MENINGOCOELE OF THE OPTIC DISC [PDF]
British Journal of Ophthalmology, 1960 A fit young man aged 26 was examined on June 13, 1959, to assess his suitability for service with the Royal Air Force. He was an experienced pilot with a total of 250 hours flying experience in all types of aircraft, including jets. No abnormality had been detected in any system at a previous examination. Examination.-Visual acuity in the right eye was

BMC 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

Optic Disc and Cup Segmentation Methods for Glaucoma Detection with Modification of U-Net Convolutional Neural Network [PDF]
Pattern Recognition and Image Analysis, 2017 Glaucoma is the second leading cause of blindness all over the world, with approximately 60 million cases reported worldwide in 2010. If undiagnosed in time, glaucoma causes irreversible damage to the optic nerve leading to blindness. The optic nerve head examination, which involves measurement of cup-to-disc ratio, is considered one of the most ...

Optical Coherence Tomography Angiography of the Optic Disc; an Overview [PDF]
Journal of Ophthalmic & Vision Research, 2017 Different diseases of the optic disc may be caused by or lead to abnormal vasculature at the optic nerve head. Optical coherence tomography angiography (OCTA) is a novel technology that provides high resolution mapping of the retinal and optic disc ...

British Journal of Ophthalmology, 1972 Background: Our studies had indicated that optic disc vasculitis (ODV) is a distinct clinical entity. We investigated the presentation and clinical characteristics of ODV and determined the efficacy of systemic corticosteroids in its management. Methods: From 1973 to 1997, we investigated 32 patients (34 eyes) with ODV.

Association of optic disc pallor and RNFL thickness with cerebral small vessel disease in the PREVENT-Dementia study. [PDF]
Alzheimers Dement (Amst)INTRODUCTION: We tested associations between two retinal measures (optic disc pallor, peripapillary retinal nerve fiber layer [pRNFL] thickness) and four magnetic resonance imaging markers of cerebral small vessel disease (SVD; lacunes, microbleeds ...
