Reliability of a modified logMAR distant visual acuity chart for routine clinical use.

Discussion The clinicians all over the globe are in consensus about the type of VA chart to be used for research purpose.[ 8 ] Disappointingly, for routine clinical use, the advantages of logarithmic progression acuity charts are conveniently eluded by blaming the time required to administer the procedure.[ 9 ] The importance of having the same standard of acuity measurement in research as well as in clinical situation is highly significant when we apply the outcomes from clinical trials (which typically assess the VA with logarithmic charts) to predict the outcomes in clinical practice (which prefers to use Snellen's chart).[ 10 ] This study demonstrated that the modified logMAR chart can produce acuity data that agree very well to the data produced by the gold standard logMAR chart [ Table 3 ].
