In a study that included 29 NCAA football players, repetitive subconcussive impacts were associated with changes in near point of convergence (NPC) ocular-motor function among players in the higher-impact group, although NPC was normalized after a 3-week rest period, according to a new study. The NPC measures the closest point to which one can maintain convergence (simultaneous inward movement of eyes toward each other) while focusing on an object before diplopia (double vision) occurs.
