This comparative study between a SD- and SS-OCTA system for visualizing neovascular patterns in AMD, also assessed the influence of cataract on OCTA imaging. 25 eyes with active CNV (AMD) were documented by FA, ICGA and SD-OCT. Two OCTA devices were used: A custom built SS-OCTA (1050 nm, 400,000 A-scans/s, 5 × 5 mm, no image segmentation); AngioVue (OptoVue, CA, USA) SD-OCTA (840 nm, 70.000 A-scans/s, 3 × 3 mm, SSADA technology). Two retina experts graded CNV types and vascular patterns. Cataract influence on OCTA image quality was reported for the superficial retinal plexus (6 eyes)...

PURPOSE: To compare the findings of optical coherence tomography angiography (OCTA) with indocyanine green angiography (ICGA) in polypoidal choroidal vasculopathy (PCV) that was divided into two types: polypoidal choroidal neovascularisation (CNV) and typical PCV (type 2 PCV). METHODS: We studied a retrospective case series of 32 patients with treatment-naïve PCV (24 men, eight women; mean age 65.4 years). PCV was categorised into polypoidal CNV (type 1 PCV) and type 2 PCV based on ICGA findings...

PURPOSE: Grading of disease activity in patients with atopic keratoconjunctivitis (AKC) is limited by intra- and inter-observer variability. The aim of this study was to identify angiographic parameters to help evaluate inflammation and disease activity. METHODS: In 12 patients (4 with active, 2 with inactive AKC, and 6 controls), disease activity were assessed using a validated biomicroscopic grading scale. Imaging of upper tarsal conjunctiva was undertaken using color photography, fluorescein (FA) and indocyanine green angiography (ICGA)...

PURPOSE: In geographic atrophy (GA), choroidal vessels typically appear on structural optical coherence tomography (OCT) as hyperreflective round areas with highly reflective borders. We observed that some GA eyes show choroidal round hyporeflectivities with highly reflective borders beneath the atrophy, and futher investigated the charcteristcs by comparing structural OCT, indocyanine green angiography (ICGA) and OCT angiography (OCT-A). METHODS: Round hyporeflectivities were individuated from a pool of patients with GA secondary to non-neovascular age-related macular degeneration consecutively presenting between October 2015 and March 2016 at the Medical Retina & Imaging Unit of the University Vita-Salute San Raffaele...

PURPOSE: Vogt-Koyanagi-Harada (VKH) disease is a primary autoimmune stromal choroiditis. Aim of the study was to gather a body of evidence from the literature and from experts that systemic corticosteroid combined with non-steroidal immunosuppressive therapy should become the standard of care in initial-onset VKH disease. METHODS: Literature was reviewed and leading experts in VKH were consulted in different parts of the world in order to put forward a consensus attitude in the management of initial-onset VKH disease...

PurposeTo compare optical coherence tomographic angiography (OCTA) and indocyanine green angiography (ICGA) images for detecting polypoidal lesions (PLs) and branching vascular networks (BVNs), and to measure the polypoidal areas (PAs) in patients with polypoidal choroidal vasculopathy (PCV).MethodsAll patients underwent ICGA, optical coherence tomography (OCT), and OCTA. We compared the detection sensitivity for PL and BVN, as evaluated by the ICGA and OCTA images. Furthermore, PA measured by ICGA was divided into two groups: one in which the area could be measured by OCTA (ICGA(+)OCTA(+)) and the other in which the area could not be measured by OCTA (ICGA(+)OCTA(-))...

BACKGROUND: Polypoidal choroidal vasculopathy (PCV) is characterized by the presence of polyps with or without a branching vascular network and more prevalent among Asians. The aim of this study was to compare the outcomes of conbercept therapy between two different angiographic subtypes of PCV. METHODS: Fifty-eight patients of PCV were classified into two phenotypes according to indocyanine green angiography (ICGA). In Type 1, both feeder and draining vessels are visible on ICGA and network vessels are numerous...

OBJECTIVE: The purpose of this study was to evaluate which primary wound closure technique for ankle fractures affords the most robust perfusion as measured by laser-assisted indocyanine green angiography (LA-ICGA): Allgöwer-Donati or vertical mattress. DESIGN: Prospective, randomized. SETTING: Level 1 Academic Trauma Center. PATIENTS/PARTICIPANTS: Thirty patients undergoing open reduction internal fixation (ORIF) for ankle fractures were prospectively randomized to Allgöwer-Donati (n=15) or vertical mattress (n=15) closure...

OBJECTIVES: Microsurgical subinguinal varicocelectomy is one of the best treatment modalities for varicoceles related to male infertility and scrotal pain. However, the difficulty in identifying testicular arteries, which should be spared, is a limitation of this technique. To visualize and identify the testicular arteries in spermatic cord during the operation, we examined the efficacy of intraoperative indocyanine green angiography (ICGA), which is regularly used in microsurgical neurosurgery...

PURPOSE: The purpose of the study was to evaluate the 1-year visual and anatomical outcomes of combination therapy with intravitreal aflibercept (IVA) and verteporfin photodynamic therapy (vPDT) for polypoidal choroidal vasculopathy (PCV), and to determine the predictors of a good visual outcome. METHODS: This was a prospective case-series study. Twenty eyes from 20 treatment-naïve PCV patients were treated with combination therapy with IVA and vPDT. Best-corrected visual acuity (BCVA) and morphological parameters including polypoidal lesions in indocyanine green angiography (ICGA) were evaluated over 12 months of follow-up...

PURPOSE: Retinochoroidal anastamosis (RCA) is known to be associated with retinal angiomatous proliferans rather than idiopathic macular telangiectasia. The case report describes a rare association of bilateral RCA with type II idiopathic macular telangiectasia in an elderly woman. CASE REPORT: A 65-year-old female patient presented with decreased vision in both eyes to the ophthalmology clinic. She was diagnosed with bilateral large serous retinal pigment epithelial detachments (PED)...

Fluorescein angiography (FA) and indocyanine green angiography (ICGA) have been the gold standard for the evaluation of retinal and choroidal vasculature in the last three decades and have revolutionized the diagnosis of retinal and choroidal vascular diseases. The advantage of these imaging modalities lies in their ability to document retinal and choroidal vasculature through the dynamic assessment of contrast transit over time in the intravascular and extravascular spaces. However, disadvantages include the absence of depth resolution, blurring of details by contrast leakage, and the inability to selectively evaluate different levels of the retinal and choroidal microvasculature...

PURPOSE: To investigate fixed-dosing aflibercept for treating polypoidal choroidal vasculopathy (PCV). METHODS: This phase IV, prospective, single-arm, interventional case series was conducted in eight centers. Forty treatment-naïve PCV patients were administered three monthly doses of intravitreal aflibercept (2.0 mg) and an injection every 2 months thereafter. Best-corrected visual acuity (BCVA) and central subfield macular thickness (CSMT) were measured at each visit...

BACKGROUND/AIMS: To compare the short-term efficacy of intravitreal aflibercept treatment according to the subtypes of polypoidal choroidal vasculopathy (PCV) based on indocyanine green angiography (ICGA). METHODS: Twenty-nine patients (29 eyes) with treatment-naïve subfoveal PCV were consecutively enrolled in this institutional study. The subjects were classified into two subtypes (type 1, polypoidal choroidal neovascularisation (CNV), 16 eyes; and type 2, idiopathic PCV, 13 eyes) based on the presence or absence of both feeder and draining vessels on ICGA...

PURPOSE: To describe and interpret the features of pachychoroid neovasculopathy (PNV) using optical coherence tomography angiography (OCTA) technique. METHODS: This is an observational case series of patients who presented with PNV.

Skin flap vascularity is a critical determinant of aesthetic results in autologous ear reconstruction. In this study, we investigate the use of intraoperative laser-assisted indocyanine green angiography (ICGA) as an adjunctive measure of skin flap vascularity in pediatric autologous ear reconstruction. Twenty-one consecutive pediatric patients undergoing first-stage autologous total ear reconstruction were retrospectively evaluated. The first 10 patients were treated traditionally (non-ICGA), and the latter 11 patients were evaluated with ICGA intraoperatively after implantation of the cartilage construct and administration of suction...
