[Differential diagnostic criteria of accommodative disorders]

A total of 150 patients (300 eyes) aged from 6 to 23 with myopia of different degrees were assessed to define differential diagnostic criteria of accommodative disorders such as accommodative insufficiency, habitual excess, and spasm. The patients were divided into 4 groups. Group 1 included 88 patients (175 eyes) with myopia from -0.75 to -8.5 diopters (general group), group 2-23 patients (46 eyes) with accommodative insufficiency, group 3-20 patients (39 eyes) with habitual accommodative excess, and group 4-20 patients (40 eyes) with accommodative spasm. In all cases subjective and objective parameters of accommodation were fully assessed and differential diagnostic criteria identified.
