Repeatability of manual subfoveal choroidal thickness measurements in healthy subjects using the technique of enhanced depth imaging optical coherence tomography.
PURPOSE The aim of this study was to investigate the repeatability of manual measurements of choroidal thickness in healthy subjects imaged on spectral domain optical coherence tomography (OCT) using the enhanced depth imaging (EDI) technique. METHODS Fifty consecutive, healthy, young, adult volunteers with no known eye disease were enrolled prospectively. Two good-quality horizontal and vert...
متن کاملReproducibility of retinal and choroidal thickness measurements in enhanced depth imaging and high-penetration optical coherence tomography.
PURPOSE Two optical coherence tomography (OCT) modalities can visualize the choroid: high-penetration OCT (HP-OCT) using a long wavelength, and enhanced depth imaging technique using Heidelberg OCT (EDI-OCT). The purpose of this study was to compare and investigate the agreement among the retinal/choroidal thickness parameters. METHODS Twenty-four eyes of 12 healthy volunteers were examined s...
متن کاملTopographic variation and interocular symmetry of macular choroidal thickness using enhanced depth imaging optical coherence tomography.
PURPOSE To report and analyze factors influencing topographical and interocular variations in choroidal thickness (CT) in a healthy adult population. METHODS One hundred eyes of 50 healthy subjects underwent visual acuity and axial length measurements and optical coherence tomography (OCT) with enhanced depth imaging (EDI). CTs at the fovea and at 3 mm nasal, temporal, superior, and inferior ...
متن کاملEnhanced depth imaging optical coherence tomography.
Imaging the choroid with conventional commercial spectral-domain optical coherence tomography (SD-OCT) has been difficult, mainly because of difficulty in signal transmission beyond the retinal pigment epithelium. A recent modification to the standard technique, termed enhanced depth imaging optical coherence tomography (EDI-OCT), was able to image the choroid with reasonable clarity using comm...
متن کاملRepeatability and Reproducibility of Macular Thickness Measurements Using Fourier Domain Optical Coherence Tomography
AIM To evaluate repeatability and reproducibility of macular thickness measurements in visually normal eyes using the Topcon 3D OCT-1000. METHODS Phase 1 investigated scan repeatability, the effect of age and pupil dilation. Two groups (6 younger and 6 older participants) had one eye scanned 5 times pre and post- dilation by 1 operator. Phase 2 investigated between-operator, within and betwee...
