Description
The purpose of this paper is to compare the results obtained when visual acuity is measured in the low vision patient using two acuity charts: the Projecto-Chart snellen letters and the Feinbloom Designs for Vision Chart. Data was compiled over a three month period in the
same examination room under the following conditions: Projecto chart illuminance was held constant at 14 foot candles; this illuminance was matched on the Feinbloom chart by using a goose-neck lamp with silver backing and a 60 watt bulb. Monocular visual acuities were obtained on 16 patients who were corrected to their best acuity (spectacles only). No filters or telescopes were used. Acuities were measured at 14 feet with the projecto chart (calibrated to be a 20 foot equivalent) and at 10 feet for the Feinbloom chart. |
