[Changes in visual evoked potentials curve parameters in children with amblyopia].
OBJECTIVE
The aim of the study was to correlate visual evoked potential (VEP) parameters (amplitude and latency) with visual acuity of the amblyopic eye.


METHODS
The study included 30 children aged 4.5-6 years, tested for visual acuity before refractive correction, with correction, and after pleoptic therapy. In addition, VEP parameters were recorded according to changes in visual acuity.


RESULTS
VEP curves were found to change with visual acuity of the amblyopic eye. A statistically significant correlation was obtained between amplitude values and visual acuity as well as between latency values and visual acuity (P<0.001 both).


CONCLUSIONS
Some authors have reported differences in VEP curve parameters according to visual acuity. We performed VEP assessment in children with anisometropic amblyopia and found statistically significant differences among the values obtained before refractive correction, with refractive correction and after pleoptic treatment of amblyopic eye. VEP curve values changed with improvement in visual acuity: the P100 wave amplitude was higher and latency shorter.


CONCLUSIONS
VEP may be a valid method to determine amblyopia.
