In the Clinical Sciences article by Graf and Roesen titled "Ocular Malingering: A Surprising Visual Acuity Test," published in the June issue of the ARCHIVES(2002;120:756-760), an error occurred in the "Introduction" on page 756. In the right-hand column, first paragraph, the sentence beginning on line 8 should have read as follows: "The probability of a maximum number of correct responses(k) out of 32 optotypes with 4 possible alternative answers can be determined by the distribution function of the binomial formula: If k = 1, P≈.001; if k = 2, P≈.007; and if k = 3, P≈.03."
