The OCT Glaucoma Staging System was created based on data obtained from Nidek RS 3000 spectral-domain (sd)-OCT. This system uses the superior and inferior quadrant RNFL thickness values, plotted on an x – y diagram for staging structural damage severity in glaucoma.

Feb 15, 2020 · OCT devices use either conventional graphs of RNFL thickness in the TSNIT sequence, or the alternative approach championed by Donald Hood, MD, which places the temporal segment (more vulnerable in glaucoma) in the center of the graph.

Macular evaluation on OCT involves analysis of the ganglion cell - internal plexiform layer (GC-IPL) thickness, as well as analysis of the ganglion cell complex (GCC) that encompasses the RNFL, GC, and IPL.

Providing the high resolution OCT images and clinically useful analyses, the RS-3000 Lite achieves the optimum balance between cost and performance with its fundus surface imaging system. The RS-3000 Lite has been developed for

The OCT Glaucoma Staging System classifies RNFL defects into 6 stages of increasing severity ranging from borderline to stage 5, and 3 groups according to defect localization (superior, inferior, or diffuse).

GCC analysis evaluates the inner layers of the retina and includes GCL, IPL and facultative mRNFL (depending on the OCT machine). There are different acquisition settings available for the evaluation of GCC using the SD-OCT. They have distinct methods for …

Using OCT ONH scan to analyse peripapillary RNFL is now a widely employed parameter for diagnosing glaucoma. More recently, the measurement of the perimacular ganglion cell layer has emerged as a new diagnostic parameter in glaucoma with spectral domain OCT.

NIDEK is proud to announce its first release of advanced spectral domain OCT/confocal ophthalmoscope system, RS-3000 OCT "RetinaScan". The RS-3000 is the high-speed spectral domain OCT with the tradition of NIDEK, advanced auto-focus/auto Z alignment technology offers the combination of Precision and Ease-of-Use. Max. 50 image averaging 53, 000

Both white-white and SWAP visual fields have mild changes, generalized depression of sensitivity and enlargement of the blind-spot. TSNIT Graph. A mild superotemporal defect is evident in blue while a wide localized defect is evident inferotemporally in the [NFL+GCL+IPL] thickness map.

Mar 5, 2020 · Normative databases of optical coherence tomography (OCT) metrics, such as retinal nerve fiber layer (RNFL) and macular thickness, are critical to clinical use of OCT imaging. In order to accurately represent the range of normal variation in patient populations, these normative databases must themselves be adequately diverse.
