The ri-scope® retinoscope, also referred to as the skiascope, measures the refractive power of the eye. Refractive flaws, such as near- and far-sightedness, as well as astigmatism can be detected and diagnosed. Riester offers to model: the split-light retinoscope (glow is a stitch).

Features and benefits
Available with XL 3.5 V xenon lamp or HL 2.5 V halogen lamp
- The slit-light retinoscope with a light beam in the form of a line, simplifies detection and diagnosis of astigmatic refractive flaws. 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. A shadow moves in the same or opposite direction.
Co-movement (plus lines): The patient is far-sighted.
Counter-movement (minus lines): The patient is near-sighted.
Easy to operate with knurled thumb screw. The line and spot image can be focussed with the controls and turned 360°, angle read-out displayed on the integrated scale.
Holder for hanging and placement of the fixation card into position for dynamic retinoscopy.
Delivered with two fixation cards. The patient’s eye can adjust optimally to the distance to the retinoscope.
