Objective: To assess and compare sensory-motor status and clinical features of type I and type II acute acquired concomitant esotropia (group A) and decompensated monofixation syndrome (group B).
Methods: In a retrospective, comparative study, 26 patients with a confirmed postoperative diagnosis of type I and II acute acquired concomitant esotropia and monofixation syndrome were enrolled. The 2-tailed unpaired t test and 2-tailed chi(2) test were performed to compare angle of deviation and sensory-motor status under the environmental conditions and after prismatic adaptation test and progressive prism test of 2 groups.
Results: All of the patients of group A and 4 patients (33%) of group B experienced diplopia under viewing conditions in the Worth's 4 dot and Bagolini striated glass tests. The TNO stereo test showed the total absence of stereopsis in 6 patients in group B and a significantly lower stereoacuity in group A in the remaining 6 patients (p < 0.0001). The prismatic adaptation test was positive in all of the patients in group B and in 10 patients (71%) in group A (p = 0.39). The value of the angle of deviation after the progressive prism test was significantly higher in group B than in group A (p = 0.02). At the end of the progressive prism test, all of the patients in group A and only 2 patients in group B were orthotropic (p = 0.01).
Conclusions: Bagolini striated glass and Worth's 4 dot tests under viewing conditions and responses under prisms allow for the differentiation of the 2 forms and lead to an accurate aesthetic and functional prognosis.
