PURPOSE: To determine interobserver and intraobserver agreement in classifying the subtypes of choroidal neovascularization (CNV) and the decision of retreatment in patients affected by exudative age-related macular degeneration. Different imaging techniques were evaluated individually and compared with multiimaging. METHODS: Fifty-two patients with naive CNV in age-related macular degeneration were evaluated after 3 monthly intravitreal injections of ranibizumab...

PURPOSE: To compare the diagnostic ability of optical coherence tomography angiography (OCTA) with indocyanine green angiography (ICGA) in polypoidal choroidal vasculopathy (PCV). METHODS: Retrospective review of 47 eyes with PCV imaged with ICGA and OCTA. For each eye, it was determined which imaging modality better delineated the PCV complex. The presence of a branching vascular network (BVN) and polyp(s) were noted. RESULTS: PCV was better visualized with ICGA in 21 eyes (44...

Purpose: To determine whether combination photodynamic therapy (PDT) and antivascular endothelial growth factor (VEGF) therapy is effective in the management of chronic central serous chorioretinopathy (CSC) recalcitrant to conventional therapy. Methods: This was a retrospective analysis of eight patients with chronic CSC unresponsive to topical nonsteroidal anti-inflammatory drugs, focal photocoagulation, anti-VEGF alone, or PDT alone. All patients were evaluated with a full ophthalmic examination, spectral-domain optical coherence tomography (OCT), fluorescein angiography (FA), and most with indocyanine green angiography (ICGA) followed by treatment with half-fluence PDT and intravitreal anti-VEGF injection (seven bevacizumab, one aflibercept)...

PURPOSE: To study presenting characteristics and prevalence of polypoidal choroidal vasculopathy (PCV) in Scandinavian Caucasians with treatment-naïve exudative age-related macular degeneration (AMD). METHODS: We reviewed all patients referred in year 2014 and diagnosed using fundus examination, optical coherence tomography, and fluorescein and indocyanine green angiography (ICGA). Details of found PCVs and its subtypes (clinical and angiographical) were correlated to the baseline best-corrected visual acuity (BCVA)...

The aim of the present study is to assess the effects of unilateral revascularization on the contralateral foot circulation using indocyanine green (ICG). From January 2016 to April 2016, a total of twenty-one patients were included in this study. The patients underwent elective unilateral revascularization at our institution and we evaluated the feet circulation by indocyanine green angiography (ICGA) tests preoperatively and postoperatively. The ICGA parameters included the magnitude of intensity from the onset of ICG to the maximum intensity (Imax), the time from the onset of ICG to the maximum intensity (Tmax), and the time required to reach the half maximum intensity from the onset of ICG (T1/2)...

BACKGROUND: Although photodynamic therapy (PDT) has become the standard treatment for central serous chorioretinopathy (CSC), its mechanism of action remains unclear. It is assumed that PDT induces short-term choriocapillaris (CC) occlusion and long-term choroidal vascular remodeling. In this paper, we describe the short-term CC changes induced by Half-Dose PDT (HD-PDT) in chronic CSC using optical coherence tomography-angiography (OCTA). METHODS: This is a prospective interventional case series...

Purpose: To investigate the hemodynamics of the choriocapillaris in primate eyes under elevated intraocular pressure. Methods: Indocyanine green angiography (ICGA) and fluorescein angiography (FA) were performed in two monkeys after elevation of the intraocular pressure (IOP) to 35 and 60 mm Hg. Results: ICGA and FA showed no perfusion delays in the choriocapillaris at 35 mm Hg. The slow dye filling at 60 mm Hg made it possible to observe the early phase angiography sequence...

PURPOSE: Complications in wound healing after neurosurgical operations occur often due to scarred dehiscence with skin blood perfusion disturbance. The standard imaging method for intraoperative skin perfusion assessment is the invasive indocyanine green video angiography (ICGA). The noninvasive dynamic infrared thermography (DIRT) is a promising alternative modality that was evaluated by comparison with ICGA. METHODS: The study was carried out in two parts: (1) investigation of technical conditions for intraoperative use of DIRT for its comparison with ICGA, and (2) visual and quantitative comparison of both modalities in a proof of concept on nine patients...

Purpose: To use a novel optical coherence tomography angiography (OCTA) algorithm termed variable interscan time analysis (VISTA) to evaluate relative blood flow speeds in polypoidal choroidal vasculopathy (PCV). Methods: Prospective cross-sectional study enrolling patients with confirmed diagnosis of PCV. OCTA of the retina and choroid was obtained with a prototype swept-source OCT system. The acquired OCT volumes were centered on the branching vascular network (BVN) and polyps as determined by indocyanine-green angiography (ICGA)...

Rotational vertebral artery occlusion (RVAO) is a well-documented surgically amenable cause of vertebrobasilar insufficiency. Traditionally, patients have been imaged using dynamic rotational angiography. We report a case of RVAO in which intraoperative indocyanine green angiography (ICGA) was used to confirm adequate surgical decompression of the VA. A 57-year-old female who presented with multiple episodes of syncope provoked by turning her head to the right. Rotational dynamic angiography revealed a dominant right VA that became occluded at the level of C5/6 with head rotation to the right...

PURPOSE: To evaluate indocyanine green angiography (ICGA) for the identification and characterization of afferent (feeding) and efferent (draining) vessels in patients with ocular surface neoplasia. MATERIALS AND METHODS: Consecutive patients with biopsy-proven benign, pre-invasive, or invasive ocular surface tumors of the bulbar conjunctiva were included. Patients underwent anterior segment optical coherence tomography, ICGA, and color photography for the evaluation of the thickness, location, number, and diameter of afferent and efferent vessels of the lesions...

Purpose: To assess the occurrence of choroidal neovascularization (CNV) secondary to chronic central serous chorioretinopathy (CSCR) using optical coherence tomography angiography (OCTA) and correlate these findings with choroidal thickness (CT). Materials and Methods: This retrospective study included 25 consecutive patients (43 eyes), mean age 48.12 ± 7.8 years, diagnosed with persistent CSCR. All patients underwent a complete ophthalmic examination, fluorescein angiography (FA), indocyanine green angiography (ICGA), optical coherence tomography, and OCTA...

PURPOSE: To detect, using multimodal imaging, lacquer cracks (LCs) and myopic stretch lines (MSLs) in pathologic myopic eyes with macular hemorrhage (MHE) and those without. METHODS: We collected 18 consecutive pathologic myopic eyes (spherical equivalent ≤ -8.0 diopters) that had presented with linear, yellowish-white lesions in the macula. We categorized the eyes into either the MHE group or the non-MHE group. All underwent fluorescein angiography (FA), near infrared autofluorescence (NIA), indocyanine green angiography (ICGA), and spectral-domain optical coherence tomography (SD-OCT)...

Syphilitic chorioretinitis should be included in differential diagnosis of any form of ocular inflammation. A significantly higher proportion of human immunodeficiency virus (HIV)-positive patients with ocular syphilis as compared to HIV-negative cases have been reported in published studies. However, the clinical signs and symptoms are more insidious in HIV-negative patients who are easily misdiagnosed. We report a series of cases of ocular syphilis and describe the clinical manifestations and treatment outcomes of syphilitic chorioretinitis in HIV-negative patients in China...

PURPOSE: To describe causes, visual outcomes, and prognostic factors in patients with submacular hemorrhage (SMH). DESIGN: Retrospective case review. METHODS: We performed a retrospective review of SMH with a size of at least 1 disc diameter. SMH causes were classified into 3 groups: 1) neovascular age-related macular degeneration (nAMD), 2) polypoidal choroidal vasculopathy (PCV), and 3) other miscellaneous causes.
