Visual AcuityAdultAgedAged, 80 and overPURPOSE: The optimal method for scoring visual acuity measures is unknown. Our goal was to determine, in a clinical setting, the method of scoring visual acuity with the lowest test-retest variability. METHODS: We investigated the effect of three different ...
The Tumbling E-test(ETDRS based) is a test of visual acuity. The results are based on the logMAR scoring metric - the Line Scoring Method. The corresponding dec…
Although the association between visual acuity (VA) and vision-related quality of life (VRQoL) has been well reported in patients with type 2 diabetes mellitus (T2DM), little is known about how unilateral and bilateral VA affects daily performance in such patients. For this cross-sectional study...
Test Modes: 1. Manual. 2. Auto scoring In Auto scoring, you use the swiping gestures to indicate correct readings or wrong readings, and the app calculates the score. Through enabling “Record Scores” in Settings, you can keep track of the progression of your visual acuity. Visual acuity ...
ObjectiveTo characterize habitual visual acuity, contrast sensitivity, spectacle use, and eye care utilization in a large sample of older adults residing
Performance of a computerised visual acuity measurement device in subjects with age-related macular degeneration: comparison with gold standard ETDRS chart... The aim of the study was to compare the performance of two different COMPlog computerised, single letter scoring, visual acuity (VA) measuremen...
Therefore, for these analyses, we used presenting acuity and contrast sensitivity in the better seeing eye. Outcome measures: performance on tasks Details on the tasks and scoring procedures are described elsewhere.12,13 For the purposes of this study, we chose performance-based tests in 3 ...
The inclusion for rehabilitation of visually impaired children is partly based on the measurement of near vision, but guidelines for near visual acuity assessment are currently lacking. The twofold purpose of this systematic review was to: (i) provide an overview of the impact of the chart design...
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...
