Light-induced retinal damage using different light sources, protocols and rat strains reveals LED phototoxicity.
To save energy, the European directives from the Eco-design of Energy Using Products (2005/32/CE) have recommended the replacement of incandescent lamps by more economic devices such as Light Emitting Diodes (LEDs). However, the emission spectrum of these devices is enriched in blue radiations, known to be potentially dangerous to the retina. Recent studies showed that light exposure contribute...
متن کاملRetinal microscope.
An instrument is described that provides a stable magnified image for ophthalmoscopy and a low power operating microscope combined to allow greatly improved fundal inspection and to eliminate the need to change instruments during detachment surgery.
متن کاملThe Dental Operating Microscope
Endodontic therapy is performed in a naturally dark and confined working space. Operating microscopes were introduced into Endodontics in the early 1990s, and then into endodontic specialty programs in the United States. Since then, operating microscopes have become widely accepted by endodontists and are also increasingly being used by other specialists. The American Association of Endodontist...
متن کاملBlinded by the light: retinal phototoxicity in the context of safety studies.
In a seminal study published in 1966, Werner K. Noell and associates reported that the "retina of laboratory rats is affected irreversibly by intense light applied for less than an hour or for up to 2 days depending on the experimental conditions." (Noell et al., 1966). They found this effect when the retinas of "normal unanesthetized and unrestrained rats were maintained continuously for 24 ho...

a variety of configurations and magnifications. With the aid of a fiberoptic headlamp system, light can be projected in the line of sight to prevent the creation of shadows in the surgical field and render optimal visualization of the treatment site. However, the magnification of loupes is limited (2.5 to 6.0 ) and their optics are convergent, which creates eye strain and fatigue. In order to a...
