Clinical Peculiarities of Different Types of Accommodative Esotropia

    Objective. The study of disorders of visual functions, ACPS in children with the most common types of AE.

    Materials and methods. A complex ophthalmological examination (visometry, binokulometry, refractometry, accommodometry, strabometry, the study of convergence, pupillography) in 88 patients aged 6 to 18 years with refractive AE (45 children), nonrefractive AE (31 patients) and the combinated AE (12 patients).

    Results. Besides the already known differences in the state of refraction and the value of index AC/A, the above-mentioned types of AE differ from each other in such functions as visual acuity, fusion power, binocular vision, convergence. Using pupillography it was found that in patients with any kind of AE both eyes' pupils were narrowed in comparison with healthy children, its reaction to light was weakened considerably. The latent periods of the pupillary light reflex and the pupillary near reflex were increased more then three times as in healthy children. The latent periods of pupillary dilatation after light stimulation and after convergence’s weakening were increased also. We believe that such disturbances of pupillary reactions indicate on reduction of the lability, increase ACPS's passivity that indicate on functional changes in brainstem structures of patients with AE.

    Key words: accommodation-convergence-papillary system (ACPS) pupillography, strabismus, esotropia, accommodative esotropia (AE).
