Radiant Energy and the Eye

Ophthalmology Series. (Pp 321, Figs 167, Tables 41. £25.00). London: Bailliere Tindall, 1980. THIS well presented and well organised book discusses the known and potential effects and hazards of radiant energy on the eye. It admirably correlates current scientific knowledge concerning radiant erergy with its biological effects on ocular structures and documents the various mechanisms whereby v;...

Radiant energy required for infrared neural stimulation

Infrared neural stimulation (INS) has been proposed as an alternative method to electrical stimulation because of its spatial selective stimulation. Independent of the mechanism for INS, to translate the method into a device it is important to determine the energy for stimulation required at the target structure. Custom-designed, flat and angle polished fibers, were used to deliver the photons....

Measurement of Radiant Energy in Light Therapy

Cataract after exposure to non-ionizing radiant energy.

The case histories of two individuals exposed to thermal radiation emitted from an electric oven and range were presented. In one patient, earlier exposure to medical diathermy appears to have initiated delayed or late-appearing, capsular cataracts. Instead of the anticipated slow progression, the cataractogenesis was accelerated following recent, repeated exposure to the intense, infrared radi...

Effect of radiant energy on near-surface water.

While recent research on interfacial water has focused mainly on the few interfacial layers adjacent to the solid boundary, century-old studies have extensively shown that macroscopic domains of liquids near interfaces acquire features different from the bulk. Interest in these long-range effects has been rekindled by recent observations showing that colloidal and molecular solutes are excluded...
