A new method of stereo-amblyopia treatment on the basis of a binocular retinal photostimulation with patterns of spatial-depth orientation
V A Kolomiets, Y O Hernaha
We studied the influence of binocular retinal photostimulation of appropriate fields with patterns of spatial-depth orientation to restore binocular and depth vision in patients with refractive amblyopia (RA) and strabismic amblyopia (SA). The treatment effect is related to photostimulation of binocular neurons in the visual cortex by stereopatterns, and to improvement of metabolic processes and blood circulation in cortical centres. The method was applied to 62 patients (aged 4 - 17 years). Visual acuity, binocular vision and depth perception were examined. The photostimulation was performed at sinoptophor. The power of the polychromatic light pulse was 2 mJ cm-2. The size of the stimulated patterns was 10 deg. Daily treatment consisted of five procedures at 5 min intervals. The course of treatment lasted 10 days. In RA group of patients, the number of subjects who had satisfactory depth vision was increased by 35.2% after treatment. The ability of depth perception was restored in 75% patients who had no depth vision. In SA group of patients, binocular vision was absent before the treatment, but after the treatment binocular vision was restored in 28%. In 50% of these patients, the ability of depth perception was also restored.
