Cumulative Curve to Detect Neuroretinal Rim Area Defects in Glaucomatous Optic Nerve Heads
The aim of the study was to evaluate the capacity of rim area/disc area (RA/DA) cumulative curve analysis to distinguish optic nerve heads (ONHs) with a glaucomatous visual field from those with a normal visual field. One hundred and fifty-four subjects were consecutively recruited for the study. All the ONHs were analyzed by Image-net X Rev.3/51b (Topcon, The Netherlands), and all subjects wer...
متن کاملRetinal nerve fiber layer defect in a patient with healthy neuroretinal rim.
Ophthalmoscopic scrutiny of the nerve fiber layer was first advocated by Hoyt, over 30 years ago. In the following years, the importance of localized defects of the retinal nerve fiber layer (NFL) for the diagnosis of glaucoma has been demonstrated in many studies. The evaluation of the NFL, though relatively difficult and subjective, has become routine in the common ophthalmic examination. We ...
متن کاملRetinal blood flow measurements and neuroretinal rim damage in glaucoma.
AIM To assess retinal blood flow characteristics in subjects with normal tension glaucoma (NTG), primary open angle glaucoma (POAG), and a group of controls using the Heidelberg retina flowmeter (HRF). The vascular parameters were correlated against structural damage of the optic nerve head, assessed using the Heidelberg retina tomograph (HRT). METHODS HRF images were obtained in 76 subjects ...
متن کاملComparing Optic Nerve Head Rim Width, Rim Area, and Peripapillary Retinal Nerve Fiber Layer Thickness to Axon Count in Experimental Glaucoma
PURPOSE We compare spectral-domain optical coherence tomography (SDOCT) measurements of minimum rim width (MRW), minimum rim area (MRA), and peripapillary retinal nerve fiber layer thickness (RNFLT) to complete orbital optic nerve axon counts in nonhuman primates (NHP) with unilateral experimental glaucoma (EG). METHODS Biweekly SDOCT measurements of MRW, MRA, and RNFLT were acquired under ma...
متن کاملPeptidergic innervation of the retinal vasculature and optic nerve head.
Using immunocytochemistry, the authors studied the peptidergic innervation to the vasculature of the optic nerve and retina in the rhesus monkey and rat. In the monkey, beaded nerve fibers immunoreactive to the vasoactive peptides, calcitonin gene-related peptide (CGRP), neuropeptide Y (NPY), substance P (SP), and vasoactive intestinal peptide (VIP), are present in the adventitia and perivascul...
