A). Designed for acuity measurement of children 6 months to 3 years. Also useful with other age groups with intellectual impairment, dementia, head injury, or stroke. Uses Preferential Looking to provide an excellent accuracy of diagnosis. The figure loses contrast at the acuity threshold. Thus resolution, detection, & recognition acuity thresholds are combined. Target figures are pictures in decreasing widths of white & black lines. Tests in 0.1 logMAR steps. Suggested distance is 0.5 meters or 1 meter with acuity equivalent from 20/320 to 20/12.5.

PREcisioN VisioN - gRatiNg PaddlEs USO2533 $269.95
Paddles with gratings are more interesting to infants than equally contrasted paddles. These paddles have black and white stripes that are set one cm per degree of visual angle at 2 feet. Preferential viewing has been proven accurate in several studies.
Patti Stripe paddles are highly useful for testing the contrast sensitivity of children, infants, and those with mental disabilities. The contrast sensitivity is tested by placing the gray paddle in front and the grated paddle behind and sliding it out. If the child can see the grating or contrast level, they will respond by following the paddle. The set includes seven separate CPCM gratings that help to establish a contrast sensitivity level in pediatric patients.
Patti Stripes consists of six gratings at 0.3, 0.6, 1.2, 2.4, 4.8 and 9.6 CPCM (cycles per centimeter) along with the CPD (cycles per degree) for the three test distances of 25, 50, and 100 cm (10, 20 and 40 in.) printed on the handle.
• Can be washed with soap and water or cleaned with alcohol.
• Extremely durable made from 4 mm plastic. These will hold up to years of service.
• Set includes four paddles, three with gratings printed on both sides and one solid gray face for presentation.
FacE dot tEstTM Developed by Jack Richman, O.D.
JRFDP $54.95
This tests for visual acuity in difficult-to-test pre-verbal
or nonverbal infants and children with low cognitive
or developmental functioning levels. The face is
an easily recognized target and provides a strong
attention stimulus for low functioning patients. The
test employs the use of contrast sensitivity in a
forced choice testing procedure. The results may be converted into an approximate visual acuity based on the testing distance.
The set includes three paddles that be used at different test distances to approximate visual acuity. Distance chart is on back of test paddle. Instructions for the different testing methods are also included.
