Does anybody know if the AO Stereopsis Test at 6 meters (4 line version) and the AO Suppresion Test at 6 meters are still being used or if there are any other tests that can be used in their place? I went to a civilian optometrist and he says he's never heard of these tests. Any info would be appreciated.

Failure of the Vision Test Apparatus (VTA-DP) or its newer replacement, the Optec Vision Tester (OVT), screening depth perception test with uncorrected refractive errors should be retested with refraction correction in place, regardless of level of unaided visual acuity. Failure even with correction is disqualifying, but may be considered for waiver consideration by higher waiver authorities, only after completion of a full evaluation by an ophthalmologist or optometrist, to include all of the following: ductions, versions, cover test and alternate cover test in primary and 6 cardinal positions of gaze, AO Vectograph Stereopsis Test at 6 meters (4 line version), AO Suppression Test at 6 meters, Randot or Titmus Stereopsis Test, Red Lens Test, and 4 Diopter Base out Prism Test at 6 meters. These tests are designed to identify and characterize motility/alignment disorders, especially microtropias and monofixation syndrome. The results of these tests done
locally are considered to be preliminary, but will be used by waiver authorities to determine whether a candidate should be permanently disqualified without any waiver consideration, to identify if there are potentially correctable causes, and to determine whether further evaluation is required.

So: (VTA-DP) or its newer replacement, the Optec Vision Tester (OVT), is what is normally used.
