[Comparative assessment of the parameters of visual fixation in amblyopia of different origin].

A comparative objective study of visual fixation parameters for various types of amblyopia was performed using the NIDEK MP-1 Microperimeter. There was a positive correlation between fixation density decrease, the increase of amplitude and average displacement of the fixation point, and visual acuity decrease for all types of amblyopia. There was no significant correlation between average rate of displacement and visual acuity. The maximum disturbance of fixation parameters, including the average rate of the fixation point displacement, was registered in nystagmus.
