Purpose: To introduce a new retinal image processing technique powered by a retinal thickness analyzer (RTA, Talia, Neve-Ilan, Israel) and to report its findings.
Method: This is an observational study using RTA technology in patients with macular and retinal vascular disease. The RTA is a scanning laser biomicroscope using a Helium-Neon laser light source. The 3-D Anatomy Imager reconstructs a 3-D volume representation of the acquired cut section. The application allows free movement including zooming, rotation, and slicing of volume in three axes, as well as measurement of thickness and distance.
Results: The 3-D Anatomy Imager provides three-dimensional images of the posterior pole and the optic disc with clear linear lines. Retinal pathologies can be visualized in block sections from the vitreoretinal interface to the retinal pigment epithelium (e.g. cystic macular degeneration, macular hole, fibrous proliferations in the vitreoretinal interface).
Conclusions: The 3-D Anatomy Imager allows the processing of three-dimensional retinal images in a novel way. This promising technology is valuable in ascertaining retinal thickness, but limited in detecting the individual retinal component. Future technical changes will be designed to correct these limitations.
