2015年11月21日 · 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 recovery of the EZ integrity is associated with the improvement in the mfERG implicit time, particularly at the central and temporal retina.

2019年2月25日 · 光学相干断层扫描仪--Optical Coherence Tomography（OCT）是一种利用弱相干光干涉仪的基本原理，检测生物组织不同深度层面对入射弱相干光的背向反射或几次散射信号，通过扫描，得到生物组织结构断层图像。 OCT 是一种非侵入性的眼底影像学检查设备，原理类似于B超对眼底进行断层扫描，是目前世界上最先进的眼底病变检查设备。 OCT对眼底病的诊断及病情监测变得越来越重要，且逐渐成为某些眼底疾病诊断的金标准。 虽然 OCT 从发明至今才 …

The ellipsoid zone (EZ) has been identified as an important feature on OCT that has critical prognostic value in macular disorders. In this report, we describe a novel assessment tool for EZ integrity that provides visual and quantitative assessment across an OCT data set.

2015年8月21日 · OCT EZ can be expressed as a ratios of the EZ to the ELM.10–12 The intensity of the ELM layer is used as the reference value to control for the variation in the brightness of different OCT scans because the ELM is a non-neural layer, does not alter its intensity with age or the stage of degeneration and as it has a consis-

One of the highly reflective structures in the outer retina that can be detected on OCT is the inner segment ellipsoid zone (EZ; also known as the inner segment/outer segment [IS/OS] line). 16,17 This is an important anatomic landmark in RP as its disappearance marks the boundary between healthy and unhealthy retina. 18 The point where this ...

2023年4月3日 · The study aims to assess the thickness of the retinal outer nuclear layer (ONL), ellipsoid zone (EZ) and photoreceptor outer segment (POS) band in various macular regions and its associations...

Partial EZ attenuation (photoreceptor degradation) and total EZ attenuation (photoreceptor loss) describe the measured thickness between the EZ and RPE layers via OCT (EZ-RPE thickness).

Directional OCT techniques 48 may provide improved visualization of abnormally waveguiding photoreceptors within EZ lesions, and provide more accurate visualization of the lesion boundaries. 49 Finally, use of AO-OCT techniques may allow imaging the EZ layer at a resolution comparable to that of confocal AOSLO. 50–53 While it is not known how ...

2017年7月1日 · Patients underwent spectral-domain (SD)-OCT and OCT-A imaging at a single visit. SD-OCT data were analyzed using a novel OCT EZ-mapping software to obtain linear, area, and volumetric measurements of the EZ-retinal pigment …

2020年7月23日 · In intermediate age-related macular degeneration, there was reported reduction of EZ relative optical intensity on OCT, where the EZ remained continuous, suggesting that quantitative assessment of the relative EZ intensity may indicate disease severity and progression, and thus a potentially effective biomarker (Gin et al., 2017; Toprak et al ...
