Webtomography (OCT) scanning patterns to extract images, generating different views from multiple parts of the retina. These images are used to measure the thickness of the retinal layers in different regions. Methods: We present two approaches for the multi-region segmentation of the retinal layers in OCT images of glaucoma patients. WebThe health of the optic nerve may be assessed through the evaluation of the retinal nerve fiber layer (RNFL), a well-established clinical and investigational tool. 4 Studies using either scanning laser polarimetry (SLP) 5–7 or optical coherence tomography (OCT) 8,9 have associated DM with thinning of the RNFL.
