Pupillary reflex disorders in strabismic amblyopia with concomitant alternating squint

Abstract

Purpose. To study pupillary reflexes (pupillary cycle time and pupillary reaction — V) in patients with strabismic amblyopia and concomitant alternating strabismus. Material and methods. 58 children (116 eyes) with concomitant alternating strabismus and strabismic amblyopia and 10 healthy children (20 eyes) with emmetropia (the control group) were examined, along with general testing, for pupillary reflexes according to S. Miller and H. Thompson’s method before and after color pulse stimulation, Sidorenko’s vacuum spectacles, and Focus and Relax programs. Results. All children with hyperopic astigmatism and high hyperopia showed a significant (p < 0.001) decrease in pupillary cycle time after treatment, on average, from 1317,0 ± 0.6 to 900,00 ± 2.08 m/s and an increase in the pupillary reaction rate, on average, from 1.7 ± 0.17 to 2.8 ± 0.1 mm/s. Сhildren with severe amblyopia showed more pronounced pupillary reflex disorders: pupillary cycle time was 1450,0 ± 1.0 m/s and V = 1.3 ± 0.17mm/s before treatment, whilst after treatment, significant improvements were achieved:pupillary cycle time fell to 1000,0 ± 1.3 mm/s, while V grew to 2.20 ± 0.15 mm/s (p < 0.01). Conclusion. The revealed disorders of pupillary reflexes in children with strabismic amblyopia indicate the pathology of the muscle part of the pupil-accommodative system and require specific treatment.
