During a TPA exam pre-test, if a patient reports loss of vision in one eye, what should you consider regarding visual acuity testing?

In the context of visual acuity testing during a TPA exam pre-test, if a patient reports a loss of vision in one eye, it becomes important to assess the extent of the visual impairment and its impact on overall visual function. Although it may seem that testing the affected eye is unnecessary due to the reported visual loss, this approach allows for a clearer understanding of the patient's condition.

Testing the visual acuity of the affected eye can provide valuable information about the severity and nature of the visual problem. It may reveal the degree of vision loss, which can be relevant for diagnosis, management, and treatment planning. Moreover, baseline documentation of the affected eye's acuity can be crucial for monitoring potential changes over time, especially if the condition progresses or improves. Therefore, while it may initially feel redundant, proceeding with visual acuity testing for the affected eye serves multiple clinical purposes, including patient care and comprehensive assessment.
