A laser retinoscope.

A retinoscope that uses a He-Ne laser as its light source has been designed. By this means it is possible to improve the performance of the conventional retinoscope. In particular the contrast of the fundus reflex has been enhanced and the retinoscope can be used at a greater working distance than usual. By using a polarized laser the specular reflections from the eye are completely suppressed. The retinoscope lends itself to refractions under normal room illumination. Patients find the light from the laser retinoscope less bothersome than that of the usual tungsten filament lamp. Advantages and disadvantages of the unit are discussed.
