Attached 16-inch (40cm) cord ensures proper testing distance. Response key printed on test card. Flash cards and instructions included. 8" x 10" (20.3 cm x 25.4 cm).
Illiterate Tumbling E ETDRS vision chart with proportionally spaced (geometric progression) lines; line sizes range from 20/200 to 20/10 (6/60 to 6/3) equivalent.
The Spatial Board was suggested by Dr. Streff as a way of quantifying and recording spatial localization shifts with patients. Dr. Kraskin utilized similar assessments of a patient's spatial localization in order to determine the amount and direction of yoked prisms to prescribe.
The VTE Spatial Localization Board is designed for clinical efficiency to allow the behavioural optometrist to quickly assess a patient's spatial localization in real space and time; determine x, y and z axis spatial warps in 9 primary meridians; record patient responses for pre and post test data (especially good for documenting mid-line shifts in TBI and strabismic patients) and quantify immediate effects of lenses and prisms.
