Validity of Automated Choroidal Segmentation in SS-OCT and SD-OCT

Validity of Automated Choroidal Segmentation in SS-OCT and SD-OCT.

PURPOSE To evaluate the validity of a novel fully automated three-dimensional (3D) method capable of segmenting the choroid from two different optical coherence tomography scanners: swept-source OCT (SS-OCT) and spectral-domain OCT (SD-OCT). METHODS One hundred eight subjects were imaged using SS-OCT and SD-OCT. A 3D method was used to segment the choroid and quantify the choroidal thickness ...

Automated drusen segmentation and quantification in SD-OCT images

Spectral domain optical coherence tomography (SD-OCT) is a useful tool for the visualization of drusen, a retinal abnormality seen in patients with age-related macular degeneration (AMD); however, objective assessment of drusen is thwarted by the lack of a method to robustly quantify these lesions on serial OCT images. Here, we describe an automatic drusen segmentation method for SD-OCT retinal...

Evaluation of Normal Choroidal Thickness in Rasht Using SD-OCT EDI Imaging

Purpose: To measure choroidal thickness in normal subjects, using optical coherent tomography (OCT) in Rasht. Methods: Normal subjects older than 20 years, living in Rasht, were selected through systematic random sampling by using the city telephone directory. The subjects underwent comprehensive eye examinations for inclusion in the study. Then, choroidal thickness was measured in both eyes by...

Choroidal thickness measurement in highly myopic eyes using SD-OCT.

BACKGROUND AND OBJECTIVE To measure macular choroidal thickness (CT) using spectral-domain optical coherence tomography (OCT) and to investigate the correlation between CT and age, degree of myopia, and history of macular choroidal neovascularization (CNV). PATIENTS AND METHODS A cross-sectional study included 187 highly myopic eyes of 187 patients examined between January and December 2010. ...
