Increased sensitivity with decreased numbers of test points and decreased test field size in automated perimetry of normal subjects.
Mean sensitivity (MS) was compared among programs with different numbers of test points and different test field sizes with an automated perimeter in normal subjects. The programs tested were designed by the program Sargon. Within a 10-degree visual field the MS was significantly higher with fewer test points and with a smaller test field size. The MS between 10 and 25-degree fields increased under the same conditions. Increased MS was found with decreased numbers of test points and decreased test field size within 25 degrees in automated perimetry of normal subjects.
