Macular pigment and age related macular degeneration.
The present concepts of the pathogenesis of AMD include cumulative light damage by oxidative processes in the macular photoreceptors as environmental co-factor for the development of AMD. The direct causative connection of this hypothesis has still to be established but wide circumstantial evidence from epidemiological and basic scientific investigations are strongly supportive. Macular pigment...
متن کاملSubducted and melanotic cells in advanced age-related macular degeneration are derived from retinal pigment epithelium.
PURPOSE To describe, illustrate, and account for two cell types plausibly derived from RPE in geographic atrophy (GA) and choroidal neovascularization (CNV) of AMD, using melanosomes, lipofuscin, and basal laminar deposit (BLamD) as anatomical markers. METHODS Human donor eyes with GA (n = 13) or CNV (n = 39) were histologically processed, photodocumented, and analyzed for frequencies of occu...
متن کاملFluorescent pigments of the retinal pigment epithelium and age-related macular degeneration.
The major hydrophobic fluorophore of the retinal pigment epithelium (RPE) is A2E, a pyridinium bis-retinoid derived from all-trans-retinal and phosphatidyl-ethanolamine. The accumulation of fluorophores such as A2E is implicated in the pathogenesis of age-related macular degeneration (AMD), a disease associated with the deterioration of central vision and a leading cause of blindness in the eld...
متن کاملIn vivo imaging of retinal pigment epithelium cells in age related macular degeneration.
Morgan and colleagues demonstrated that the RPE cell mosaic can be resolved in the living human eye non-invasively by imaging the short-wavelength autofluorescence using an adaptive optics (AO) ophthalmoscope. This method, based on the assumption that all subjects have the same longitudinal chromatic aberration (LCA) correction, has proved difficult to use in diseased eyes, and in particular th...
متن کاملSlow progression of exudative age related macular degeneration associated with hypertrophy of the retinal pigment epithelium
RATIONALE Choroidal neovascular (CNV) lesions in younger patients are often accompanied by the appearance of a surrounding ring of pigment that is associated with disease regression or slowed disease progression. In older patients with age-related macular degeneration (AMD), however, hypertrophy of the retinal pigment epithelium (RPE) is known to occur but has not previously been reported to b...
