title: [Specific cases of normo-sensorial strabismus: accommodative microstrabismus].
abstract: This study shows that, in a population of microstrabic patients (N = 76), a regain of a normal stereoscopy was possible in 19.6 of the cases (14 cases). Of these patients, 14 were hyperopic. With the full hyperopic correction, the angle of deviation on the alternate cover test was 0.45 PD (range: 0 to 3 PD). Without correction the deviation increased to between 3 PD and 10 PD (mean: 6.3 PD). Ten patients presented an anisometropia between 0.75 D to 2.50 D. (mean: 1.4 D). All anisometropic patients were hyperopic and hyperopia was higher in the dominated eye in all these cases. These results demonstrate the interest of the definition of microtropia as a specific strabismological entity, which can be congenital or acquired and be influenced by accommodative factors. The incidence of anisometropia, as a consequence rather than a cause of the pathological dominance is discussed.
