Avanti

Wide-field En Face OCT

The Avanti SD-OCT allows eye care practitioners at all levels to offer the most current technology and stay ahead of clinical challenges with confidence. The forward-thinking development encompassed in the Avanti also provides clinicians with the basis to move to the next level in clinical OCT utility... functional OCT.

About Avanti

The new standard in OCT imaging

The Avanti offers 40° wide-field, En Face OCT with multi-layered assessment of peripheral pathologies, breaking new standards in advanced OCT platforms.

The system offers Motion Correction Technology (MCT), 2-phase noise reduction, real-time tracking and deep choroidal imaging, as standard.

About Avanti

Motion Correction Technology (MCT)

Motion Correction Technology (MCT) applies proprietary algorithms to 3D data, to reduce or remove artifacts caused by eye motion during scanning. 3D scans in OCT systems are the most time consuming, so the most prone to motion artifacts. The Avanti offers SMART MCT which boasts a 3D cube of 320 x 320 (104 million data points) over a 12mm x 9mm area of the retina, with little or no motion artifacts.

About Avanti

2-phase noise reduction

2-Phase noise reduction in the Avanti FD-OCT system reduces signal noise both during the scan acquisition and post processing of the data captured. This allows for higher contrast in both the choroid and vitreous for optimum visualisation of structures.

About Avanti

Deep Choroidal Imaging (DCI)

Deep Choroidal Imaging (DCI) pushes the signal strength into the choroid area of the retina at the click of a button. 2-phase Noise Reduction Technology (NRT) ensures that your scans are as much real tissue signal as possible, while minimising noise masquerading as tissue. A 3mm scan depth and SharpVue technology provide visualisation and measurement from the choroid well into the vitreous. The VTRAC repeat mode allows the clinician to assess changes in structure with a high level of confidence.

Retinal documentation & monitoring

Retina module

The Avanti Retina Module gives retina specialists new information on structures outside the traditional 6mm x 6mm cube. It provides assessment of individual layers of the retina, offers views of the vitreous and deep choroid and enables evaluation of change over time.

Retinal documentation & monitoring

Range of scans

The Avanti offers a vast selection of retina scans including; Line,HD line, cross line, grid, raster, retina map, 3D retina, 3D wide-field and 3D wide-field with MCT. The HD line scan provides a high-density 12mm scan and presentation option for enhanced vitreous or choroid viewing.

Retinal documentation & monitoring

Analysis reports

The new Retina Map Change Analysis report provides a trend analysis of both the foveal thickness and macula volume over the course of the patient visit history.The multi-layered En Face report presents a user defined sampling of segmented slices, in high contrast 2D En Face summed images. 

A user selectable default is available for assessment of retina surface, neuro-sensory, retina pigment epithelium and choroid. A 3mm scan depth in a 12mm x 9mm volume scan provides visualisation of structures from deep choroid well into the vitreous. This is an asset when documenting long axial length or high myopic eyes.

Optic nerve & GCC assessment

Glaucoma module

The Avanti Retina Module gives retina specialists new information on structures outside the traditional 6mm x 6mm cube. It provides assessment of individual layers of the retina, offers views of the vitreous and deep choroid and enables evaluation of change over time.

Optic nerve & GCC assessment

Range of scans

Avanti offers Ganglion Cell Complex (GCC), Optic Nerve Hypoplasia (ONH) and 3D disc scans for the assessment and monitoring of glaucoma.

Optovue’s robust proprietary algorithms allow confident assessment of the optic nerve head and retinal nerve fibre. Comparison to a large normative database is provided for the Retinal Nerve Fibre Layer (RNFL) sampling and optic disc parameters.

Optic nerve & GCC assessment

Normative database & comparison

A Normative Database (NDB) comparison reference is provided for the retinal nerve fibre layer, optic disc and Ganglion Cell Complex (GCC). This includes FLV (Focal Loss Volume) and an NDB comparison summary table which provides a quick reference to metrics flagged as borderline or outside normal limits.

Optic nerve & GCC assessment

Ganglion Cell Complex (GCC)

Ganglion Cell Complex (GCC) Analysis was introduced to eyecare by Optovue in 2007. Seven years of clinical studies have shown Optovue to be the leader in developing and expanding the clinical utility of OCT technology. Focal Loss Volume (FLV) & Global Loss Volume (GLV) are exclusive and proprietary analysis that increase the specificity and sensitivity of the GCC analysis.

Optic nerve & GCC assessment

Simplify your evaluation process

The nerve fibre change summary report with the new trend analysis provides the most comprehensive presentation of data to simplify your evaluation process.  Proprietary algorithms determine the optic disc margin and vessel patterns to ensure a reliable RNFL and optic disc change-over-time assessment.

Optic nerve & GCC assessment

Trend analysis

Trend Analysis provides assessment of the rate of change for retinal nerve fibre and Ganglion Cell Complex structure. No highlighting of the p-value indicates that there is no statistically significant change over time.  Light purple with black numbers indicates that the change over time is borderline statistically significant. Dark purple with white numbers indicates that change over time is statistically significant.

Optic nerve & GCC assessment

Optic disc structure analysis & widefield En Face mapping

Optic disc structure analysis offers a high detail structural examination of the optic disc with cross line B-scans.  This allows the clinician to determine whether the changes over time are statistically significant.  Avanti also offers widefield En Face mapping. This is a convenient and quicker assessment of orientation when evaluating RNFL and GCC results.

Anterior segment assessment

Visualisation & measurement

The Avanti anterior segment module expands the clinical utility of your OCT to address a broad range of patients in the practice. This comprehensive package includes exciting new technology as well as the standard features you’ve come to expect from anterior segment OCT. Avanti wide-field OCT offers a new way to calculate IOL powers and to assess the thickness of the epithelium, while also providing essential functions such as cornea cross-line scans, angle measurement and pachymetry.

Anterior segment assessment

Total Corneal Power (TCP)

Total Corneal Power (TCP) provides direct quantification of the corneal power by measuring both the front and the back surfaces of the cornea. Scan acquisition takes less than two seconds and renders historical data unnecessary.  Data points are entered into the ASCRS online IOL calculator to generate recommended lens power.

Anterior segment assessment

Pachymetry & angle measurement

The Avanti offers a non-contact anterior segment assessment with full 6mm diameter corneal thickness mapping and a minimum thickness indicator.

It also boasts a non-contact method for measuring and assessing the angle.  It allows the user to produce both change and OU reports.

Anterior segment assessment

Epithelial Thickness Mapping (ETM)

The Avanti anterior segment module offers a 6mm diameter epithelial thickness map with minimum thickness marker. Epithelial Thickness Mapping (ETM) aids the clinician in evaluating potential Keratoconus, LASIK/LASEK/PRK planning, tracking epithelial regrowth,dry eye and contact lens patients.
