Estimate Disc Area from the Heidelberg Spectralis OCT optic nerve report









---- === Test Procedure === 1. Obtain the Heidelberg Spectralis optic nerve report. The report must show an image of the optic nerve head and the superimposed peripapillary ring where peripapillary segmentation was performed.\\ {{::spectralis_oct_optic_nerve_report.png?|}}\\ 2. Measure ring diameter {{::spectralis_measure_ring.png?600|}}\\ 3. Measure horizontal optic nerve diameter {{::spectralis_horizontal_disc.png?600|}}\\ 4. Measure vertical optic nerve diameter {{::spectralis_vertical_disc.png?600|}} See [[optic_disc_area|Normative Data for Optic Disc Area]] {{tag>calculator optic_disc}}
