Computationally Efficient Optic Nerve Head Detection in Retinal Fundus Images [PDF]

Biomedical Signal Processing and Control Volume 11, May 2014, 2019
This paper presents a computationally efficient method for the detection of optic nerve head in both color fundus and fluorescein angiography images. It involves a combination of Radon transformation and multi-overlapping windows within an optimization framework in order to achieve a robust detection in the presence of various structural, color, and ...

Metabolic Dysfunction in New‐Onset Idiopathic Intracranial Hypertension: Identification of Novel Biomarkers

Annals of Neurology, Volume 96, Issue 3, Page 595-607, September 2024.
Objective Idiopathic intracranial hypertension (IIH) is a neurometabolic disease with an increasing incidence. The pathophysiology is unknown, but improvement of diagnosis and management requires discovery of novel biomarkers. Our objective was to identify such candidate biomarkers in IIH, and secondarily, test for associations between identified ...

Fully Convolutional Networks for Monocular Retinal Depth Estimation and Optic Disc-Cup Segmentation [PDF]

arXiv, 2019
Glaucoma is a serious ocular disorder for which the screening and diagnosis are carried out by the examination of the optic nerve head (ONH). The color fundus image (CFI) is the most common modality used for ocular screening.

Describing the Structural Phenotype of the Glaucomatous Optic Nerve Head Using Artificial Intelligence [PDF]

arXiv, 2020
The optic nerve head (ONH) typically experiences complex neural- and connective-tissue structural changes with the development and progression of glaucoma, and monitoring these changes could be critical for improved diagnosis and prognosis in the glaucoma clinic.

The prevalence of glaucoma in a 70‐year‐old Swedish population in the city area of Gothenburg

Acta Ophthalmologica, Volume 102, Issue 2, Page 208-215, March 2024.
Abstract Purpose To determine the prevalence of and risk factors for open‐angle glaucoma in a population of 70‐year‐olds in Gothenburg, Sweden and to compare the visual function between the glaucoma population and the non‐glaucoma population. Methods Of the entire cohort (n = 1203), 1182 participants responded a questionnaire on self‐reported glaucoma ...

DRUNET: A Dilated-Residual U-Net Deep Learning Network to Digitally Stain Optic Nerve Head Tissues in Optical Coherence Tomography Images [PDF]

arXiv, 2018
Given that the neural and connective tissues of the optic nerve head (ONH) exhibit complex morphological changes with the development and progression of glaucoma, their simultaneous isolation from optical coherence tomography (OCT) images may be of great interest for the clinical diagnosis and management of this pathology. A deep learning algorithm was

A Deep Learning Approach to Digitally Stain Optical Coherence Tomography Images of the Optic Nerve Head [PDF]

arXiv, 2017
Purpose: To develop a deep learning approach to digitally-stain optical coherence tomography (OCT) images of the optic nerve head (ONH). Methods: A horizontal B-scan was acquired through the center of the ONH using OCT (Spectralis) for 1 eye of each of 100 subjects (40 normal & 60 glaucoma). All images were enhanced using adaptive compensation.
