Abstract
Techniques are provided that detect the onset and/or progression of glaucoma from analyzing the area and or volume of suppression and inferior retinal nerve fiber layers.
Claims20
A method of analyzing retinal nerve fiber layer for detecting glaucoma and/or other retinal nerve fiber indicated eye conditions in a subject, the method comprising:
- collecting, using a glaucoma analysis processing device, retinal nerve fiber layer image data, the image data containing fiber layer thickness data for a region of interest of the retinal nerve fiber layer image data;
- segmenting, using a glaucoma analysis processing device, the retinal nerve fiber layer image data by removing retinal nerve fiber layer image data below a threshold thickness value over the region of interest, wherein segmenting the retinal nerve fiber layer image data segments a retinal region of interest;
- determining, using a glaucoma analysis processing device and from the segmented retinal nerve fiber layer image data, an area or a volume of the thickness of the retinal nerve fiber layer in the retinal region of interest;
- and
- determining, using a glaucoma analysis processing device and from the area or the volume, a severity of the glaucoma and/or at least one other of the other retinal nerve fiber indicated eye conditions for the subject.
2 more elements
A system comprising:
- one or more processors and one or more memories, the one or more memories storing instructions that when executed by the one or more processors, cause the one or more processors to;
- collect, retinal nerve fiber layer image data, the image data containing fiber layer thickness data for a region of interest of the retinal nerve fiber layer image data;
- segment the retinal nerve fiber layer image data by removing retinal nerve fiber layer image data below a threshold thickness value over the region of interest, wherein segmenting the retinal nerve fiber layer image data segments out a retinal thickness data region of interest ;
- determine, from the segmented retinal nerve fiber layer image data, an area or a volume of the desired retinal thickness data region of interest;
- and
- determine, from the area or the volume, a severity of glaucoma and/or at least one other retinal nerve fiber indicated eye condition for the subject.
3 more elements
An apparatus for analyzing retinal nerve fiber layers for detecting glaucoma and/or other retinal nerve fiber indicated eye conditions in a subject, the apparatus comprising:
- one or more processors and one or more memories, the one or more memories storing;
- a collecting module configured to collect, retinal nerve fiber layer image data, the image data containing fiber layer thickness data for a region of interest of the retinal nerve fiber layer image data;
- a segmenting module configured to segment the retinal nerve fiber layer image data by removing retinal nerve fiber layer image data below a threshold thickness value over the region of interest, wherein segmenting the retinal nerve fiber layer image data segments out a superior retinal thickness data region and an inferior retinal thickness data region;
- a determining module configured to determine, from the segmented retinal nerve fiber layer image data, an area or a volume of the superior retinal nerve fiber layer thickness data region and the inferior retinal nerve fiber layer thickness data region;
- and
- a diagnostic module configured to determine, from the area or the volume, a severity of glaucoma and/or at least one other retinal nerve fiber indicated eye condition for the subject.
