Interpretation. Each eye is tested separately. The lowest line the patient can accurately read indicates the patient’s visual acuity. The lines on the Snellen chart contain “distant equivalent” values. For instance, the top line is 20/800, which means if that line is the lowest line the ...
6.2.1 Visual acuity Optimal visual acuity measurements (sections 3.2 and 3.3) that are different in the two eyes or are reduced compared to age-matched normal values indicate some ocular abnormality and must be explained. A pinhole visual acuity test should be used to make sure that the reduce...
Mean age at VA test was 7.6 years. An IOL was implanted in 294 eyes (88.6%; 95% CI, 84.8%-91.8%). Visual acuity in pseudophakic eyes ranged from 20/16 to worse than 20/800, with 107 of 294 eyes (35.5%; 95% CI 30.0%-41.5%) achieving age-normal values (Figure 1). Visual ...

Visual acuity (VA), the cornerstone of eyecare, can yield symptoms despite 20/20 [1]. Optimal VA is 20/10 based on cone spacing. Vernier acuity (minimum misalignment) is 3” arc, 10x < cone spacing, ahyperacuitymediated by visual cortex [2,3,4]. Minimum visible acuity [2] (MVA...
Before measurement began, the whole class was briefed on the test procedure and were assured that we were not going to touch their eyes during testing. Distance habitual VA (with spectacles if worn) was measured using a single Bailey-Lovie LogMAR acuity chart at four metres, in a room well...

Interpretation deemed arbitrary VA recorded as 20/020, possible VA interpretations include 20/20, 20/200, 2/200 (“200-size letter E”) CF = counting fingers; NI = no improvement; NLP = no light perception; VA = visual acuity. ∗ Data dictionary: internal standard listing of VA line ...
