Arabic visual acuity chart for low vision examination.
An Arabic visual acuity chart has been designed for low vision examination, using ten Arabic letters constructed on a 5 x 5 framework. The chart contains seven pages with acuity values ranging from 20/600 to 20/80, corresponding to letter sizes of 26.5-3.5 cm. Interletter spaces were made one-fifth the size of each letter in a row while inter-row spaces were made equal to the height of the letters in the row below. The chart will be useful to eye care practitioners who may wish to use Arabic charts in low vision evaluation.
