Vision Therapy System for use in a doctor's office and/or for use by the patient at home to help prevent regression between office visits. Provides a therapeutic approach for reducing patients' symptoms related to their binocular dysfunction while improving their visual performance and reading efficiency.
1071PL-LS - Large Saccadic Polarized Variable Vectograph
Treatment Vectograph with four rows of saccadic Fixation Disparity Cross stimuli presented at a 20/100 acuity level, reflective of the visual demands of larger print books. Fixation Disparity Target stimuli with Number Central Fusion Lock help relate binocular alignment to accommodation (clarity of the target). Total accommodation range of 40 diopters.
Includes: Manual & Standard Polarized Viewer
1071PL-SS - Small Saccadic Polarized Variable Vectograph
Treatment Vectograph with five rows of saccadic Fixation Disparity Cross stimuli presented at a 20/63 acuity level to monitor visual, binocular & accommodative functions more reflective of reading demands at higher grade levels (smaller print books). Fixation Disparity Target stimuli with Number Central Fusion Lock help relate binocular alignment to accommodation (clarity of the target). Total accommodation range of 40 diopters.
Includes: Manual & Standard Polarized Viewer
1071PL-SFD - Small Fixation Disparity Polarized Target
Vectographic two-dimensional card with 2 Fixation Disparity Crosses positioned vertical to one another to facilitate the comparison of binocular performance when using a lower versus higher spatial frequency or acuity demand. Top Fixation Disparity Cross at 20/95 acuity level reflective of visual demands of larger print books and bottom Fixation Disparity Cross at 20/63 acuity level more reflective of reading demands at higher grade levels (smaller print books). Sensitive to suppression and measures vertical & horizontal binocular function for assessing Near Point of Fixation Disparity (NPFD) (50 inches / 127cm) & Associated Vergence Measures at Near (16 inches - 18 inches/ 41cm - 46cm). Two-dimensional Fixation Disparity Cross stimuli with E Central Fusion Lock help relate binocular alignment to accommodation (clarity of the target).
1071PL-LFD - Large Fixation Disparity Polarized Target
Vectographic two-dimensional card with 2 Fixation Disparity Crosses positioned vertical to one another to introduce the new Fixation Disparity Cross design (bottom cross at 20/100 acuity level), as used as saccadic stimuli in the Binocular Accommodative Saccadic Series (BASS-PL), and to facilitate comparison to the standard Fixation Disparity Cross (top cross at 20/95 acuity level) as used in the Binocular Vision Dysfunction Diagnostic & Treatment System (P/N 1070PL). Sensitive to suppression and measures vertical & horizontal binocular function for assessing Near Point of Fixation Disparity (NPFD) (50 inches / 127cm) & Associated Vergence Measures at Near (16 inches - 18 inches / 41cm - 46cm). Two-dimensional Fixation Disparity Cross stimuli with E Central Fusion Lock help relate binocular alignment to accommodation (clarity of the target)
1071PL-RL - Randomized Large Fixation Disparity Polarized Target
Assessment tool for measuring binocular/accommodative function during a saccadic eye movement task using a sequence of saccadic identification targets. Vectographic silvered card with four rows of saccadic Fixation Disparity Cross stimuli presented with a 20/100 target size, reflective of the visual demands of larger print books. Two-dimensional Fixation Disparity Cross stimuli with Number Central Fusion Lock help relate binocular alignment to accommodation (clarity of the target). Answer Key imprinted on back of card for checking number accuracy.
