraacetic acid with hematocrits of 0% (plasma), 46%, and 99% were placed in open cuvettes with path lengths ...

AIMS To evaluate angiographic features of myopic crescents using fluorescein angiography (FA) and indocyanine green angiography (IA). METHODS FA and IA angiograms of 88 highly myopic eyes (47 consecutive patients) were reviewed. The follow up period ranged from 5-28 years. RESULTS FA revealed two zones of the myopic crescent: a consistently hypofluorescent inner zone and an outer zone with ...

Abstract INTRODUCTION Anastomosis dehiscence is one of the most serious complications in colorectal surgery, influenced by many factors, especially anastomotic ischemia. Intraoperative Indocyanine Green (ICG) Fluorescence Angiography allows to assess vascular perfusion ends and anastomosis thus seeking decrease number sutures failure. MATERIAL AND METHODS A retrospective descriptive study patie...

Background/Introduction In Surgical revascularization by CABG surgery Left internal mammary artery (LIMA) to Lt.ant.descending (LAD) is considered gold standard conduit of choice for myocardial revascularization. Although conventional angiography is gold standard for assessing graft patency but rarely available in operating room in Bangladesh. So intraoperative florescence imaging (Novadaq Tech...

PURPOSE To report a case with anterior and posterior nodules associated with systemic sarcoidosis. METHODS A patient with decreased vision underwent complete ophthalmologic examination, ultrasound biomicroscopy, fluorescein and indocyanine green (ICG) angiography. RESULTS The patient presented a nodule of the iris of the OS and of the optic nerves of both eyes. Chest computed tomography and...

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 ...

Normal retinal tissue consists of the nine-layer sensory retina on the vitreous side and onelayer retinal pigment epithelium on the choroidal side. Serous retinal detachment is a detachment of the sensory retina from the retinal pigment epithelium. Central serous chorioretinopathy (CSC) is a condition causing local serous neurosensory detachment in the macular region. CSC causes circular or ova...
