PURPOSE We calculated and validated a linear discriminant function (LDF) for Fourier domain optical coherence tomography (OCT) to improve the diagnostic ability of retinal and retinal nerve fiber layer (RNFL) thickness parameters in the detection of Alzheimer's disease (AD). METHODS We enrolled AD patients (n = 151) and age-matched, healthy subjects (n =(More)
BACKGROUND To evaluate and compare the ability of two Fourier-domain optical coherence tomography (OCT) devices to detect retinal and retinal nerve fibre layer (RNFL) atrophy in patients with Alzheimer's disease (AD) compared with healthy subjects; to test the intra-session reliability of two OCT devices in AD patients and healthy subjects. METHODS AD(More)
AIMS To determine whether there is an association between retinal thinning and functional rating scales in patients with Parkinson's disease (PD). MATERIALS AND METHODS Patients with PD (n=153) and controls (n=242) underwent evaluations of the macula and retinal nerve fibre layer (RNFL) using two new-generation Fourier domain optical coherence tomography(More)
PURPOSE To demonstrate axonal loss in the retinal nerve fiber layer (RNFL) of patients with Parkinson's disease (PD) and to evaluate the ability of Fourier-domain optical coherence tomography (OCT) to detect RNFL degeneration and retinal thinning in these patients. METHODS PD patients (n=100) and healthy subjects (n=100) were included in the study and(More)
Editor, A t the present time, researchers are searching for biomarkers and tools to detect the Alzheimer’s disease (AD) in early phases, especially in high-risk families, and to monitor disease progression. Recent studies have revealed degenerative changes in optic nerve fibers, causing thinning of the retinal nerve fiber layer (RNFL) in patients with AD(More)
PURPOSE To evaluate and compare the ability of 3 protocols of Fourier-domain optical coherence tomography (OCT) to detect retinal thinning and retinal nerve fiber layer (RNFL) atrophy in patients with Parkinson's disease (PD) compared with healthy subjects. To test the intrasession reproducibility of RNFL thickness measurements in patients with PD and(More)
PURPOSE To quantify changes in the retinal nerve fiber layer (RNFL) of patients with multiple sclerosis (MS) over 3 years and to evaluate whether treatment protects against RNFL degeneration. METHODS Ninety-four MS patients and 50 healthy subjects were followed-up over 3 years. All subjects underwent a complete ophthalmic examination, which included(More)
BACKGROUNDS/AIMS To evaluate the effect of uncomplicated cataract phacoemulsification on the measurements of macular and retinal nerve fibre layer (RNFL) in healthy subjects using two spectral domain (SD) optical coherence tomography (OCT) instruments--Cirrus OCT (Zeiss) and Spectralis OCT (Heidelberg)--and to assess the reliability of the measurements(More)
PURPOSE To evaluate the effect of uncomplicated cataract phacoemulsification on macular and retinal nerve fiber layer (RNFL) thickness using two spectral-domain optical coherence tomography (OCT) instruments, Cirrus OCT and Spectralis OCT, in patients having non-insulin-dependent diabetes mellitus (NIDDM) without retinopathy, and to assess the reliability(More)
