LogMAR and Stereoacuity in Keratoconus Corrected with Spectacles and Rigid Gas-permeable Contact Lenses.
Nilagiri VK, Metlapally S, Kalaiselvan P, Schor CM, Bharadwaj SR. Nilagiri VK, et al. Optom Vis Sci. 2018 Apr;95(4):391-398. doi: 10.1097/OPX.0000000000001205. Optom Vis Sci. 2018. PMID: 29554011 Free PMC article.

Only monocular logMAR acuity of affected eye and stereoacuity improved from spectacles to RGP contact lenses in the unilateral keratoconus cohort (P < .001). There was no significant change in the binocular logMAR acuity from spectacles to RGP contact lenses in t

Saving space: Comparing mini - logMAR with standard logMAR visual acuity.
Kauser F, Amitava AK, Saxena J, Raza SA, Masood A, Alam MS. Kauser F, et al. Indian J Ophthalmol. 2021 Jan;69(1):48-51. doi: 10.4103/ijo.IJO_2391_19. Indian J Ophthalmol. 2021. PMID: 33323571 Free PMC article.
The objective of this study was to compare the performance of distant VA (DVA) on one meter mini-logMAR (MLM) with a standard six meter logMAR (SLM) chart. METHODS: We developed a MLM chart to be used at 1 m with +1.0 D spectacles, by reducing the SLM chart designed …

The logMAR Kay picture test and the logMAR acuity test: a comparative study.
Elliott MC, Firth AY. Elliott MC, et al. Eye (Lond). 2009 Jan;23(1):85-8. doi: 10.1038/sj.eye.6702990. Epub 2007 Sep 28. Eye (Lond). 2009. PMID: 17901881 Clinical Trial.
The amblyopia was defined as severe/moderate (< 0.250 logMAR), n=41 or mild (> or = 0.250 logMAR), n=10. Visual acuity was assessed uniocularly using the crowded and uncrowded logMAR acuity tests and the logMAR crowded and uncrowded Kay picture t …

Crowded letter and crowded picture logMAR acuity in children with amblyopia: a quantitative comparison.
O'Boyle C, Chen SI, Little JA. O'Boyle C, et al. Br J Ophthalmol. 2017 Apr;101(4):457-461. doi: 10.1136/bjophthalmol-2015-307677. Epub 2016 Jul 7. Br J Ophthalmol. 2017. PMID: 27388249 Free PMC article.
RESULTS: The Kay Picture test significantly overestimated VA by 0.098 logMAR (95% limits of agreement (LOA), 0.13) in the amblyopic eye and 0.088 logMAR (95% LOA, 0.13) in the fellow eye, respectively (p<0.001). ...Due to the predictable difference found between …

[HYBRID MONOVISION].
Studený P, Kacerovský M, Kacerovská J, Gajarová N, Straňák Z. Studený P, et al. Cesk Slov Oftalmol. 2017 Spring;73(1):13-16. Cesk Slov Oftalmol. 2017. PMID: 28639448 Free article. Czech.
In non-dominant eyes, with implanted multifocal intraocular lens, UDVA improved from 0.30 0.23 logMAR preoperatively to -0.04 0.06 logMAR. The average binocular UDVA (bUDVA) was -0.07 0.08 logMAR and binocular CDVA (bCDVA) -0.12 0.06. The average UNVA in domi …

Evaluating a new logMAR chart designed to improve visual acuity assessment in population-based surveys.
Bourne RR, Rosser DA, Sukudom P, Dineen B, Laidlaw DA, Johnson GJ, Murdoch IE. Bourne RR, et al. Eye (Lond). 2003 Aug;17(6):754-8. doi: 10.1038/sj.eye.6700500. Eye (Lond). 2003. PMID: 12928690
Performance indices were test-retest variability (TRV) and agreement with acuity data measured using the ETDRS logMAR chart which acted as the 'gold standard'. RESULTS: The 95% confidence limits for TRV of RLME acuity data were +/-0.15 logMAR. This figure is consist …

Reliability of a modified logMAR distant visual acuity chart for routine clinical use.
Noushad B, Thomas J, Amin SV. Noushad B, et al. Oman J Ophthalmol. 2012 May;5(2):87-90. doi: 10.4103/0974-620X.99370. Oman J Ophthalmol. 2012. PMID: 22993462 Free PMC article.
RESULTS: The test-retest variability of the charts was comparable, with 95% confidence limit of the mean difference being 0.08 for standard logMAR and 0.10 for modified logMAR. Both the versions of modified logMAR charts produced the results which agreed well …

Is conversion of decimal visual acuity measurements to logMAR values reliable?
Mataftsi A, Koutsimpogeorgos D, Brazitikos P, Ziakas N, Haidich AB. Mataftsi A, et al. Graefes Arch Clin Exp Ophthalmol. 2019 Jul;257(7):1513-1517. doi: 10.1007/s00417-019-04344-9. Epub 2019 May 8. Graefes Arch Clin Exp Ophthalmol. 2019. PMID: 31069515
VA was the smallest line whereby four of five optotypes were correctly identified. Decimal scores were converted to logMAR using the formula logMAR = -log(decimal acuity). The agreement between VAlog, VA4m, and VA6m was assessed by the Bland-Altman method. ...There …
