title: Reliability and validity of the dot visual acuity test.
abstract: The reliability of the dot visual acuity test (DVAT) was demonstrated using the test-retest method. The test, however, was not found to be valid when comparing it with the Sjögren test. Since the DVAT has previously been shown to be valid when compared to the Tumble E test, these results bring into question the validity of the Sjögren test when compared to the Tumble E test.
