Choroidal thickness in retinitis pigmentosa using EDI OCT

Acta Ophthalmologica, 2013
AbstractPurpose To describe the choroidal thickness of patients with RP using enhanced depth imaging (EDI) and spectral domain (SD) optical coherence tomography (OCT), comparing with impaired non affected subjects.Methods Prospective, case‐control study of 20 patients with RP imaged using the Spectralis EDI protocol.

Automated Segmentation of the Choroid in EDI-OCT Images with Retinal Pathology Using Convolution Neural Networks [PDF]

Lecture Notes in Computer Science, 2017
The choroid plays a critical role in maintaining the portions of the eye responsible for vision. Specific alterations in the choroid have been associated with several disease states, including age-related macular degeneration (AMD), central serous choroiretinopathy, retinitis pigmentosa and diabetes.

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

Choroidal Vascularity Index in Vogt-Koyanagi-Harada Disease: An EDI-OCT Derived Tool for Monitoring Disease Progression

Translational Vision Science and Technology, 2016
We assessed the application of the choroidal vascularity index (CVI) in the follow-up of Vogt-Koyanagi-Harada disease (VKH) patients derived from image binarization of enhanced depth imaging optical coherence tomography (EDI-OCT) images with Fiji software.

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

Optometry and Vision Science, 2013
ABSTRACT 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

EDI-OCT as an auxiliary examination for the differential diagnosis of bullous CSC and Vogt-Koyanagi-Harada: A case report

Photodiagnosis and Photodynamic Therapy
A 46-year-old male patient visited our clinic with a complaint of blurred vision in the right eye accompanied by headache and insomnia. The fundus examination showed three bullous retinal detachments in the right eye. Considering the prodromal symptoms and other fundus characteristics such as vitreous cells in the posterior pole and multifocal ...

Evaluation of Subfoveal Choroidal Thickness in Children with Type 1 Diabetes Mellitus: An EDI-OCT Study

Seminars in Ophthalmology, 2013
To evaluate the subfoveal choroidal thickness (SFCT) measured by enhanced depth imaging optical coherence tomography (EDI-OCT) in children with type 1 diabetes without diabetic retinopathy.In this prospective and comparative study, 41 diabetic children without diabetic retinopathy and 42 age-matched healthy subjects were enrolled. The SFCT was measured

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
