A general review of fixation disparity and Panum's fusional areas preceeded a more specific discussion of vertical fixation disparity. Included were a summary of factors affecting fixation disparity, symptomatology and methods of prescribing for vertical imbalance. The Butler test was compared with the AO Nearpoint Vectographic Card #1 regarding their ability to detect induced vertical misalignment. Results of the parametric statistics, using a t-test, indicated that there was no significant difference between the two methods in detecting vertical misalignment.
