Convergence is a disconjugate movement in which both eyes rotate inward so that the lines of sight intersect in front of the eyes. Zhu, M., Collins, M. J., & Iskander, D. R. (2006). (1994). Leigh and Zee[ 4 ] offered a mechanism for this abnormal ocular movement in the setting of horizontal gaze, suggesting synchronized coexistance of the vergence and version system in conjugate eye movement. Extraocular muscle movements were normal and eyes looked fairly aligned.

The frontal eye field is known to have extremely short visual response latencies (Pouget et al., 2005), most likely mediated by subcortical pathways. Convergence insufficiency is a common condition that is characterized by a patient 's inability to maintain proper binocular eye alignment on objects as they approach from distance to near.

In each eye, the visual axis will point towards the object of interest in order to focus it on the fovea. The cause of Convergence disorder is unknown and researchers are still working on it. Logvinenko, A. D., & Steinman, R. M. (2002). Edwards, M., Pope, D. R., & Schor, C. M. (1998). For example fish accommodates through the change of position of the lens, some types of birds accommodate through the increase of curvature of the cornea and protraction of the human eye. Logvinenko, A. D., Epelboim, J., & Steinman, R. M. (2002). … Human eye - Human eye - Movements of the eyes: Because only a small portion of the retina, the fovea, is actually employed for distinct vision, it is vitally important that the motor apparatus governing the direction of gaze be extremely precise in its operation, and rapid. Vergence eye movements consist of convergence, wherein the coordinated contraction of both medial rectus muscles brings both eyes toward the midline (ie, the nose), and divergence, wherein the coordinated contraction of both lateral rectus muscles brings both eyes toward the periphery.
