Ellipsoid zone on optical coherence tomography: a review
2015年11月21日 · Optical coherence tomography (OCT) images and multifocal electroretinogram (mfERG) responses from an intermediate age-related macular degeneration eye. OCT scans show drusen regression and change in the ellipsoid zone (EZ) integrity at the 12-month visit and the recovery of the EZ integrity at the 24-month visit.
The Ellipsoid Zone and the RPE. A critical differentiation.
2016年5月2日 · Distinguishing between the ellipsoid zone and the retinal pigment epithelium (RPE) is one of the most important steps when qualitatively evaluating an OCT. The ellipsoid zone is a consensus term based on current understanding of OCT lexicon and landmarks.
Assessing Photoreceptor Structure Associated with Ellipsoid Zone ...
One of the most promising applications of en face OCT is the measurement of ellipsoid zone (EZ) disruption, to provide insight into photoreceptor structure.
2015年8月21日 · Despite the lack of consen-sus of the actual origin of the ellipsoid zone, there has been much interest in evaluating its integrity and intensity in different disease processes. This review paper aims to provide an overview of the ellipsoid zone and its …
The recent International Nomenclature for OCT Panel has proposed that this hyperreflective layer be referred to as the “ellipsoid zone” rather than what has been previously believed to be the junction between the inner and outer segments of photoreceptors.
Ellipsoid Zone Mapping Parameters in Retinal ... - Ophthalmology …
2017年7月16日 · To evaluate the association of baseline ellipsoid zone (EZ) parameters on OCT as calculated by a semiautomated computer algorithm with baseline visual acuity (VA) in eyes with retinal vein occlusion (RVO).
Ellipsoid zone on optical coherence tomography: a review
Despite the lack of consensus of the actual origin of the ellipsoid zone, there has been much interest in evaluating its integrity and intensity in different disease processes. This review paper aims to provide an overview of the ellipsoid zone and its clinical and research applications.
Automatic Three-dimensional Detection of Photoreceptor Ellipsoid Zone …
2016年5月9日 · In the SD-OCT image, the ellipsoid zone (EZ) 5, previously called the photoreceptor inner segment/outer segment (IS/OS), is defined as the second hyper-reflective zone of the outer retina and...
Reliability of Spectral-Domain OCT Ellipsoid Zone Area and Shape ...
We investigate the ellipsoid zone (EZ) area and EZ boundary shape measurement reliability and the operability characteristics of two methods of EZ boundary delineation in spectral-domain optical coherence tomography (SD-OCT).
Ellipsoid zone on optical coherence tomography: a review
2016年7月1日 · Investigating the relationship between ellipsoid zone (EZ) integrity on spectral domain optical coherence tomography (SD-OCT) and visual acuity revealed significant correlations between EZ integrity metrics and VA, and baseline EZ integrity metrics were predictive of future VA loss.
