Melanopsin retinal ganglion cell loss and circadian dysfunction in Alzheimer's disease (Review).
Alzheimer's disease affects 27 million individuals and is the most common cause of dementia worldwide. The pathology of Alzheimer's disease is primarily due to the β‑amyloid deposits and neurofibrillary tangles. These deposits exist largely in the cerebral blood vessels, but have also been shown to exist in retinal vessels. A new class of cells that were recently identified, known as melanopsin...
متن کاملRetinal Ganglion Cell Complex in Alzheimer Disease: Comparing Ganglion Cell Complex and Central Macular Thickness in Alzheimer Disease and Healthy Subjects Using Spectral Domain-Optical Coherence Tomography
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...
متن کاملMelanopsin retinal ganglion cell loss in Alzheimer disease
OBJECTIVE Melanopsin retinal ganglion cells (mRGCs) are photoreceptors driving circadian photoentrainment, and circadian dysfunction characterizes Alzheimer disease (AD). We investigated mRGCs in AD, hypothesizing that they contribute to circadian dysfunction. METHODS We assessed retinal nerve fiber layer (RNFL) thickness by optical coherence tomography (OCT) in 21 mild-moderate AD patients, ...
متن کاملEstimating the rate of retinal ganglion cell loss in glaucoma.
PURPOSE To present and evaluate a new method of estimating rates of retinal ganglion cell (RGC) loss in glaucoma by combining structural and functional measurements. DESIGN Observational cohort study. METHODS The study included 213 eyes of 213 glaucoma patients followed up for an average of 4.5 ± 0.8 years with standard automated perimetry visual fields and optical coherence tomography. A c...
متن کاملRetinal ganglion cell loss in superoxide dismutase 1 deficiency.
PURPOSE To investigate the influence of deficiency in superoxide dismutase (SOD) 1, a major antioxidative enzyme, on retinal ganglion cells (RGCs). METHODS In the SOD1 total knockout (SOD1-deficient) mice, the level of superoxide anion was measured using dihydroethidium. The number of RGCs was counted in both the retinal sections and the flat-mount retinas after retrograde labeling. Thickness...
