Description
The only symbol test of its type with the stated objective of calibration targeted to equal Sloan letters used in the ETDRS® charts. This uniformity is especially important when taking patients from symbols to letter tests. Other tests are either much easier than ETDRS® charts or they are outdated and no longer relevant. Both are very significant factors when a child has an eye disorder or amblyopia and they advance to clinical letter charts.
