Seeing decreased hyperreflective foci in enhanced-depth OCT images of the patients with chronic VKH, Fong et al. speculated that stromal scarring and the resulting shrinkage and dropout of small vessels in the choroid are the reasons for choroidal thinning in the convalescent stage of VKH [14].
To investigate a potential circadian fluctuation of the choroidal volume in healthy adults by enhanced depth imaging (EDI) via spectral-domain optical coherence tomography (SD OCT).
The subfoveal choroidal thickness was manually measured by the caliper function in the enhanced depth imaging OCT (EDI-OCT) images.
To date, there has not been a study of choroidal structure in eyes with Wyburn-Mason syndrome by enhanced depth imaging OCT (EDI-OCT).
Standardized, masked manual measurement of the choroidal thickness was performed in the center of the ETDRS fields on enhanced depth imaging (EDI) scans.
With enhanced depth imaging, the posterior vitreous surface is not visualized, whereas in the combined depth imaging, both the posterior vitreous surface and the outer choroid are visualized.
In this paper, we suggest the rotating counsel refinement (RCR), the filtering, is used to remove the tiny jagged edge of enhanced depth maps.
After depth enhancement, the enhanced depth maps by the proposed AMF process as well as JBF and AJRF methods with CHF are shown in Fig. 7.
To measure choroidal thickness (CT) in myopic eyes using enhanced depth imaging (EDI).
To demonstrate the 3-dimensional choroidal volume distribution in healthy subjects using enhanced depth imaging (EDI) spectral-domain optical coherence tomography (SD-OCT) and to evaluate its association with age, sex, and axial length.
In Fig. 10a, the enhanced depth map of the proposed method has smaller depth values in the left half of histogram, representing less visual fatigue; in Fig. 10b, the enhanced depth map of the proposed method focusses on the central region of the histogram which means less visual fatigue.
