Slide Series D
Stereoscopic Vision Slides (Yellow Binding)
A gross qualitative stereopsis assessment can be obtained using two images of the same object, hypothetically taken from slightly different angles, to indicate depth perception.
The slides are inserted into the slide holders with the controls of each slide positioned toward or away from the subject.
The patient is then required to descrbe the apparent effect (i.e. a swing moving towards or away from them).
The test should be repeated, with the slide controls changing position, to ensure the stereoscopic effect is aunthentic and the patient is not guessing.
