Abstract
Aim: To establish the mean value for the field of binocular single vision (BSV) on the Goldmann perimeter in a visually normal population.
Methods: This was a prospective study on u visually normal, asymptomatic population. One hundred and nineteen participants completed the study. The field of BSV was evaluated using the III4e target on the Goldmann perimeter, and scored using the Sullivan template. Subgroup analysis was performed according to age to assess for age-related changes to the score.
Results: A score of 100% was rarely recorded for the participants. The overall population mean score was 04.43% (SD 4.25%; median 94.00%). One-way ANOVA test revealed a statistically significant reduction in the field of BSV with increasing age (p=0.0000). Correlation testing was performed (Pearson rank correlation r=-0.44).
Conclusion: Age-related normal scores were produced and show strong evidence of a reduction in the field of BSV with increasing age.
