Used to measure Afferent Pupillary Defects (APD) which is defined as diminished pupil reaction to light levels. It uses 6 standard ND levels for quantifying APD. The log units quantify amount of light transmitted through the filter. Includes 6 filters rated as 0.3, 0.6, 0.9, 1.2, 1.5, and 1.8 log unit optical density values. The 0.3 ND filter is most useful for uncovering a borderline pupil defect.

  • The filter bar can be used in conjunction with the “Swinging Flashlight” test to detect and quantify the depth of any afferent conduction defect.
  • Each filter measures 7/8" by 1" (2.5cm x 3 cm).
