Topcon

 3D OCT-2000 Spectral Domain OCT

 

High-resolution OCT

With years of experience in retinal imaging and a passion to produce the highest quality results, we have succeeded in producing our most stunning retinal image ever an overlap of up to 50! With just one click to change the reference mirror position to the choroidal mode, the border between choroid and sclera becomes apparent due to Enhanced Depth Imaging. Trust our newest of 3D OCT-2000 for better visualization and differentiation of each single layer.

Topcon’s 3D imaging and analysis functions provide invaluable pathological confirmation of progression, the true extent of oedema and the influence of vitreoretinal traction. Only Topcon 3D OCT can be your true surgical guide.

Easy Operation

With the combined multiple auto functions, no extra training is required to use Topcon 3D OCT-2000.
Images can be captured easily, accurately and immediately.

Easy Capturing
Intuitive scan protocol selection with auto functionality will increase workflow. You will be assisted with Auto Focus / Auto Shoot for retinal camera and Auto Focus / Auto Z&Z Lock / Auto Polarisation when shooting OCT.

Easy To Use Touch-Screen Panel
8.4” integrated touch screen LCD control panel for easy operation.
Less eye movement when picturing, since you can both navigate and picture by one screen without seeing the PC monitor every time.

Variable Analysis Modules

Retina

Compare Function
Exclusive 3D OCT FastMap™ software allows for dynamic visualisation of each eye on the same screen or serial exams from the same eyes.
The built in analysis tools illustrate the extent of oedema pre and post treatment, allowing simplistic methods to plan clinical care and track medical effectiveness.

8.2×3mm Wide View
3D OCT-2000 allows for wide area scans, allowing even the smallest area of pathology to be captured during initial scan.

Combination of Topcon 3D OCT & FA/FAF/ICG Images and More
Autofluorescence, Fluorescence Angiography and Indocyanine Green image is simply imported to allow pin point registration to aid the diagnosis of RPE and Choroidal changes.

Glaucoma

3D Tracking
The 3D tracking system (compensation function and rescanning function) reduces blurred images generated by the microsaccades, enabling you to obtain consistent quality images.
■Compensation Function
Automatically corrects the distortion due to microsaccades
■Rescanning Function
Automatically compensates by rescanning the area when microsaccades cause interference
RNFL Trend Analysis
□Change in RNFL Thickness
Change in the nerve fibre layer thickness can be monitored via RNFL Trend Analysis and comparison with normative data. Multiple patient visits can be viewed simply on one screen aiding disease management.
□Trend Analysis
Trend analysis can calculate linear regression lines by using all stored patient data. This chart can be useful to follow patient data as well as a useful patient education tool.
□Select an Icon
Total patient history data including overlay / thickness map / fundus image can now be shown on the same report.
[Acquirable Data] DA: Disc Area CA: Cup Area RA: Rim Area CV: Cup Volume RV: Rim Volume CDR: Cup to Disc Ratio LCDR: Linear Cup to Disc Ratio VDD: Vertical D.D HDD:Horizontal D.D
Disc Topography Module
Comprehensive normative database comparisons combined with C / D ration and topography maps can be displayed and analysed on a single screen or report.
Panoramic Fundus View
The mosaic function enables easy assessment of a vast area from macula to disc, providing a broader view of the fundus which can lead to faster detection and treatment for patients.

Anterior

■Get Quickly, Non-contact, High-resolution Anterior Image

 

Topcon 3D OCT-2000 not only gives you the posterior but also an anterior image, unmasking the precise shape and curvature of the cornea. Combined with rich analysis modules, you can easily detect any corneal disorders, such as corneal trauma, ulcer, astigmatism the rich analysis module is also good for pre and post refractive surgery observation.
Enjoy increased clinical efficiency with the enhanced Topcon 3D OCT.
