ABSTRACT
OBJECTIVE:
To determine whether central and peripheral vision reaction times (PVRTs) are prolonged in patients with visual dysfunction after sustaining a concussion.DESIGN:
Comparison of Dynavision D2 central and PVRTs in patients with postconcussion visual dysfunction were compared with control data from a normative patient database. Concussion patients without visual dysfunction were not included in this study.SETTING:
National Collegiate Athletic Association Division 1 college training room and university based, academic health center.PARTICIPANTS:
Patients were selected for inclusion based on diagnosis of new visual dysfunction as indicated either by physical examination of the team physician or by patient self-report of symptoms. Patients included college athletes, college students, and concussion patient's presenting to a university based, academic health center. INTERVENTION Measurement of central and PVRTs using a Dynavision D2 reaction time program were used as the dependent variables. Evaluations were conducted from 3 days to 11 months postconcussion, depending on the temporal development of visual symptoms after the concussion. No intervention was used. MAIN OUTCOMEMEASURES:
Average central and PVRTs for patients with postconcussion visual symptoms were compared with an asymptomatic control group with no history of concussion.RESULTS:
Both central and PVRTs were significantly prolonged in patients with postconcussion visual symptoms compared with patients with no history of concussion.CONCLUSIONS:
Central and PVRTs are both prolonged in patients with postconcussion visual dysfunction with PVRT being disproportionately prolonged. The percent change from central to PVRT was also increased in patients with postconcussion visual dysfunction.
