BACKGROUND To find the correlations and differences between the nerve fiber layer parameters of a GDx (polarimetric retinal nerve fiber analyzer) in single high quality images and those in the mean image from three high quality images. METHODS The results of scanning laser polarimetry were selected from 63 eyes of 63 patients (31 male and 32 female). Complete ophthalmic examinations included ...
Background: Modifications of the inner retinal layer is a frequent observation following pars plana vitectomy. Aim Work: To assess early changes thickness Retinal Nerve Fiber Layer after vitrectomy by ocular coherence tomography. Patients and Methods: This non-interventional observational study, in which 30 eyes patients underwent Examination Pars Plana Vitrectomy OCT. Cases were performed at O...
Purpose To evaluate macular and peripapillary vessel perfusion density (VD) in glaucoma suspects (GS) and glaucoma patients; to correlate ganglion cell-inner plexiform layer (GCIPL) and retinal nerve fiber layer (RNFL) thicknesses with macular and peripapillary VD; and to evaluate the diagnostic accuracy of the structural and vascular parameters. Methods A consecutive series of GS, glaucoma p...
The degree of polarization (DOP) of the light reflected from the optic nerve head has been assessed by means of a polarimetric scanning laser ophthalmoscope as a function of the age of the participants. Four fundus images corresponding to independent polarization states in the recording pathway were used to compute the spatially-resolved DOP. This was not uniform across the optic nerve head and...
PURPOSE To evaluate the reproducibility of the peripapillary retinal nerve fiber layer (RNFL) thickness measurements obtained by Spectralis spectral domain optical coherence tomography (OCT) (Heidelberg Engineering, Heidelberg, Germany) in normal and glaucoma participants. METHODS Participants were recruited from a university-based clinic. Peripapillary RNFL thickness measurements were repeat...
OBJECTIVE To assess possible differences in the retinal nerve fiber layer (RNFL) thickness between children with strabismus and controls. This study also compared esotropia with exotropia cases, and dominant eyes with non-dominant eyes. METHOD 31 children with esotropia, 17 children with exotropia and 32 controls were studied. The peripapillary RNFL average thickness was determined in 4 diffe...
