Specifications for Stratus OCT
This is NOT old technology! Stratus gives you the same basic information and receives the same reimbursement, with the exception of anterior segment imaging.
Stratus OCT provides a higher level of diagnostic insight – a significant contribution to therapeutic confidence across a broad spectrum of ophthalmic diseases. Using near-infrared frequency light, Stratus OCT reveals an in vivo crosssectional view with an axial resolution of 10 μm, and quantitative analysis of the retinal layers.
In the Stratus OCT image display, retinal layers with the highest reflectivity appear red. In a healthy retina, these include the nerve fiber layer, retinal pigment epithelium and choriocapillaris. The layers that exhibit minimal reflectivity appear blue or black, such as the photoreceptor layer, choroid, vitreous fluid or blood.
Obtain real-time non-invasive histology of live tissue.
Stratus OCT reveals the retinal layers in high-resolution, cross-sectional views, offering insight for diagnosis,
therapy and ongoing management of retinal disorders.
Visualize and analyze retinal disorders.
- Stratus OCT reveals and measures diffuse macular thickening and loss of foveal contour
- Intraretinal cysts and fluid accumulation are identifiable as areas of low reflectivity in the cross-sectional scan
- Post-treatment resolution of retinal thickening can be quantified and monitored
- Stratus OCT scan shows the epiretinal membrane as a highly reflective band on the inner retinal surface
- Separation of the membrane from the retina is visible in areas
- Underlying retina is thickened, with loss of normal foveal contour
Age-related Macular Degeneration
- Disruption of RPE, caused by neovascularization and drusen, can be visualized
- Pockets of interretinal fluid are visible as areas of reduced reflectivity
- Structural changes resulting from therapy can be quantified and monitored
Detect glaucoma damage at an early stage
Retinal Nerve Fiber Layer Analysis
- Analysis of RNFL aids in identification of early glaucomatous loss
- Circular scans of 3.4 mm diameter around optic nerve head provide measurement of RNFL in the peripapillary region
- RNFL thickness measurement is graphed in a TSNIT orientation and compared to age-matched normative data
Optic Nerve Head Analysis
- Radial line scans through optic disc provide crosssectional information on cupping and neuroretinal rim area
- Disc margins are objectively identified using signal from end of RPE
- Key parameters include cup-to-disc ratio and horizontal integrated rim volume1
Macular Thickness Analysis
- Thinning of the macula may reflect glaucomatous loss
- Structural analysis of retinal sublayers reveals macular complications
- Cross-sectional view provides visualization and measurement of retinal layers
