[Visual evoked potentials in infants in health and hypoplasia of the optic nerve].

Visual evoked potentials (VEP) in response to chess field reversion were studied in 29 infants aged from 6 weeks to 1.5 years with optic nerve hypoplasia and in healthy age-matched controls. Analysis of VEP in healthy children showed that the interval between weeks 6-9 and 16-20 of life was the period of their most rapid maturation, this making this period in the development of the optic system of man particularly significant.

[Visual evoked potentials in the evaluation of visual acuity in infants].

Vision acuity was assessed by visual evoked potentials (VEP) in response to low-frequency chess pattern reversion in 31 full-term healthy babies aged 6 to 28 weeks. The mean vision acuity of babies aged 6 to 9 weeks was 0.5 +/- 0.

[Electrophysiological and neuroradiological methods in the diagnosis and prognostication of functional outcome in young children with lesions of the visual tract].

The authors analyze the data of computer-aided tomography, neurosonography, and visual evoked potentials to chess pattern reversal in 14 infants aged 6 to 11 months with partial atrophy of the optic nerve and/or visual cortex involvement before and in various periods after transcutaneous electric stimulation combined with neurotrophic drug therapy. The advantages of comprehensive examinations in neuroophthalmological diagnosis in infants are shown, as is the possibility of using electrophysiological and neuroradiological methods for prediction of functional outcomes in the said patient population.

[The effect of occlusion of the better seeing eye on the function of the visual system in children with unilateral amblyopia].

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.

[Electrophysiological methods in assessing the risk for the development of multiple sclerosis in adolescents with monosymptomatic optic neuritis].

Pattern electroretinograms and visual evoked potentials (VEP) were investigated in response to reversal checker-board patterns with different sizes of checks in 13 adolescents with monosymptomatic optic neuritis in acute period and in the course of convalescence 1-2 and 12-36 months after the disease onset. All the children underwent computer tomography of the orbit and brain. The results allowed identification of high and low multiple sclerosis risk groups.
