Course Title: Prism, Prism, Prism!
Part I: Prism Prism Prism Part 1 Handout Simonson
This course is an introduction to the use of prism in order to improve sensory perception and oculomotor control. This course will discuss monocular, bi-ocular, binocular and yoked prism use in vision therapy.
Part II: Prism Prism Prism Part 2 Handout Simonson
This workshop will provide hands-on experience and demonstration of vision therapy procedures. Participants will complete training using prism bars, prism flippers, loose prism, Risley Prism, prism glasses, and yoked prism. Techniques will include monocular, bi-ocular, binocular and yoked prism activities.

Course notes for “Therapeutic Prism – Vision Training Workshop”
Dr. Jen Simonson & Staff
We used the idea that “Therapeutic” meant that you were challenging the visual system vs. using prism in a compensatory way.
The goal of these exercises is to use prism in order to improve sensory perception and oculomotor control.

COVD 2015 Poster: Van Orden Training Utilizing the Stereoscope for iPad
BACKGROUND: Millard E. Van Orden developed a stereoscopically drawn visual pattern to gain insight on the patient’s binocular visual behavior pattern. This drawing records the projection in space of corresponding visual areas. When used for training, the patient receives feedback on the reorganization of visual space and stability of eye posture and binocular vision.
PROCEDURES: Van Orden drawings were completed with the Translucent Correct-eye-scope set at 0-0 and the Stereoscope for iPad set at 0 (optical far-point). The optics of the prismatic lens allow for a distance accommodative and vergence demand, but a physical distance of 20 centimeters. Targets included binocular vision space testing, far point – peripheral control, base-in projection stereo training, and base-out projection stereo training. Instructions were the same for both the traditional and digital drawings and followed the Van Orden Technique of Visual Rehabilitation Instruction Manual (Keystone View Company, www.keystoneview.com/download_manuals/6104_van_orden.pdf)
Dr. Simonson presented a poster at the 2015 COVD Annual meeting.
1. Ability to complete testing and training in more postures with the same device (standing or sitting, primary gaze or up/down gaze)
2. Ability to add images to electronic health records for performance documentation.
3. Ability to test visual performance when viewing a digital device (clinically noted to cause more visual complaints).

Thank you for submitting your abstract, ” Van Orden Training Utilizing the Stereoscope for iPad”, to the 2015 COVD annual meeting. The review process has concluded, and we are pleased to inform you that your abstract was accepted, to be presented as a poster. It is scheduled to be displayed on Thursday, April 16 and Friday April, 17 2015 on poster board #29.
I really enjoyed the opportunity to speak during the general education program of the 2014 College of Optometrists in Vision Development Annual Meeting. Part of the reason I wanted to do this is because presenting to a group lets me research and organize my thoughts on a particular topic. In this case, it was treating vertical strabismus with vision therapy. I hope this information is helpful to you in clinical practice! – Dr. Simonson

COVD 39th Annual Meeting
October 13-17, 2009
Denver Marriott Tech Center
Our staff will be completing a 2 year certification process at this year’s annual meeting. Two thousand hours of experience are required before seeking certification. Our therapists have written and submitted papers on such topics as strabismus, amblyopia, focusing disorders, tracking skills, eye teaming ability, and therapeutic techniques. All papers were accepted earlier in 2009. All therapists have also completed a proctored written examination on their vision therapy knowledge. On October 13th, Amy, Barbara, Gail and Krystal will take their oral exams. Keep them in your thoughts! We have been completing 2 hours of additional training every Monday since November 2008 in preparation for this milestone.
