The vertical horopter is not adaptable, but it may be adaptive.

Depth estimates from disparity are most precise when the visual input stimulates corresponding retinal points or points close to them. Corresponding points have uncrossed disparities in the upper visual field and crossed disparities in the lower visual field. Due to these disparities, the vertical part of the horopter--the positions in space that stimulate corresponding points--is pitched top-b...
