Convolutional Neural Network for automatic segmentation of EDI OCT images

2019 10th International Conference on Computing, Communication and Networking Technologies (ICCCNT), 2019
Analysis of Enhanced Depth Imaging Optical Coherence Tomography (EDI OCT) images of the choroid helps in identification of many retinal disorders. Though, a wide variety of algorithms for segmenting the choroid in EDI OCT images of a healthy retina exist, very few addresses the case of infested eyes.

A Texture-Based Method for Choroid Segmentation in Retinal EDI-OCT Images

Lecture Notes in Computer Science, 2015
Retinal layers can be identified by ophthalmologists using OCT images, which is useful for the diagnosis of different diseases. Recent EDI-OCT technique allows to explore the choroid layer, whose segmentation has become one of the hottest topics in the field of retinal imaging. In this sense, and taking into account that the choroid layer has different

Enhanced depth imaging OCT (EDI-OCT) findings in acute phase of sympathetic ophthalmia

International Ophthalmology, 2015
The purpose of this study was to describe the EDI-OCT findings in an acute phase of sympathetic ophthalmia (SO). A 24-year-old gentleman was referred to clinic complaining of progressive blurry vision of his right eye within last 3 days. He had a history of repaired corneoscleral laceration in his left eye followed by lensectomy and anterior vitrectomy

GMM cluster based choroid segmentation in EDI OCT images

2017 International Conference on Computing Methodologies and Communication (ICCMC), 2017
The structure of Choroidal layer can reflect many diseases such as polypoidal choroidal vasculopathy and choroidal tumors; hence proper segmentation of this layer is a major task. Also the assessment of choroidal thickness from Enhanced Depth Imaging (EDI-OCT) image is an important basis for diagnosing. Mostly this is done by manual labeling which is a

Automated choroid segmentation of three-dimensional SD-OCT images by incorporating EDI-OCT images

Computer Methods and Programs in Biomedicine, 2018
The measurement of choroidal volume is more related with eye diseases than choroidal thickness, because the choroidal volume can reflect the diseases comprehensively. The purpose is to automatically segment choroid for three-dimensional (3D) spectral domain optical coherence tomography (SD-OCT) images.We present a novel choroid segmentation strategy ...

A Two Stage Contour Evolution Approach for the Measurement of Choroid Thickness in EDI-OCT Images

Communications in Computer and Information Science, 2018
High resolution images of the choroid can be obtained using Enhanced Depth Imaging Optical Coherence Tomography (EDI-OCT). The thickness of the choroid can be measured from these images and is used widely in clinical application for diagnosing various eye related diseases.

Determination of peripapillary vessel density in optic disc drusen using EDI-OCT and OCT angiography

open access: yesExperimental Eye Research, 2020
Optical coherence tomography angiography (OCTA) is a rapidly developing technique which generates angiographic images non-invasively. This study proposes a method to determine the vessel density in OCTA scans in general and especially the local peripapillary vessel density.

Choroid segmentation in non-EDI OCT images of multiple sclerosis patients

Kalpa Publications in Computing, 2023
Optical coherence tomography (OCT) is a non-invasive diagnostic technique that can image ocular structures. Recently, this imaging technique has been used to diagnose and monitor patients with multiple sclerosis (MS), as several clinical studies have linked the development of MS to various changes in the eye.

Retinal and Choroidal Findings in Oxalate Retinopathy Using EDI-OCT

Ophthalmic Surgery, Lasers and Imaging Retina, 2012
A 55-year-old woman with extensive retinal crystalline deposition secondary to primary hyperoxaluria presented with bilateral loss of vision secondary to oxalate retinopathy. Enhanced depth imaging optical coherence tomography revealed intraretinal, subretinal, and intraretinal and subretinal pigment epithelium, and choroidal focal hyperreflective ...
