Description
The Stereo Optical SO016 Special Randot® Stereotest is a combination test that incorporates elements of the Randot and Original Stereo Fly tests in one portable clinical booklet. It allows the examiner to assess both gross stereopsis and fine stereoacuity using recognizable and random-dot targets.
The large house-fly image provides an intuitive gross-stereopsis test that is particularly useful for young children or patients who have difficulty understanding more complex instructions. When binocular stereopsis is present, the fly appears three-dimensional and elevated from the page.
For finer measurement, the booklet contains a multiple-choice series of circles on random-dot backgrounds. In each target, one of three circles appears to project forward. Ten graded levels assess stereoacuity from 400 to 20 seconds of arc at a testing distance of 16 inches. The test also incorporates suppression checks for evaluating the visual contribution of each eye. The combination of Randot and Stereo Fly components is confirmed by Stereo Optical, while its circle levels and administration are detailed in the official SO016 manual.
