EDI-OCT choroidal thickness in Posner–Schlossman syndrome

International Ophthalmology, 2020
To compare the choroidal thickness (CT) of the affected eyes with the contralateral eyes in the active period and in the remission period in Posner-Schlossman syndrome (PSS) using EDI-OCT.This prospective longitudinal study included 15 patients with PSS and 15 age- and sex-matched healthy subjects.

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.

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.

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

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.

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 ...

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 ...
