Sensory Testing in Exodeviations
Carol F. Dickey, C.O.
Sensory and motor fusion are integrated functions of binocularity and cannot be separated. Therefore, in order to successfully plan a course of management it is necessary to evaluate and understand the relationship between the malposition of the eyes and the resulting sensory outcome.
The progression of suppression is the catalyst for the deterioration of alignment. Assessing the sensory status through subjective and objective testing is advocated and the benefits and limitations are relayed. The remainder of the paper discusses the different phases of exodeviations - exophoria, intermittent exotropia and exotropia. In conclusion, the author encourages understanding exodeviations as a continuum consistent with the progression of suppression. It is suggested that examiners follow changes both subjectively and objectively in the attempt to preserve fusion.
