Riester ri-scope Retinoscope
The ri-scope® retinoscope (skiascope) measures
the refractive power of the eye. Errors of refraction,
such as in short and long-sightedness, as well as
astigmatism can be recognized and determined.
Choice of XL 3.5 V xenon lamp or HL 2.5 V
halogen lamp.
Two models are available:
-The spot-light retinoscope projects a circular light
beam.
-The slit-light retinoscope with a light beam in the
form of a line, simplifies recognition and the
determination of astigmatic refractive errors. The
reflex in the form of a line is moved vertically to
the axis across the pupils of the patient with a slight
oscillating movement. The shadow moves in the
same or opposite direction.
Co-movement (plus lines): The patient is longsighted.
Counter-movement (minus lines): The patient is
short-sighted.
Simple operation with knurled thumb screw. The
line and spot image can be focused with the
operating element and turned 360º, angle can be
read off the integrated scale.
Holder for hanging and fixing the fixation card into
position for dynamic retinoscopy.
Two fixation cards supplied. The patient’s eye can
adjust optimally to the distance to the retinoscope.
Integrated eyeglass protection.
Bayonet fitting for fast and secure attachment to the
handle.
Dust-tight, very sturdy and light casing made of
impact resistant plastic.
Simple exchange of the lamp at the base of the
instrument head
