Abstract
This study examines the effect of adaptation on the prism vergence range following an induced deviation. Five young adult subjects, with normal binocular functions, underwent fusional verfence testing to base in prisms before and after wearing a 10(Δ) base out Fresnel prism. The Fresnel prism was worn for a period of 2, 5, or 10 min on each of three separate occasions. The base in fusional vergence showed no statistical difference before or after adaptation, for any of the time periods. Also there was no difference in the ranges obtained over the three time periods. It was concluded that, even after a 2 min period of adaptation, fusional vergences return to a similar level as before the horizontal deviation was induced.
