Glaucoma Detection from Color Fundus Images [PDF]

, 2020
Glaucoma is a pathological condition, progressive neurodegeneration of the optic nerve, which causes vision loss. The damage to the optic nerve occurs due to the increase in pressure within the eye.

Integrated approach for accurate localization of optic disc and macula [PDF]

, 2014
The location of three main anatomical structures in the retina namely the optic disc, the vascular arch, and the macula is significant for the analysis of retinal images.

The Relationship of the Clinical Disc Margin and Bruch's Membrane Opening in Normal and Glaucoma Subjects. [PDF]

, 2016
PurposeWe tested the hypotheses that the mismatch between the clinical disc margin (CDM) and Bruch's membrane opening (BMO) is a function of BMO area (BMOA) and is affected by the presence of glaucoma.MethodsA total of 45 normal eyes (45 subjects) and 53

Unilateral situs inversus of optic disc associated with reduced binocularity and stereoacuity resembling monofixation syndrome

Indian Journal of Ophthalmology, 2010
Situs inversus of the optic disc is a rare, usually bilateral, congenital embryological abnormality associated with high myopia, optic disc coloboma or tilted optic disc.

Multicolor imaging in optic disc swelling

Indian Journal of Ophthalmology, 2017
Differentiating optic disc edema (ODE) from pseudo optic disc edema (PODE) continues to pose a diagnostic dilemma. Current report highlights the role of multicolor imaging (MC) in differentiating ODE from PODE.

Flatness in disc galaxy dynamics without MOND or dark matter [PDF]

arXiv, 2004
In previous work (astro-ph/0306228) we have established that a particular quasi-classical theoretical viewpoint about the nature of gravitation in galaxy discs provides extremely high concordance (comparable with MOND) with the observed dynamics in optical discs. In this paper, we consider the possibility that the optical disc and the flat radio disc

From 2D to 3D gamma passing rate tolerance and action limits for patient‐specific quality assurance in volumetric‐modulated arc therapy

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Background Volumetric modulated arc therapy (VMAT) requires an accurate patient‐specific quality assurance (PSQA) program. In clinical practice, this is usually performed using the γ‐index and the two‐dimensional gamma passing rate (2D %GP). A three‐dimensional (3D) index incorporating the patient anatomy could be more useful for the 3D dose ...

Unilateral Optic Disc Neovascularization in a Patient with Optic Disc Pit Depending on Proliferative Diabetic Retinopathy

Bezmiâlem Science
Optic disc pit is an excavation of the optic disc that usually develops congenital or rarely acquired, mostly located in the inferotemporal part of the disc. It is usually asymptomatic but sometimes might be symptomathic with maculopathy development.
