divergence insufficiency

A binocular vision disorder where there is a higher esophoric or intermittent esotropic deviation at distance compared to near fixation. The eyes have difficulty diverging or turning outward to view distant objects, while the deviation is much lower or absent at near. This condition can lead to diplopia or suppression when viewing distant targets. It is frequently associated with convergence excess or high accommodative convergence/accommodation ratio and may require treatment with prism, vision therapy exercises, or surgical intervention depending on the severity.
