Objective
Optical coherence tomography (OCT, Stratus© OCT Zeiss) is a noninvasive, noncontact, transpupillary imaging technology which can image retinal structures. Cross-sectional images of the retina are produced routinely in 2 dimensions. Since most ophthalmological problems deal with 3-dimensions, analyzing in 3D is a very important skill to master.
Methods
The appearance of a variety of posterior segment pathologies were exemined with OCT (Carl Zeiss Ophthalmic Systems, Inc.Humphrey Division). The software "OCT-3D" enabled direct and full access to the original OCT-database. The program icludes several process steps: digital picture improvement, automatic alignement, creating a 3D model based on the interpolation of structural data.
Results
3D-view manipulation and visualisation is made easy with OCT-3D. The data provided by OCT-3D can be exported as single image or as automatically generated video file in all generally used format. Multiple process steps do not need to be called separately but are run from using individual pipelines.
Conclusions
OCT-3D is a new self running software tool which is designed to facilitate the presentation and analysis of retinal and macular disease. In addition to the well known 2-dimensional images a dynamic 3-dimensional lesion reconstruction method is provided now. The innovative archive system gives a rapid and simple way of updating archive files providing data integrity resulting in saving time and money. Much of the software was designed to allow for content updates, without modifications to the application itself.
