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 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

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.

EDI-OCT evaluation of choroidal thickness in retinitis pigmentosa

European Journal of Ophthalmology, 2017
Purpose: To evaluate choroidal thickness (CT) in retinitis pigmentosa (RP) using enhanced depth imaging (EDI) optical coherence tomography (OCT). Methods: A retrospective analysis of a group of patients with RP who underwent EDI-OCT was performed. Choroidal thickness measurements were compared with those of age- and sex-matched healthy subjects. In the

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 ...

3-D Choroidal Thickness Maps from EDI-OCT in Highly Myopic Eyes

Optometry and Vision Science, 2013
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 in patients with high myopia to understand its structure, and we compared ...

Choroid Characterization in EDI OCT Retinal Images Based on Texture Analysis

Proceedings of the International Conference on Agents and Artificial Intelligence, 2015
Optical 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 ...

Sensitivity and specificity of choroidal thickness measurement by EDI-OCT for central serous chorioretinopathy diagnosis

International Ophthalmology, 2020
To evaluate the utility of choroidal thickness (CT) measurement by enhanced depth imaging optical coherence tomography (EDI-OCT) for central serous chorioretinopathy (CSC) diagnosis.Cross-sectional comparative study of 62 consecutive patients: 38 with acute CSC and 24 with macular subretinal fluid from differential diagnoses (DD). Subfoveolar choroidal
