title: Models of mutual interactions between accommodation and convergence.
abstract: Several possible models of interactions between accommodation and convergence are compared. Accommodative and fusional vergence effort are predicted for each model using the same set of clinical data. Only one model makes predictions that are consistent with clinical and laboratory observations of fixation disparity. The results support the clinical use of graphical analysis of mutual interactions between accommodation and convergence in the diagnosis of accommodative vergence disorders.
