Retinal Never Fiber Layer Thickness in Chronic Renal Failure: Analysis by Optical Coherence Tomography

چکیده
Methods: This was a prospective, analytical, cross-sectional casecontrol study. The study sample comprised 22 eyes from 11 patients and 33 eyes from 17 patients in the case and control groups respectively. RNFLT was measured with a model 3000 OCT unit (Stratus OCT-3TM, Carl Zeiss Meditec Inc., Dublin, CA). The fast RNFL protocol was used, which consists of three consecutive 3.4 mm-diameter circular scans centered on the optic nerve. Measured parameters included overall mean RNFL and mean RNFL at the temporal (31645°), superior (46-135°), nasal (136-225°), and inferior (226-315°) quadrants. The Mann-Whitney U was employed to assess possible betweengroup differences in mean overall RNFL and RNFL at the superior, temporal, nasal, and inferior quadrants. The null hypothesis was rejected when p-values were smaller than the set significance level of <0.05.

The Retinal Nerve Fiber Layer Thickness is Related to Severity of Parkinson’s Disease
Introduction: We investigated correlation between the retinal nerve fiber layer (RNFL) thickness and the severity of Parkinson's disease (PD). Methods: In this study, the RNFL thickness of 23 patients with Parkinson’s disease (PD) was compared to normal controls (NCs). PD severity was assessed by the MDS-UPDRS (movement disorder society Unified Parkinson Disea...
متن کاملClinical Applications of Optical Coherence Tomography in Ophthalmology
Assessment of the peripapillary nerve fiber layer and macular thickness can be determined in ophthalmology using optical coherence tomography (OCT). Decreased nerve fiber layer thickness and macular ganglion cell thickness in optic nerve ischemia have been correlated with visual field loss. OCT allows deep optic nerve head evaluation which helps understand pathophysiology of diseases. Furtherm...

INTRODUCTION Optical coherence tomography is a technology that allows obtaining high resolution images of tissues in vivo, enabling the measurement of ocular structures, including the retinal nerve fiber layer and macular thickness. As a noninvasive test it's particularly useful in children, but its applicability is limited by the existence of normative values for adults only. PURPOSE To esta...

Introduction: Alzheimer disease (AD) is the most common form of dementia worldwide. The modalities to diagnose AD are generally expensive and limited. Both the central nervous system (CNS) and the retina are derived from the cranial neural crest; therefore, changes in retinal layers may reflect changes in the CNS tissue. Optical coherence tomography (OCT) machine can show delicate retinal layer...
