ABSTRACT

Background: A particular feature of dissociated strabismus is that the frequency of presentation and its magnitude is variable. It is common to find that in certain examinations is very obvious, and in others not so much. To facilitate exploration some maneuvers are described: Bielchowsky’s maneuver, Bielchowsky’s phenomenon and Posner test.
Objective: to compare the presence and magnitude of the ocular movement in dissociated strabismusin Posner’s Test using opaque versus translucent occluders.
Methods: Prospective, transversal, descriptive study. Patients with diagnosis of were included. Posner's test in two ways: 1) With opaque occluders, and 2) with translucent occluders was perforned.
Results: Ninety five percent of the patients presented horizontal deviation. Posner´s Test with opaque occluderwas positive in all cases (100%). Posner´s test with translucent occluderswas positive in 94% of the patients (p= 8). The magnitude of the ocular movement was significantly smaller using translucent occludersthan opaque occluders. (p= 0.0001).
Conclusions: The Posner´s test using opaque occluderswas more efective to demonstrate clearly and precisely the size of the ocular movement in dissociated strabismus.
