DIAGNOSTIC CHARACTERISTICS OF POLYPOIDAL CHOROIDAL VASCULOPATHY BASED ON B-SCAN SWEPT-SOURCE OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY AND ITS INTERRATER AGREEMENT COMPARED WITH INDOCYANINE GREEN ANGIOGRAPHY
Purpose: To examine the characteristics of polypoidal choroidal vasculopathy using B-scan optical coherence tomography angiography (OCTA), and determine the diagnostic criteria of polypoidal choroidal vasculopathy based on OCTA. Methods: This retrospective case series included patients diagnosed with treatment-nave polypoidal choroidal vasculopathy who underwent indocyanine green angiography (ICGA) and swept-source OCTA at baseline. We compared the characteristics of the polyps detected using B-scan OCTA and ICGA. Then, the diagnostic concordance of ...Read Full ArticleMentions: Nagoya University -

High-spatial-resolution deep tissue imaging with spectral-domain optical coherence microscopy in the 1700-nm spectral band
We present three-dimensional (3-D) high-resolution spectral-domain optical coherence microscopy (SD-OCM) by using a supercontinuum (SC) fiber laser source with 300-nm spectral bandwidth (full-width at half-maximum) in the 1700-nm spectral band. By using low-coherence interferometry with SC light and a confocal detection scheme, we realized lateral and axial resolutions of 3.4 and 3.8m in tissue ( n =1.38), respectively. This is, to the best of our knowledge, the highest ...Read Full Article -

Automated Detection of Macular Diseases by Optical Coherence Tomography and Artificial Intelligence Machine Learning of Optical Coherence Tomography Images
Purpose . Although optical coherence tomography (OCT) is essential for ophthalmologists, reading of findings requires expertise. The purpose of this study is to test deep learning with image augmentation for automated detection of chorioretinal diseases. Methods . A retina specialist diagnosed 1,200 OCT images. The diagnoses involved normal eyes ( ) and those with wet age-related macular degeneration (AMD) ( ), diabetic retinopathy (DR) ( ), epiretinal membranes (ERMs) ( ), and another 19 diseases. Among them, 1,100 ...Read Full ArticleMentions: Nagoya University -
Collateral vessels on optical coherence tomography angiography in eyes with branch retinal vein occlusion
Aims To detect collateral vessels using optical coherence tomography angiography (OCTA) in eyes with branch retinal vein occlusion (BRVO) and to investigate the associations with visual outcomes and macular oedema. Methods Eyes with macular oedema secondary to BRVO that underwent OCTA at baseline and were followed up for more than 6 months were enrolled. The presence of collaterals, whether the collaterals were leaky or not, and the associations with visual ...Read Full ArticleMentions: Nagoya University -
Changes in choriocapillaris and retinal morphology after laser photocoagulation by OCT angiography
Rationale: Earlier studies have shown that laser photocoagulation treatments are associated with good long-term visual acuity in most patients with severe nonproliferative diabetic retinopathy (S-NPDR). Histopathologic studies of autopsied eyes have demonstrated defects in the choriocapillaris beneath the retinal laser lesions secondary to photocoagulation for S-NPDR. These lesions have been observed to expand centrifugally over time especially in the posterior pole, and the atrophy of the retinal pigment epithelium (RPE ...Read Full ArticleMentions: Nagoya University -
CHARACTERISTICS AND CLASSIFICATION OF TYPE 3 NEOVASCULARIZATION WITH B-SCAN FLOW OVERLAY AND EN FACE FLOW IMAGES OF OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY
Purpose: To study B-scan flow overlay and en face flow optical coherence tomography angiography (OCT-A) images of Type 3 neovascularization (NV) and to characterize a staging system for Type 3 NV based on the OCT-A findings. Methods: We retrospectively collected data on consecutive treatment-naive eyes with Type 3 NV. All eyes underwent fluorescein angiography, indocyanine green angiography, structural spectral domain OCT, and OCT-A (AngioPlex). Localization and extension of abnormal flows ...Read Full ArticleMentions: Nagoya University -
Association of Foveal Avascular Zone Enlargement and Diabetic Retinopathy Progression Using Optical Coherence Tomography Angiography
Purpose: The purpose of this article is to evaluate long-term change of the foveal avascular zone (FAZ) area in diabetic eyes using optical coherence tomography angiography (OCTA) (AngioVue, Avanti OCT, Optovue). Methods: A retrospective chart review was conducted of patients who had undergone OCTA fundus examinations with at least 12 months of follow-up. Eyes with previous laser photocoagulation and antivascular endothelial growth factor treatments were excluded. ImageJ software was used ...Read Full Article -
Wavelength Dependence of Ultrahigh-Resolution Optical Coherence Tomography Using Supercontinuum for Biomedical Imaging
Optical coherence tomography (OCT) is a noninvasive cross-sectional imaging technique with micrometer resolution. The theoretical axial resolution is determined by the center wavelength and bandwidth of the light source, and the wider the bandwidth, the higher the axial resolution. The characteristics of OCT imaging depend on the optical wavelength used. In this paper, we investigated the wavelength dependence of ultrahigh-resolution (UHR) OCT using a supercontinuum for biomedical imaging. Wideband, high-power ...Read Full Article -

Design A retrospective, observational case series Methods Optical coherence tomography angiography (OCTA) was used to obtain 3 mm 3 mm en face images before and 2, 4, and 8 weeks after the vitrectomy with ILM peeling for 20 eyes of 20 patients with an idiopathic macular hole ...Read Full ArticleMentions: Nagoya University -
Quantification of Macular Microvascular Changes in Patients With Retinitis Pigmentosa Using Optical Coherence Tomography Angiography
Purpose : To evaluate the microvascular changes in eyes with RP quantitatively using optical coherence tomography angiography (OCTA) and to determine whether the correlations between these indices and the severity of RP are significant. Methods : This was a retrospective, observational study. The medical records of 53 RP patients and 46 controls were reviewed. The OCTA images were obtained with the Cirrus 5000 with Angioplex, and an automated program was used to ...Read Full ArticleMentions: Nagoya University -
The combination assessment of lipid pool and thrombus by optical coherence tomography can predict the filter no-reflow in primary PCI for ST elevated myocardial infarction
The usefulness of distal protection devices is still controversial. Moreover, there is no report on thrombus evaluation by using optical coherence tomography (OCT) for determining whether to use a distal protection device. The aim of the present study was to investigate the predictor of filter no-reflow (FNR) by using OCT in primary percutaneous coronary intervention (PCI) for ST-elevated acute myocardial infarction (STEMI). We performed preinterventional OCT in 25 patients with ...Read Full ArticleMentions: Nagoya University -
OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY OF THE FOVEAL AVASCULAR ZONE IN CHILDREN WITH A HISTORY OF TREATMENT-REQUIRING RETINOPATHY OF PREMATURITY

About Nagoya University
Nagoya University is a Japanese national university headquartered in Chikusa-ku, Nagoya. It is one of the former 9 imperial universities. Nagoya University began its history in 1871 with its temporary hospital standing on a site where the conference chamber for the former Nagoya clan once stood, and the temporary medical school standing on a site where the magistrate's office for the former Nagoya clan once stood. Thereafter, many transitions took place, and the Aichi Medical College was established in 1920. In 1931, the management of the Aichi Medical College was transferred to the national government and the Nagoya Medical College was newly established in the same year. In 1939, the Nagoya Imperial University was established with the addition of the School of Science and Engineering and the School of Medicine, thus absorbing the Nagoya Medical College.
