8137271System and method for assessing risk of glaucoma onset
A system and method for predicting the onset of glaucoma uses a Finite Element Model (FEM) to obtain a response profile of the Optical Nerve Head (ONH) inside an eye. To do this, the FEM is programmed with data from first and second images of the ONH that are respec...
