Vessel Density and Structural Measurements of Optical Coherence Tomography in Primary Angle Closure and Primary Angle Closure Glaucoma.
PURPOSE To evaluate the vessel density measurements of the optic nerve head (ONH), peripapillary, and macular regions on optical coherence tomography (OCT) angiography in eyes with primary angle closure (PAC) and primary angle closure glaucoma (PACG), and to compare their diagnostic abilities with the ONH rim area, peripapillary retinal nerve fiber layer (RNFL) thickness, and the macular gangli...
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 کاملAutomatic segmentation of the choroid in enhanced depth imaging optical coherence tomography images
Enhanced Depth Imaging (EDI) optical coherence tomography (OCT) provides high-definition cross-sectional images of the choroid in vivo, and hence is used in many clinical studies. However, the quantification of the choroid depends on the manual labelings of two boundaries, Bruch's membrane and the choroidal-scleral interface. This labeling process is tedious and subjective of inter-observer dif...
متن کاملEnhanced depth imaging optical coherence tomography of the choroid in central retinal vein occlusion.
PURPOSE To evaluate subfoveal choroidal thickness in patients with central retinal vein occlusion (CRVO) using enhanced depth imaging optical coherence tomography. DESIGN Retrospective observational study. METHODS We measured bilateral subfoveal choroidal thickness, averaged for 100 scans, in 36 patients (mean age, 66 ± 15 years; 26 women and 10 men) with unilateral CRVO by using the enhanc...
متن کاملMeasurement of choroid thickness in pregnant women using enhanced depth imaging optical coherence tomography.
PURPOSE To investigate choroidal thickness in healthy pregnant women during different trimesters using enhanced depth imaging optical coherence tomography (EDI-OCT). METHODS This prospective study included 90 healthy pregnant women in their first, second, or third trimester (groups 1, 2, and 3, respectively) and 30 non-pregnant healthy women (group 4). The age range for all groups was 18-40 y...
