The aging human lens: structure, growth, and physiological behaviour.
The aging human lens has been the subject of intense research over the past 20 years, for a number of quite disparate reasons. The fact that the incidence of cataract rises exponentially with age after 50 years provides the driving influence for much of the eVort, but the unique accessibility, homogeneity, and basic simplicity of structure of the organ itself makes it a fruitful system for fund...
متن کاملThe shape of the aging human lens: curvature, equivalent refractive index and the lens paradox
Scheimpflug slit images of the crystalline lens are distorted due to the refracting properties of the cornea and because they are obliquely viewed. We measured the aspheric curvature of the lens of 102 subjects ranging in age between 16 and 65 years and applied correction for these distortions. The procedure was validated by measuring an artificial eye and pseudophakic patients with intraocular...
متن کاملPrecapsular film on the aging human lens: precursor of pseudoexfoliation?
In many older patients we observed a layer of subtle opacification on the anterior lens capsule, appearing as a ground glass film biomicroscopically. This precapsular film (PCF) could be uniform but often had radial grey lines in the mid zone, holes in the paracentral region, and was occasionally rolled up in strings. Lens capsular material obtained at cataract extraction was studied in patient...
متن کاملEffect of Mild Heating on Human Lens Epithelial Cells: A Possible Model of Lens Aging
This study aims to investigate the effect of mild heating on lens epithelial cells and to explore its possibility as an in vitro model for lens aging. Human lens epithelial cells (LECs) were heated at 50 °C for a cellular lens aging study. Analysis of the head group order of lens membranes was performed using Laurdan labeling. Immunofluorescence was performed to detect changes in α-crystallin e...
متن کاملStraylight effects with aging and lens extraction.
PURPOSE To assess possible gains and losses in straylight values among the population to consider straylight as added benefit of lens extraction. DESIGN In this cross-sectional design, data from a multicenter study on visual function in automobile drivers were analyzed. METHODS On both eyes of 2,422 subjects, visual acuity (logarithm of the minimum angle of resolution [logMAR] in steps of 0...
