Choroidal thickness changes determined by EDI-OCT on acute anterior uveitis in patients with HLA-B27-positive ankylosing spondylitis

International Ophthalmology, 2017
To evaluate the choroidal thickness on acute anterior uveitis in patients with HLA-B27-positive ankylosing spondylitis.In this study, 32 eyes of 16 HLA-B27 positive AS patients with anterior uveitis and age-matched 19 eyes for control group were analyzed between January 2014 and April 2015.

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.

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

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

Experimental 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.

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
