Teaser image of the RetinaLyze Glaucoma software at work

RetinaLyze Glaucoma is a new algorithm, which is a part of the RetinaLyze web application. The RetinaLyze web application offers easy-to-use automated analysis of retinal images for early signs of Diabetic Retinopathy, AMD and Glaucoma as well as a built-in telemedicine solution.

Structure-function evaluation module.

Functionality of a retinal location obviously depends on the underlying anatomical structure of the retina in that location. One characteristic feature of glaucoma is that there is a close connection between sensitivity levels of given retinal locations (as described by visual field measurements) and anatomical structures related to the optic nerve head. The merit of PATH is that it provides an estimate of the retinal nerve fibre layer (RNFL) thickness around the optic nerve head and the relative area of the neuroretinal rim based solely on the results of visual field measurements performed with the SPARK examination strategy. This novel approach of predicting structure from function is made possible by the high reproducibility of the SPARK visual field exams.

The SPARK examination strategy was primarily developed for Glaucoma patients and is available for all OCULUS perimeters. It is based on data from more than 90,000 perimetric findings and allows a very fast, yet very precise measurement of thresholds in the central visual field.

TNT provides a quantitative, statistical analysis of the visual field examination results conducted over time.

Laguna ONhE

Optic Nerve Head Image System is a new method for measuring hemoglobin (Hb) levels at the optic nerve head (ONH) by means of color fundus images (exclusively with images obtained with the DEC 200) in order to achieve objective glaucoma diagnosis such as, scanning laser ophthalmoscopy (HRT),scanning laser polarimetry (GDx), and optical coherence tomography (OCT) and which can be combined with subjective visual field evaluation.
