The effect of pleoptic treatment on the stability of visual fixation in children and adolescents with amblyopia of various degrees
View through CrossRef
Purpose. This study assesses the effect of pleoptic treatment on the stability of visual fixation in children and adolescents with amblyopia of various degrees. Material and methods. The effect of the treatment in 35 children (35 eyes) with amblyopia of various degrees was evaluated using the MP-1 Microperimeter. The stability was determined by two criteria — number of fixation point hits in the 2° zone and the width of the field of fixation. Children underwent a standard course of treatment. Results. There was an improvement in the stability of visual fixation after treatment. The number of fixation point hits in the 2° zone increased from 44.8±4.1% to 52.6±3.8%. At the same time, the width of the field of fixation after treatment decreased from 6.5±0.7° to 5.2±0.5°. Visual acuity with correction in children with amblyopia correlates with the number of fixation point hits in the 2° zone (direct high correlation “+0.7”) and width of the field of fixation (inverse high correlation “–0.7”) both before and after the treatment. Conclusion. Stabilization of visual fixation was observed in patients with amblyopia of varying degrees after the pleoptic treatment.

Title: The effect of pleoptic treatment on the stability of visual fixation in children and adolescents with amblyopia of various degrees
Description:
Purpose.
This study assesses the effect of pleoptic treatment on the stability of visual fixation in children and adolescents with amblyopia of various degrees.
Material and methods.
The effect of the treatment in 35 children (35 eyes) with amblyopia of various degrees was evaluated using the MP-1 Microperimeter.
The stability was determined by two criteria — number of fixation point hits in the 2° zone and the width of the field of fixation.
Children underwent a standard course of treatment.
Results.
There was an improvement in the stability of visual fixation after treatment.
The number of fixation point hits in the 2° zone increased from 44.
8±4.
1% to 52.
6±3.
8%.
At the same time, the width of the field of fixation after treatment decreased from 6.
5±0.
7° to 5.
2±0.
5°.
Visual acuity with correction in children with amblyopia correlates with the number of fixation point hits in the 2° zone (direct high correlation “+0.
7”) and width of the field of fixation (inverse high correlation “–0.
7”) both before and after the treatment.
Conclusion.
Stabilization of visual fixation was observed in patients with amblyopia of varying degrees after the pleoptic treatment.
