Hering's law of visual direction describes the perceived visual direction of a point relative to an observer.
In studies of binocular vision the horopter is the locus of points in space that have the same disparity as fixation.
In ophthalmology, horror fusionis is a condition in which the eyes have an unsteady deviation, with the extraocular muscles performing spasm-like movements that continuously shift the eyes away from the position in which they would be directed to the same point in space, giving rise to diplopia.
Hypertropia is a condition of misalignment of the eyes (strabismus), whereby the visual axis of one eye is higher than the fellow fixating eye.
