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. -

These offer excellent cancellation with no ghost images. These fixed demand targets provide flat fusion from 1-3 prism diopters, 2nd & 3rd degree fusion from 4-28 PD. BI & BO therapy is possible using a R/G flipper or switching the lenses in the goggles. (Set of 5 cards and one R/G Flipper) -
7-1/2" x 5-1/2" Non-Variable Polarized vectograms ensure testing and training at actuall distances. vectograms stabalize fusion and steropsis, eliminates suppression and develop simulatneous vision. Used in monocular, binocular pursuit and saccadic training, vectograms help correct and prevent anomalies involving projection and hand eye coordination. Ideal for use with Bernell's Dual Polachrome™ Trainer -
These photographs come on heavy-duty 8-1/2" x 11" cardstock for durability. There are activity suggestions printed on the back of each card. Some photos are identical in everything except the type of vergence demand or the amount of vergence demand. These were designed for the offices who work with just noticeable differences (JND) with their patients. Item #: HDSPVP -
Phoria Cards Test vertical and horizontal muscle balance at near and far. Used with Maddox Rod and Penlight. Referral considerations indicated on cards for imbalance beyond certain prism diopters or balance beyond specified esophoria and exophoria ranges. Shows phoria to parents!Item #: BC1209+ -
Variable Tranaglyph™ Kit (600 Series) Appropriate for a wide range of problems including strabismic and non-strabismic orthoptics.
