Hypertropia
A hypertropia is a form of vertical strabismus where one eye is deviated upwards in comparison to the fellow eye. The term of hypertropia is relative to the fellow eye which, by analogy is the hypotrpoic eye- meaning that is deviated downwards. Depending on which eye is fixing, a hypertropia of one eye is the same entity as a hypotropia of the fellow eye, according to Hering’s law. By convention, the designation of the vertical strabismus is made according to the hypertropic eye.
