Second Harmonic Generation – A Novel Approach in Retinal Imaging
… label-free imaging of microtubules (MTs) in the retinal nerve fiber layer (RNFL). MTs are an important part of axonal cytoskeleton, providing structural support and serving as a railroad in intracellular transport. We demonstrate the application of SHG microscopy to the following studies: 1) Can …

DEEP LEARNING ALGORITHMS FOR OPTICAL COHERENCE TOMOGRAPHY IMAGES WITH APPLICATIONS IN GLAUCOMA
… in complex 3D biomechanical changes of the optic nerve head tissues (ONH), is indeed a well-known risk factor and considered as the only clinically treatable one. Since the inception of optical coherence tomography (OCT) technology, it has been possible for the in vivo assessment of these …

Retinal mophology and intelligence
… To investigate the relationship between retinal morphometric measures and intellectual abilities among adults with overweight and obesity. Methods: Adults between 25-45 years (N=55, 38 females) with overweight or obesity (BMI ≥25.0 kg/m2) underwent an optical coherence tomography (OCT) …

Is the Adams D-15 colour vision test a sensitive screening tool for ethambutol- and linezolid-induced optic neuropathy? A retrospective case series
… D15 (FM D15) and Adams D15 colour vision tests, retinal nerve fiber layer optical coherence tomography (RNFL-OCT) and a Humphrey visual field 24-2 (HVF 24-2). According to the results of these tests, the patients were classified into 3 groups: “No toxicity”, “Uncertain toxicity” or “Confirmed …

Evaluation of Ocular Pulse Amplitude-related Parameters measured by Dynamic Contour Tonometry and Ocular Blood Flow Analyzer
… deviation (MD) of visual field (VF) tests and retinal nerve fiber layer (RNFL) thickness of Stratus optical coherence tomography (OCT) in medically treated NTG patients. Both IOP and OPA of NTG patients were lower than those of normal subjects whereas PA, PV and POBF was not significantly …

INTERRELATIONSHIPS BETWEEN MACULAR CAROTENOIDS, RETINAL MORPHOMETRY, AND COGNITIVE FUNCTION IN PERSONS WITH MULTIPLE SCLEROSIS
… antioxidant effects of carotenoids could support nerve health and protect against cognitive decline. However, macular xanthophyll status and its implications for markers of neuroaxonal degeneration, such as retinal morphometry, have not been examined among persons with MS. Specifically, the …

On Wavelet-Based Methods for Scalar-on-Function Regression
… develop predictive models based on measures of retinal nerve fiber layer (RNFL) thickness. The estimates are obtained via an elastic net penalized fitting procedure. The second and third approaches consist of using novel measures of RNFL characteristics to discriminate between healthy and …

Optical coherence tomography for retinal diagnostics
… optical coherence tomography (PS-OCT) for retinal nerve fiber layer (RNFL) birefringence measurement and dual-wavelength photothermal optical coherence tomography (DWP-OCT) for microvasculature blood oxygen saturation (SO2) measurement. In the study, a single-mode-fiber based …

Lamina Cribrosa and Optic Nerve Head Geometry as a Function of Myopia in Older Normal Eyes
… of glaucoma. However, their impact on optic nerve head (ONH) structure in normal eyes has not been fully described. We examined whether differences exist in ONH and lamina cribrosa structure with myopia in older normal eyes. Methods: Spectral domain optical coherence tomography (SDOCT) scans …

Longitudinal Evaluation of Retinal Capillaries in Experimental Glaucoma
… (RPCs) has been hypothesized to play a role in retinal ganglion cell axon degeneration in glaucoma. Previous histological work has shown that structural alterations and losses of RPCs are associated with glaucomatous pathology. However, the lack of longitudinal in vivo data characterizing RPC …

Aquaporin 4 and Kir4.1 Distribution in Retinal Glial Cells of Normal Macaque Eyes and Eyes with Experimental Glaucoma
… buffer. Retina samples were taken from several nerve fiber rich regions within 5 mm of the optic nerve head (ONH) in the vicinity of the standard optical coherence tomography (OCT) peripapillary scan. Samples were cut at a thickness of 40 µm on a vibratome and were subjected to antigen retrieval …

Evaluating The Estimation of Neuronal Loss in Glaucoma
… OCT (SD OCT), cross-sectional images of the retinal nerve fiber layer (RNFL), optic nerve head (ONH) and the macula can be acquired at high resolutions and quantified with excellent repeatability and reproducibility. While OCT morphological measures are clinically used as to represent retinal …

Biomarcatori diagnostici e prognostici nella Sclerosi Multipla: un approccio multidimensionale
La presente Tesi si prefigge lo scopo di valutare l'accuratezza diagnostica e l'utilità clinica di diversi biomarcatori nell'ambito della Sclerosi Multipla (SM), al fine di una possibile implementazione di questi ultimi nella pratica clinica. In ambito diagnostico, il κ index, calcolato come …
