Abstract
Official abstract text for this publication.
The present invention relates to structural analysis of the optic nerve head (ONH). In one approach, a 3D volume of intensity data which includes the optic nerve head is acquired using an optical coherence tomography (OCT) system. The vitreoretinal interface (VRI) and the optic disc margin are identified from the 3D data. The minimum area of a surface from the optic disc margin to the VRI is determined. This minimum area can be displayed as an image or in the alternative, a value corresponding to this minimum area can be displayed. The minimum area measurement provides relevant clinical information to determine the health of the eye.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of evaluating the neuroretinal rim of a patient, said method comprising the steps of: acquiring a 3D volume of intensity data using an optical coherence tomography (OCT) device, said volume including the optic nerve head; identifying the vitreoretinal interface (VRI) from the 3D data; defining an optic disc margin from the 3D data; determining a value corresponding to the minimum area of a 3D surface between the optic disc margin and the VRI;…
