[The 30 prism test].

Abstract

The 30-prism-test is a relatively quick and simple method for many-sided testing binocular behaviour in near distance in patients with reading difficulties and asthenopic symptoms, respecting well known and assumed causes of the disturbances. Therefore indications for treatment are given.

Occupational health hazards to the ultrasonographer and their possible prevention.

Occupational health hazards in ultrasonography are becoming more prevalent as the field continues to grow. Eye strain, musculoskeletal pain or injury, carpal tunnel syndrome, repetitive strain injuries, stress, burnout, and other hazards have been addressed as concerns in other studies and surveys. These topics are discussed, as well as the possible preventive measures that may be used to maximize and maintain the ultrasonographer's well-being throughout his or her career.

Reinvention of visual fatigue: accumulation of scientific knowledge or neglect of scientific history?

The development of science is believed to be a continuous accumulation of knowledge, giving rise to the somewhat false idea that the most recent knowledge is the most valid and most appropriate. Neglect of the history of a scientific discipline might therefore lead to reinvention of theories that have already been proposed and experimentally investigated. In the case of visual fatigue the pioneering works of Lucien Howe, Walter Lancaster and others at the beginning of this century are very similar to contemporary work in terms of conceptual definitions, methodological approach, assessment and results. The temporal and dynamic aspects of accommodation and vergence considered important today were intensely studied and discussed by Howe and others.
