[Fusion consequences of a weak oculomotor deviation: clinical analysis of frequent under-evaluation].
We propose a retrospective study of symptomatic patients presenting an oculomotor deviation of small amplitude. Our population was separated in four groups depending on the type of the deviation and on the retinal correspondence. The first three groups had a normal retinal correspondence (NRC) and a torsional (group 1: N = 3), vertical (group II: N = 6) or horizontal (group III: N = 7) deviation. In group I there was no measurable subjective torsion and the verticality was inferior to 5PD and controlled by fusion in primary position. In group II and III, the maximal deviation was 5 PD and 8 PD respectively. The group IV (N = 7) was composed by patients with abnormal retinal correspondence (ARC) and small amount of horizontal deviation (< or = 15 PD). In the groups with NRC, the use of simple clinical tests (prism's bar for vertical and horizontal deviations, fundus photographs and Weiss coordimeter for torsionnal deviations) could analyze the corresponding fusional amplitude. The complaints were successfully treated by simple means in all cases. With surgery in two cases in group I, with a pure optical treatment in one case of group II and one case of group III. All others received small power prisms. We do insist on the simplicity and the efficacy of our diagnostic and therapeutic means to help patients suffering from long term underevaluated symptomatology.
