Simple binocular vision examination on synoptophore determination of normative database of healthy adult subjects examination of binocular vision on synoptophore.

The main goal of our study was to determine the database of parameters of simple binocular vision (SBV) in healthy adult population. Next goal was to verify current data of particular parameters of SBV Average subjective deviation for far of all 74 subjects was 2.78 +/- 3.65 cm/m, of women was 2.90 +/- 3.69 cm/m and only for men was 2.00 +/- 3.49 cm/m. According our measurements the positive fusion range of all subjects is 25.10 +/- 12.77 cm/m, negative fusion range -6.45 +/- 4.18 cm/m, accommodation convergence to accommodation ratio (AC/A) is 3.41 +/- 1.47 cm/m and subjective deviation with accommodation on 33 cm (with minus 3 D) is 13.02 +/- 5.23 cm/m. Further we proved statistically significant correlation between these parameters of SBV: Age and AC/A, SU-3 and AC/A, SU0 and SU-3, SU-3 and FS0 and FS-3. Knowledge of basic SBV parameters is important not only for ophthalmologist but also for optometrists.
