PURPOSE To determine whether Hartmann-Shack wavefront sensing detects differences in optical performance in vivo between poly(methyl methacrylate) (PMMA) and foldable acrylic intraocular lenses (IOLs) and between clear corneal and scleral tunnel incisions and whether optical differences are manifested as differences in visual performance. SETTING… (More)
BACKGROUND Optic neuritis is a frequent manifestation of multiple sclerosis. Visual deficits range from a minor impairment of visual functions through to complete loss of vision. Although many patients recover almost completely, roughly 35% of patients remain visually impaired for years, and therapeutic options for those patients hardly exist. Vision… (More)

A total of 21,040 electroencephalograms obtained from 6,834 children constituting the routine patient stock of an electroencephalographic department of a pediatric clinic were checked for "frequency instability". It was possible to observe an age dependence of this characteristic and determine statistical correlations with certain clinical disease units… (More)
Subjective differences in EEG evaluation are demonstrated by means of a seven step scale for grading the unspecific hyperventilation effect in 3263 EEG of children. Intermediate steps of this scale allow to minimize such unavoidable differences.
