Optic disc area in different types of glaucoma. [PDF]

open access: yesInt J Ophthalmol, 2016
To evaluate the possible relationship of optic disc area with retina nerve fiber layer in different glaucoma subtypes.One eye each was chosen from 45 patients with ocular hypertension, 45 patients with primary open angle glaucoma, 45 patients with pseudoexfoliation glaucoma and 45 healthy controls followed in our hospital.

Comparative analysis of RNFL and optic disc measurements across three OCT devices in healthy eyes: Implications for device standardization and clinical practice [PDF]

open access: yesIndian Journal of Ophthalmology
Purpose: The study aimed to compare retinal nerve fiber layer (RNFL) and optic disc measurements obtained using three optical coherence tomography (OCT) devices—Heidelberg Spectralis, Zeiss Cirrus 5000, and Optovue Solix Essential—in healthy individuals,

A Small Disc Area Is a Risk Factor for Visual Field Loss Progression in Primary Open-Angle Glaucoma: The Glaucoma Stereo Analysis Study [PDF]

open access: yesJournal of Ophthalmology, 2018
Purpose. The Glaucoma Stereo Analysis Study, a cross-sectional multicenter collaborative study, used a stereo fundus camera (nonmyd WX) to assess various morphological parameters of the optic nerve head (ONH) in glaucoma patients.

Exhausting an area with discs [PDF]

open access: yesProceedings of the American Mathematical Society, 1974
The general question is, just how much of a given area may be covered by interior disjoint discs? We simplify matters by choosing the unit square as our given area, and then give estimates (upper and lower) on how much of it may be so covered by

Area Minimizing Discs in Metric Spaces [PDF]

open access: yesArchive for Rational Mechanics and Analysis, 2016
We solve the classical problem of Plateau in the setting of proper metric spaces. Precisely, we prove that among all disc-type surfaces with prescribed Jordan boundary in a proper metric space there exists an area minimizing disc which moreover has a quasi-conformal parametrization.

Evaluation of subjects with a moderate cup to disc ratio using optical coherence tomography and Heidelberg retina tomograph 3: Impact of the disc area

open access: yesIndian Journal of Ophthalmology, 2015
Aim: The aim was to evaluate subjects with a moderate cup to disc ratio using optical coherence tomograph (OCT) and Heidelberg retina tomograph (HRT) 3. Settings and Design: We included 80 patients with early glaucoma and 80 nonglaucomatous subjects with
