Retinal nerve fiber layer - Wikipedia
The retinal nerve fiber layer (RNFL) or nerve fiber layer, stratum opticum, is part of the anatomy of the eye. The RNFL formed by the expansion of the fibers of the optic nerve; it is thickest near the optic disc, gradually diminishing toward the ora serrata.
RNFL Analysis in the Diagnosis of Glaucoma
RNFL analysis is an extremely helpful tool for the management of glaucoma patients. It can be used in conjunction with other examination findings and diagnostic imaging tools to diagnose early or preperimetric cases, and the quantitative nature of these measurements is useful for monitoring disease progression.
Optic Nerve and Retinal Nerve Fiber Imaging - EyeWiki
OCT imaging of the RNFL, ONH, and macula has been employed as a tool to aid in the diagnosis of glaucoma. A series of devices have been manufactured to analyze each of these components. Studies have demonstrated the high analytical and diagnostic performance of OCT imaging of the RNFL, ONH, and macula for the recognition of glaucomatous and non ...
Retinal Nerve Fiber Layer - an overview | ScienceDirect Topics
The circumpapillary retinal nerve fiber layer (RNFL) represents the axons of the optic nerve that are adjacent to the optic disc before their entering the nerve. From: Neuroimaging Clinics of North America, 2015
RNFL正常值范围 - 有来医生
2023年2月14日 · RNFL在临床上不仅可以提示眼底病变，也是青光眼的早期诊断依据，可通过光学相干断层成像的视乳头扫描分析得出RNFL数值，提示青光眼等疾病是否发生。 若检查发现RNFL数值稍低，可能提示纤维层略微变薄，当RNFL水平明显降低时，提示视网膜神经纤维层可能出现病理性改变，需及时就医处理。 如果RNFL显著升高，可能提示视网膜神经纤维存在水肿、充血，甚至出血等异常情况，还需判断视网膜下是否存在积液。 若患者出现RNFL指标的异常， …
Retinal Nerve Fiber Layer Optical Texture Analysis - EyeWiki
Recently, Leung et al. have developed a new parameter known as RNFL Optical Texture Analysis (ROTA), which may be more accurate in detecting these RNFL defects. How does ROTA’s algorithm work? ROTA’s algorithm gathers RNFL thickness and RNFL reflectance measurements from a standard OCT scan.
Rates of retinal nerve fiber layer thinning in glaucoma suspect …
Global and quadrant RNFL thickness (RNFLT) were measured with the Spectralis spectral-domain optical coherence tomography (SD-OCT). VFD was defined as having 3 consecutive abnormal visual fields. The rate of RNFL loss in eyes developing VFD was compared with eyes not developing VFD using multivariable linear mixed-effects models.
Imaging of the Optic Nerve and Retinal Nerve Fiber Layer: an …
Wedge shaped thinning of the retinal nerve fiber layer (RNFL; red zones in the RNFL Deviation Map) are evident in the superior and inferior regions in the right eye. RNFL Thickness profile also demonstrates localized thinning in the same regions.
Analysis of normal retinal nerve fiber layer thickness by age ... - PubMed
The thickest RNFL measurements were found in the inferior quadrant, followed by the superior, nasal, and temporal quadrants (ISNT rule applied to the RNFL). Thinner RNFL measurements were associated with older age and increasing myopia. Caucasians tend to have thinner RNFL values when compared with …
Retinal Nerve Fiber Layer Progression in Glaucoma
Examination of retinal nerve fiber layer (RNFL) defects and monitoring of their progression are key components in glaucoma management.
