Screening efficacy of a simplified logMAR chart [PDF]
African Vision and Eye Health, 2016 Background: Snellen acuity charts are the most commonly used method for visual acuity (VA) testing in screening programmes despite comparative studies verifying that the logarithm of minimum angle of resolution (logMAR) acuity measurement charts are more

Reliability of a modified logMAR distant visual acuity chart for routine clinical use
Oman Journal of Ophthalmology, 2012 Background/Aim: Acuity charts that follow the principle of logarithmic size progression (logMAR charts) are considered to be the gold standard for the assessment of distant vision. But it is not well accepted for routine eye examinations due to increased

A practical logMAR near reference table for low vision practitioners: Design and applications [PDF]
African Vision and Eye Health, 2006 LogMAR charts are particularly useful for visual acuity (VA) measurement for low vision patients as they simplify conversion of non-standard viewing distance visual acuities to standard values.

Construction and validation of logMAR visual acuity charts in seven Indian languages
Indian Journal of Ophthalmology, 2018 Purpose: The evaluation of visual impairment requires the measurement of visual acuity with a validated and standard logMAR visual acuity chart. We aimed to construct and validate new logMAR visual acuity chart in Indian languages (Hindi, Bengali, Telugu,

Programming a LOGMAR calculator into a REDCap database
Eye, 2022 [Extract] LOGMAR (logarithm of the minimum angle of resolution) is a common modality for reporting visual acuities academically. However, Snellen charts are the predominant tool of visual acuity measurement clinically. Online calculators convert individual Snellen acuities to LOGMAR, but this is labour intensive and invites error from manual data ...

A comparison of two methods of logMAR visual acuity data scoring for statistical analysis [PDF]
African Vision and Eye Health, 2009 The purpose of this study was to compare two methods of logMAR visual acuity (VA) scoring. The two methods are referred to as letter scoring (method 1) and line scoring (method 2). The two methods were applied to VA data obtained from one hundred and forty (N=140) children with oculocutaneous albinism.

Crowded letter and crowded picture logMAR acuity in children with amblyopia: a quantitative comparison [PDF]
British Journal of Ophthalmology, 2016 Aims Clinically, picture acuity tests are thought to overestimate visual acuity (VA) compared with letter tests, but this has not been systematically investigated in children with amblyopia. This study compared VA measurements with the LogMAR Crowded Kay Picture test to the LogMAR Crowded Keeler Letter acuity test in a group of young children with ...
