Choroid segmentation in non-EDI OCT images of multiple sclerosis patients
Kalpa Publications in Computing, 2023Optical 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.

Convolutional Neural Network for automatic segmentation of EDI OCT images
2019 10th International Conference on Computing, Communication and Networking Technologies (ICCCNT), 2019Analysis 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.

Enhanced depth imaging OCT (EDI-OCT) findings in acute phase of sympathetic ophthalmia
International Ophthalmology, 2015The 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

A Two Stage Contour Evolution Approach for the Measurement of Choroid Thickness in EDI-OCT Images
Communications in Computer and Information Science, 2018High 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.

Automated choroid segmentation of three-dimensional SD-OCT images by incorporating EDI-OCT images
Computer Methods and Programs in Biomedicine, 2018The 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 ...

Choroid Characterization in EDI OCT Retinal Images Based on Texture Analysis
Proceedings of the International Conference on Agents and Artificial Intelligence, 2015Optical Coherence Tomography (OCT) is a widely extended imaging technique in the opthalmic field for diagnostic purposes. Since layers composing retina can be identified in these images, several image processingbased methods have been presented to segment them automatically in these images, with the aim of developing medical-support ...

3‐D Choroidal Thickness Maps from EDI‐OCT in Highly Myopic Eyes
Optometry and Vision Science, 2013ABSTRACT Purpose Myopic chorioretinal atrophy is a debilitating condition that causes severe loss of primary vision. However, its mechanisms and pathologic course are not well understood. We performed volumetric measurements of the posterior choroid via three‐dimensional analysis of the choroid

Determination of peripapillary vessel density in optic disc drusen using EDI-OCT and OCT angiography
Experimental Eye Research, 2020Optical 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.
