[Correction of presbyopia in users of video terminals by progressive half-spectacles].

Twenty one presbyopes of 48 years old and over (considered as emmetropes or light ametropes), and a young aphakik patient wearing contact lenses, working before visualization screens, were equipped with semi-framed Varilux 2. The correction of their Intermediary Vision was made precisely on the upper edged level of the frame; the correction of their Near Vision was made by an addition of strength reduced by half when compared to the usual graduation. This specific equipment was compared to the classical system of their choice, manufactured at the same time and offering the same strength in Near Vision.

[Multifocal vitelliform dystrophy : a case report (author's transl)].

A case of multiple vitelliform dystrophy is described in an adult white woman ; vision, angiography, EOG are the same as in true Best's disease, but the reduction of vision seams more severe and occurs earlier. The extramacular discs are smaller, faster in evolution, they can appear, disappear or coalesce as in our case. The disease is genetically much less demonstrative than central vitelliform dystrophy.
