Beskrivelse

Topcon’s 3D imaging and analysis functions provide invaluable pathological confirmation of progression. With the addition of noise reducing algorithms and Infra red/3D tracking technology, the 3D OCT-2000 provides you with extremely detailed OCT images.

Fundus Images
Unique to the Topcon OCT series is its integrated retinal photography function, which is based upon its highly successful non-mydriatic fundus camera. An interchangeable (future proof) 16.2mp digital camera acquires highly detailed images using a sub one millisecond flash at the point of OCT capture or stand alone fundus photography if required.

Glaucoma
One of many modules within Topcon’s Fastmap software; The Glaucoma module allows fully automated disc topography, normative database comparison and total progression analysis (trend analysis) through various screening options. Complemented by Ganglion cell analysis and anterior chamber angle measurements the glaucoma module is a comprehensive screening tool.

Anterior segment scanning
By combining both OCT scan technology with traditional photographic imaging a variety of analysis functions and scan protocols allow for the detection and treatment of many corneal conditions. Full corneal thickness topography and automated central thickness values are complemented by corneal curvature topography along with high resolution imaging.

Case study
The website "Retina Revealed," publishes a weekly, thought-provoking series providing doctors/clinicians with the latest technology in Retina via online case presentations.
In this case the Topcon 3D OCT-2000 reveals the actual location and third dimensional extent of a subhyaliod hemorrhage, a micro-aneurysm and disc neovascularisation.
