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.

Enhanced depth imaging OCT (EDI-OCT) findings in acute phase of sympathetic ophthalmia
International Ophthalmology, 2015The 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

3-D Choroidal Thickness Maps from EDI-OCT in Highly Myopic Eyes
Optometry and Vision Science, 2013Myopic 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 ...

A Texture-Based Method for Choroid Segmentation in Retinal EDI-OCT Images
International Conference/Workshop on Computer Aided Systems Theory, 2015Retinal 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

Choroidal thickness in retinitis pigmentosa using EDI OCT
Acta Ophthalmologica, 2013AbstractPurpose 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.

A Two Stage Contour Evolution Approach for the Measurement of Choroid Thickness in EDI-OCT Images
National Conference on Computer Vision, Pattern Recognition, Image Processing, and Graphics, 2017High 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.

Retinal and Choroidal Findings in Oxalate Retinopathy Using EDI-OCT
Ophthalmic Surgery, Lasers and Imaging Retina, 2012A 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 ...
