OCT - THE GOLD STANDARD IN DIGITAL IMAGE PROCESSING

The OCT is used to diagnosis and monitor the Retinal Nerve Fiber Layer inside the eye.

The OCT technology provides digital image processing to accurately measure the retinal nerve fiber layer.  The OCT incorporates optical coherence tomography technology to provide comprehensive imaging and measurement of glaucoma and retinal disease.  The OCT is the gold standard in vivo imaging device for the posterior segment and offers proven reproducibility for disease diagnosis and managment.

The OCT provides real-time cross-sectional images and quantitative analysis of retinal features to optimize the diagnosis and monitoring of retinal disease and for pre- and post-therapy assessment.  The device is beneficial for evaluation of cataract patients, pre-and post-operatively, and for the assesment of early signs of glaucoma and retinal disease.

Retinal Nerve Fiber Layer (RNFL) Analysis
Circular scans around the optic nerve head capture RNFL measurement of the peripapillary region.  Analyses provide comparison of measurements to a normative database, demonstration of asymmetry and serial analysis.

 

Optic Head Analysis
Radial line scans through the optic disc create cross-sectional and topographical data.  The key analysis parameters include cup-to-disc ratios and horizontal integrated rim volume.

 

Macular Thickness Analysis
Radial line scans provide cross-sectional images and analyses revealing retinal layers and macular condition.  The change analysis feature illustrates change over time which is important when monitoring disease progression.

 

The OCT...An Important Diagnostic Tool for Children and Adults
Studies reveal that more than 40% of the optic nerve axons can be damaged before glaucomatous changes are detectable using traditional diagnostic methods.  The OCT is a useful resource in early identificaiton and, thus, treatment of glaucoma (and other retinal diseases) before functional changes and vision loss occur.

A 2005 study of children 3 to 17 years of age revealed that the differences between normal and glaucomatous eyes are present at very young ages.  The differences found in children are similar to those reported in adult studies.
