| Abstract |
PURPOSE
The binocular single vision test plays an important role in evaluating severity and progression of diplopia, and a motility disorder. The purpose of this study is to determine the normal value of the field of binocular single vision according to the age and the sex of Korean. METHODS: The field of binocular single vision was examined in normal 100 Koreans using Goldmann perimeter. RESULTS: The field of binocular single vision was 55.6degrees at upward gaze, 65.7degrees at left lateral gaze, 64.5degrees at right lateral gaze, and 74.9degrees at downward gaze. The value among different age groups was not statistically significant. The women had a broader field at left and right inferior area than the male (p<0.05). Korean had a larger right, left, and inferior field than Caucasian does. CONCLUSIONS: The differences of the field of binocular single vision between male and female are due to the differences in nasal architecture. The differences between Korean and Caucasian are due to differences of nasal architecture and facial structure. It may be useful in evaluating of strabismus and motility disorder if the normal field value of binocular single vision in Korean could be put under consideration. |
