Abstract

Primary microtropia is a clinical entity defined by anomalous retinal correspondence of less than 5°. Heredity plays a role. Fixation may be central or eccentric. Anisometropia or heterophoria are additional, but not essential, findings. Microtropia helps achieve a better understanding of amblyopia and of pathogenesis of strabismus. However insignificant microtropia is from the cosmetic point of view, it may be important to factors in strabismus.
