Conformal geometry of the retinal nerve fiber layer [PDF]

open access: yesProceedings of the National Academy of Sciences, 2008
The nerve fiber layer of the human retina is made up of the retinal segments of ganglion cell axons. Its geometry can be described mathematically as a fibration of a 2D domain: a partition of a certain region into smooth curves. Here, we present a simple family of curves that closely models the observed geometry of the nerve fiber ...

Optical coherence tomographic findings in optic nerve hypoplasia

open access: yesIndian Journal of Ophthalmology, 2013
We investigated a case of unilateral optic nerve hypoplasia using spectral domain optical coherence tomography (SDOCT). Optical coherence tomography was done on both eyes using 5-line Raster scan for the fovea to analyze the retinal nerve fiber layer ...

Application of Structural Retinal Biomarkers to Detect Cognitive Impairment in a Primary Care Setting

open access: yesJournal of Alzheimer's Disease Reports, 2022
Background: Despite the diagnostic accuracy of advanced neurodiagnostic procedures, the detection of Alzheimer’s disease (AD) remains poor in primary care. There is an urgent need for screening tools to aid in the detection of early AD.

Diagnostic ability of retinal nerve fiber layer maps to detect localized retinal nerve fiber layer defects [PDF]

open access: yesEye, 2013
To evaluate and compare the diagnostic ability of spectral domain optical coherence tomography (SD-OCT) for detecting localized retinal nerve fiber layer (RNFL) defects in topographic RNFL maps and circumpapillary RNFL (cpRNFL) thickness measurements.Sixty-four eyes with localized RNFL defects in red-free RNFL photographs and 72 healthy eyes were ...

Macular and retinal nerve fiber layer thickness changes after small-incision lenticule extraction and femto-LASIK

open access: yesDelta Journal of Ophthalmology, 2015
Introduction Femtosecond laser flap creation exerts less intraocular pressure (IOP) fluctuation but requires more procedural time compared with microkeratome flap creation.
