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.

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

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.

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

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 ...

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.

EDI‐OCT is less suited for close monitoring of primary stromal choroiditis when compared to Indocyanine green angiography

Acta Ophthalmologica, 2016
PurposeInvestigate the performance, utility, and precision, of enhanced depth imaging optical coherence tomography thickness (EDI‐OCT‐T), versus indocyanine green angiography (ICGA), in tracking any fluctuation in the activity of primary stromal choroiditis (PSC) in response to therapy during long‐term follow‐up.MethodsPatients with a diagnosis of PSC;
