Vision acuity and visual evoked potentials (VEP) to a homogeneous light field and chess field reversion were studied in children aged 5-6 years with unilateral amblyopia before and after 3-month direct total occlusion of the intact eye. Occlusion of the intact eye resulted in improvement of the vision acuity and VEP of the amblyopic eye, that correlated with the degree of amblyopia. At the same time examinations of the intact eyes revealed reduced amplitude of VEP to large and increased latency to small chess pattern cells but no changes of the vision acuity. The results evidence the necessity of monitoring the occlusion by VEP recording to prevent the detrimental effects of visual deprivation on the development of the system of vision in a child.

[Computer treatment of strabismus and amblyopia using random-dot stereograms].

Application interactive CLASS software for stimulating productive binocular cooperation based on random-dot patterns and stereograms was used for treating strabismus and amblyopia in 105 children during a standard course of treatment. The children were divided into 3 groups treated by the CLASS alone (1), Class + two other application programs (2), and CLASS + traditional methods. General positive changes (improvement of visual acuity, decrease of eye deviation, etc.) were similar in these 3 groups. Positive effect of CLASS exercises on binocular visual mechanisms was significant. Due to precise evaluation of binocular interaction provided by CLASS, positive changes in binocular cooperation and stereovision were attained in 93% of children.
