CHARLESTON, SC (WCSC) - A new study just released today suggests concussions are not the only injury of concern to football players.
Researchers found short-term changes in eye function following repetitive subconcussive impacts. Those hits do not result in concussion, but happen more often, and are believed to cause long-term neurological problems.
The researchers studied five football practices for 29 NCAA Division 1 players, and found repetitive subconcussive hits affect eye motor function. Changes were noted in near point of convergence, the closest point players could move their eyes, focusing on an object, before having double vision.
The researchers found NPC was normal after players rested three weeks.
The study, published in JAMA Opthalmology, notes players are subject to as many as 1,300 subconcussive head impacts per season.
While more research is needed, one expert said if confirmed, the findings could support a call for limiting full contact practices in collision sports.
