A prospective study of different test targets for the near point of convergence

Ophthalmic and Physiological Optics, 2010
AbstractPurpose:  To determine whether different test targets including an accommodative target (AT), a transilluminator (TR), and a transilluminator with a red lens (RL), affect the near point of convergence (NPC) value; and to determine which test target is most sensitive to identify convergence insufficiency (CI) in young adults.Methods:  Subjects ...
