Which of the following lists are assessment tools used for vision and visual perception in TBI?

• A. Visual acuity tests; Visual field testing; Vestibular function tests
• B. Visual acuity tests only
• C. Color vision testing
• D. Hearing screening

Answer: (A)

In traumatic brain injury, evaluating vision and how things are perceived visually involves more than just how clearly someone can see. Visual acuity tests measure the sharpness of central vision, which tells you how well a person can discern fine detail. Visual field testing looks at the full range of vision, identifying any peripheral field losses that can affect scanning, reading, and navigating environments. Vestibular function tests assess balance and gaze stabilization, which influence how we visually perceive motion and maintain stable vision during movement. Together, these three areas cover both the clarity of vision and how vision is integrated with perception and function, making this combination the most comprehensive choice.

Testing only visual acuity misses important deficits in the visual field and in vestibulo-ocular control. Color vision testing, while useful in some contexts, does not address the broader range of vision and visual perception problems seen after TBI. Hearing screening does not assess vision at all.
