The TNO random dot stereotest (short: TNO stereo test or TNO test) is similar to the randot stereotest but is an anaglyph in place of a vectograph; that is, the patient wears red-green glasses (in place of the polarizing glasses used in the randot stereotest). Like other random dot stereotests, the TNO test offers no monocular clues.

The Worth Four Light Test, also known as the Worth's four dot test or W4LT, is a clinical test mainly used for assessing a patient's degree of binocular vision and binocular single vision. Binocular vision involves an image being projected by each eye simultaneously into an area in space and being fused into a single image.
Detached objects are one of four distinct dynamical classes of TNO; the other three classes are classical Kuiper-belt objects, resonant objects, and scattered-disc objects (SDO). [20] Sednoids also belong to detached objects. Detached objects generally have a perihelion distance greater than 40 AU, deterring strong interactions with Neptune ...
Coarse stereopsis is important for orientation in space while moving, for example when descending a flight of stairs. Fine stereopsis is mainly based on static differences. It allows the individual to determine the depth of objects in the central visual area (Panum's fusional area) and is therefore also called quantitative stereopsis.
Among the resulting 36 subjects aged 6–30 years, many had regained binocular vision (56% according to an evaluation with Bagolini striated glasses, 39% with Titmus test, 33% with Worth 4-dot test, and 22% with Random dot E test) and 57% had stereoacuity of 200 sec of arc of better, leading to the conclusion that some degrees of stereopsis can ...
It took more than 60 years to discover a second TNO, Albion (provisionally known as 1992 QB 1), in 1992. The largest known trans-Neptunian objects are Pluto and Eris , followed by Haumea , Makemake , Gonggong , Quaoar , Sedna , and Orcus , all of them being officially recognized as dwarf planets by the IAU except for Gonggong, Sedna, and Orcus.
