To report the visual functional parameters of quarterback football players.
Retrospective review of charts of college quarterback players who have undergone routine visual screening. Subjective ocular history, visual acuities, means of vision correction, residual refraction with correction, contrast sensitivity, color vision, and stereopsis were collected. Humphrey Field Analyzer full-field 120-point screening tests were evaluated and performance on the test was compared to healthy age-matched non-athlete controls.
Eighteen eyes of 9 quarterback football players were included. Mean visual acuity was 20/18 (range 20/15 to 20/25-2) with 2 players using soft contact lens correction and no player with a history of refractive surgery. The mean Vistech VCTS 6500 contrast sensitivity chart score was 5.72, 5.89, 5.61, 5.89, and 6.00 for a spatial frequency of 0.5, 1, 2, 4, and 6 cycles per degree respectively. Color vision was 10/10 Ishihara plates for all player, and stereopsis was better than 40 seconds of arc on the Titmus test. Performance of the screening visual field was of good reliability for all players. Testing duration for the visual field test was significantly shorter in players compared to controls.
Establishing baseline visual function for football players in various positions can serve as a guide when evaluating and correcting vision to the level needed for the sport. The faster performance on visual field screening may reflect a fast reaction time for quarterbacks.
