The purpose of the study was to evaluate the structure-function relationship and diagnostic value of retinal nerve fiber layer (RNFL) Area Index from the RNFL thickness deviation map of Cirrus SD-OCT.: A total of 84 normal control eyes, 88 preperimetric eyes, and 146 perimetric glaucoma eyes were analyzed.

Comparison of RNFL thickness and RPE-normalized RNFL attenuation coefficient for glaucoma diagnosis
SPIE Proceedings, 2013Recently, a method to determine the retinal nerve fiber layer (RNFL) attenuation coefficient, based on normalization on the retinal pigment epithelium, was introduced. In contrast to conventional RNFL thickness measures, this novel measure represents a scattering property of the RNFL tissue.

Peripapillary RNFL Thickness Changes after Panretinal Photocoagulation
Optometry and Vision Science, 2016ABSTRACT Purpose To evaluate changes in peripapillary retinal nerve fiber layer (RNFL) thickness as determined by spectral domain optical coherence tomography (SD-OCT) after panretinal photocoagulation (PRP) for proliferative diabetic retinopathy (PDR).

Glaucoma is an optic neuropathy characterized by progressive loss of retinal ganglion cells and their axons. Detection of glaucoma is based on the identification of abnormalities in the optic nerve head or the retinal nerve fiber layer (RNFL), either structural or functional.

Measuring primate RNFL thickness with OCT
IEEE Journal of Selected Topics in Quantum Electronics, 2001We report results of a study using optical coherence tomography (OCT) to create area maps of the retinal nerve fiber layer (RNFL) thickness. Low-resolution B scans (two-dimensional images) of the in vivo rhesus monkey retina have been recorded in the optic disk, peripapillary area, and macula. Three-dimensional (3-D) renderings of these areas have been

Agreement between spectral-domain and time-domain OCT for measuring RNFL thickness [PDF]
British Journal of Ophthalmology, 2009 To evaluate spectral-domain (SD) optical coherence tomography (OCT) reproducibility and assess the agreement between SD-OCT and Time-Domain (TD) OCT retinal nerve fibre layer (RNFL) measurements.Three Cirrus-SD-OCT scans and one Stratus-TD-OCT scan were obtained from Diagnostic Innovations in Glaucoma Study (DIGS) healthy participants and glaucoma ...

Genetic spectrum, retinal phenotype, and peripapillary RNFL thickness in RPGR heterozygotes
Graefe's Archive for Clinical and Experimental Ophthalmology, 2022Phenotypic heterogeneity with variable severity has been reported in female carriers of retinitis pigmentosa GTPase regulator (RPGR) mutations, including a male-type phenotype. A phenomenon not fully understood is peripapillary retinal nerve fiber layer (pRNFL) thickening in male patients with RPGR-associated X-linked retinitis pigmentosa, especially ...

Histologic RNFL Thickness in Glaucomatous Versus Normal Human Eyes
Journal of Glaucoma, 2016Purpose: To compare the retinal nerve fiber layer (RNFL) thickness in histologic sections of glaucomatous eyes to nonglaucomatous eyes, to ascertain whether RNFL thinning can be confirmed histologically in human eyes. Materials and Methods: Seven postmortem glaucomatous eyes were ...

Automated method for RNFL segmentation in spectral domain OCT
Proceedings of SPIE, 2008We introduce a method based on optical reflectivity changes to segment the retinal nerve fiber layer (RNFL) in images recorded using swept source spectral domain optical coherence tomography (OCT). The segmented image is used to determine the RNFL thickness.

RNFL — Die retinale Nervenfaserfotografie in der Glaukomfrühdiagnostik
Spektrum der Augenheilkunde, 1991Es wurden Nervenfaserfotografien von Patienten mit intraokularen Druckwerten von 21 mm Hg und daruber untersucht und mit den dazugehorigen Gesichtsfeldbefunden verglichen. Einerseits zeigte sich die eindeutige Korrelation zwischen Nervenfaserschichtdefekten und bereits korrespondierenden Gesichtsfeldverlusten, andererseits geht aus allen bisherigen ...
