Joint optic disc and cup segmentation based on densely connected depthwise separable convolution deep network

open access: yesBMC Medical Imaging, 2021
Background Glaucoma is an eye disease that causes vision loss and even blindness. The cup to disc ratio (CDR) is an important indicator for glaucoma screening and diagnosis. Accurate segmentation for the optic disc and cup helps obtain CDR. Although many

Cup-to-Disc Ratio in Idiopathic Intracranial Hypertension without Papilloedema. [PDF]

open access: yesNeuroophthalmology, 2014
This study seeks to characterise potential differences in the cup-to-disc ratio (CDR) of patients with idiopathic intracranial hypertension (IIH) with papilloedema (IIHWP) compared with IIH without papilloedema (IIHWOP). The medical charts, optical coherence tomography (OCT), and digital optic disc photos of 30 patients (59 eyes) with IIHWP and 4 ...
