Description

Overview

RETINA

Single 3D Retina examination is enough to perform both Retina and Glaucoma analysis based on retinal scans. Software automatically recognize 8  retina layers. Thus allowing a more precise diagnosis and mapping any changes in the patient’s retina condition.

OCT Angiography

This optional software module allows visualization of the retinal microvasculature. Angiography SOCT is a non-invasive, dye-free technique providing 3D image of retinal blood circulation.
Software allows to observe, track and compare changes in the microvasculature of the retina in both eyes.

ANGIO ANALYISIS METHODS

QUANTIFICATION

The quantification tool provides quantification of the vasculature in the whole analyzed area together with values in specific zones and sectors. Thanks to the heat map of the analyzed vasculature the evaluation of vascular structure conditions is much faster. The choice of the quantification method increases the sensitivity of analyses for specific deseases.

Available quantification methods:

• Vessel Area Density – it is defined as the total area of perfused vasculature per unit area in a region of measurement.
• Skeleton Area Density – it is defined as the total area of skeletonized vasculature per unit area in a region of measurement.

Quantification is available for a specific layer in Angio OCT exam:

• Retina: Superficial Plexus and Deep Plexus
• Disc: RPC – Radial Peripapillary Capillary

ANGIO-ANALYTICAL TOOLS

FAZ – Foveal Avascular Zone measurements enable the quantification and monitoring of changes in Superficial and Deep vascular layers. The FAZ tool is also available for narrow and wide scans.

VFA – Vascular Flow Area allows the user to examine the pathologically affected area and to precisely measure the area covered by vascularization.
The simple and easy area measurement can be performed on a predefined or user-selected vascular layer.

NFA – Non Flow Area measurement tool makes it possible to quantify the Non Flow Area on the OCT Angio examination. It provides the sum of all marked areas.

ANGIO MOSAIC

The Angiography mosaic delivers high-detailed images over large field of the retina.
Advanced tab provides: view of any vascular layers, enface view of vascular layers, depth coded and thickness map. Mosaic modes: 10×6 mm, 12×5 mm, 7×7 mm, 10×10 mm and Manual (up to 12 images).

GLAUCOMA
Comprehensive glaucoma analytical tools for quantification of the Nerve Fiber Layer, Ganglion layer and Optic Head with DDLS allow for the precise diagnosis and monitoring of glaucoma over time.
With the golden standard 14 optic nerve parameters and a new Rim to Disc and Rim Absence the description of ONH condition is quick and precise.
Advanced view which provides combined information from Retina and Disc scan to integrate details of the Ganglion cells, RNFL, ONH in a wide field perspective for comprehensive analysis.

Advance Retina & ONH	ONH Single

Asymmetry Analysis of Ganglion layers between hemi-spheres and between eyes allows easier identification and detection of glaucoma in early stages and in non-typical patients.

Ganglion Both	Ganglion Progression

Implemented the DDLS  – Disc Damage Likelihood Scale which use 3 separate classification for small, average and large discs. It supports the practitioners in a quick and precise evaluation of the patient’s glaucomatous disc damages.

COMPLETE YOUR GLAUCOMA REPORT

To eliminate common problem with the understanding of the patient’s IOP pachymetry module provides IOP Correction value.  With the implemented Adjusted IOP formula you can quickly and precisely understand the measured IOP value.
As the Pachymetry and Anterior Chamber Angle Verification require no additional attachments, the predefined Glaucoma protocol, which consists of Retina, Disc and Anterior scans, can be done automatically to reduce patient chair time.

COMPREHENSIVE GLAUCOMA SOLUTION

STRUCTURE & FUNCTION – Combined OCT and VF results analysis

Invaluable combination of information about the functional quality of vision with comprehensive data on retinal Ganglion Cells, RNFL and Optic Nerve Head for both eyes on a single report page. The S&F report contains the following:

• VF sensitivity results (24-2/30-2 or 10-2)
• Total and Pattern Deviation probability graphs for VF results
• Reliability and Global indices for VF results
• Combined map of Structure & Function
• Ganglion cell analysis (GCL+IPL or NFL+GCL+IPL)
• ONH and NFL analysis including charts and comparison tables
• NFL Asymmetry Plot

The S&F report compares in a natural way the anatomical relationship between VF and RNFL/Ganglion maps.

Visually verify your measurement
All measurement calipers are shown on the all boundaries OCT image provided by REVO. Now, you can visually verify and correct what structure of the eye has been measured.

TOPOGRAPHY OCT is optional software module to purchase
T-OCT™ is a pioneering way to provide detailed corneal Curvature maps by using posterior dedicated OCT. Ante-rior, Posterior  surface and Corneal Thickness allow to provide the  True Net Curvature information. With Net power, the precise understading of the patient’s corneal condition comes easily and is free of errors associated with modelling of posterior surface of the cornea.  SOCT T-OCT module provides Axial maps, Tangential maps, Total Power map, Height maps, Epithelium and Corneal thickness maps.
Corneal topography module clearly shows the changes in the cornea on the difference map view. Customize your
Topography module provides:

• Full featured Corneal mapping of Anterior, Posterior and Real
• Precise Astigmatism Display Option (SimK: Anterior, Posterior, Real,  Meridian and Emi-Meridian ø 3, 5, 7 mm zones

KERATOCONUS SCREENING
