'Indian' numerals, which are popular among the Arab population, were used to devise a new Snellen's visual acuity chart. The new chart has the advantages of a reading chart. It keeps the patient's interest, does not miss alexic patients, and is quicker to perform. It is also devoid of the many disadvantages of a kinetic response chart (the capital E letter or Landolt's broken rings), especially...

Subjective refractions without cycloplegia were examined with the Occlupad (Japan Focus Co., Ltd., Tokyo, Japan...
متن کاملLETTER TO THE EDITORS A CHART DEMONSTRATING VARIXTiONS IN ACUITY WITH RETINAL POSITION Visual acuity

This critical dimension can be the gap in a Landolt C, the spatiat period of a grating or the offset of a vernier. etc. Acuity declines progressively from the fovea out to the periphery of the retina. It is down to half its maximum value at an eccentricity of only 30 min according ...
