Abstract

The purpose of this study was to assess the binocular fusion values under free haploscopy in non-strabismus patients. One hundred seventy people (the age was from 20 to 60 years; objective refraction range 6.0D to +6.0D) were examined. The measurement of the binocular fusion under free haploscopy was performed in patients with physiological diplopia. To investigate the fusion and calculate the area of binocular interaction (ABI), we used the binarimeter, a diploptic device. The normative database of ABI in non-strabismus patients was presented. The mean area of ABI in emmetropic patients was 266.08 ± 99.53 cm2, in myopic patients -164.90 ± 118.60 cm2 (p < 0.001) and in hypermetropic patients -160.46 ± 126.47 cm2 (p < 0.001). The ABI was significantly correlated with accommodation amplitude, refraction value and age. We concluded that the ABI is an individual parameter and may be an indicator of neuroplasticity.
