The Riester ri-vision with Slit Retinscope is a kit of the ri-scope retinoscope with silt lamp and the riester ophthalmoscope L2. Included with this kit are two fixation cards for dynamic retinoscopy and two spare lamps. The battery handle is a Type C with rheostat for 2 Li batteries and uses the XL 3.5 V lamp.
The ri-scope retinoscope (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.
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. Countermovement (minus lines): The patient is nearsighted.
All ri-scope L ophthalmoscopes with modular design impress with their high-performance optics with aspherical condenser lens with reduced-reflection view even with small pupils and through improved ergonomics. The ri-scope L2 is the enhanced basic model with separately engageable red-free, blue and polarization filters for each aperture.
