Age-related compaction of lens fibers affects the structure and optical properties of rabbit lenses
BACKGROUND The goal of this investigation was to correlate particular age-related structural changes (compaction) to the amount of scatter in rabbit lenses and to determine if significant fiber compaction occurred in the nuclear and inner cortical regions. METHODS New Zealand White rabbits at 16-20 months old (adult; n = 10) and at 3.5-4 years old (aged; n = 10) were utilized for this study. ...
متن کاملAge-related lipid oxidation in human lenses.
PURPOSE To quantify age-related changes in products of lipid oxidation in human lenses and to relate these changes to membrane hydrocarbon chain structure. Deviation from a well-defined membrane-lipid composition and structure could result in alterations in membrane function and disruption of the homeostasis of the cell. METHODS Infrared spectroscopy was used to detect lipid compositional and...
متن کاملAccommodative intraocular lenses for age-related cataracts.
The standard intraocular lens (IOL) that is used to replace a cataractous lens cannot change focus from distant to near objects, so most patients need glasses for near vision after cataract surgery. Limited evidence suggests that accommodative IOLs provide better near vision than monofocal IOLs, but not better than multifocal IOLs. Long-term follow-up is needed to confirm patient outcomes, and ...
متن کاملExecutive function in daily life: Age-related influences of executive processes on instrumental activities of daily living.
The present study of older adults used structural equation modeling (SEM) to examine the relationships between 3 executive processes underlying executive function (EF) (inhibition, task switching, updating in working memory), and 2 types of instrumental activities of daily living (IADLs) (self-report, performance based). Experimental tasks of executive attention and self-report or performance-b...
