2022 Colorado COVD Study Group

Title: ABSees: Vision Therapy for Little Kids
Date: Sunday, March 13th, 2022
Time: 9:00am – 1:00pm

Bring: Bring your favorite activities for ages 0-5 and red/green glasses. Wear comfortable clothes for ease of movement. MASKS ARE REQUIRED, preferably well-fitting high-quality masks. Food: Potluck style! Bring a snack if you are able to. Nearby Food Truck park is also an option (Rayback Collective), which opens at Noon.

Course Summary: Guiding visual development with optometric vision therapy is an important tool for treating young children. The preschool age group often presents with amblyopia and strabismus, conditions that greatly impact visual performance and motor coordination. This course covers vision therapy techniques designed to decrease suppression, improve oculomotor skills, develop accurate accommodation, and improve eye alignment and sensory fusion. Learn how to modify therapy techniques for young children and how to successfully sequence vision therapy based on age and ability.

We are planning on holding the COVD Study group as planned at Boulder Valley Vision Therapy, and we will do everything that we can to make this a safe and fun event for all attendees. We ask that if you have any COVID symptoms in the 5 days prior to the event, that you please stay home, even if you are feeling well enough to attend.

Colorado COVD 2020 Winter Study Group

When: Sunday, February 23, 2020 from 9:00 AM to 12:00 PM (MST)

Where: Hellerstein & Brenner Vision Center, P.C.7400 East Orchard RoadSuite 175-SGreenwood Village, CO 80111

Topic: Testing and Treatment of Vertical Deviations

Presentors: Dr. Jennifer Simonson of Boulder Valley Vision Therapy and Dr. Lynn Hellerstein of Hellerstein & Brenner Vision Center, P.C.

Course Description: Dr. Simonson and Dr. Hellerstein will share clinical pearls in treating vertical diplopia. This course will discuss eye alignment, prism prescribing, and recommended vision therapy techniques to decrease symptoms of double vision. The goal is of this course will be to utilize compensatory and therapeutic strategies to improve fusion skills for patients with vertical strabismus and diplopia. During this workshop, attendees will complete hands-on training on clinical testing for vertical misalignment. Stations will include Maddox rod, Modified Thorington, laser-assisted Hess Lancaster, and other clinical techniques to measure the amplitude of misalignment and fusional ability. This training will help vision therapists understand the direction and amplitude of strabismus. Attendees will also experience induced vertical misalignment and determine optimal prism perscription based on findings. In addition, vision training concepts and procedures will be performed to increase the accuracy, stability, and concomitancy of eye alignment. Learn new techniques and appropriate procedure modifications.

Course is APPROVED for 3 hours of Colorado State licensure CE credit through COA.

Winter Colorado COVD Study Group 2018

A Novel Approach to Visual Information Processing Skills

Summary: Visual information processing skills (VIPS) have been assessed through a number of clinical assessments. We propose a paradigm shift in the assessment and treatment of VIPS. Through a unique method of analyzing VIPS testing results, we believe we can accurately project treatment times, predict efficacy of therapy, and easily alter traditional optometric VT activities in ways to provide faster, more stable therapy results. This course will cover the history and development of the model with sample cases to demonstrate interpretation.

Bio: Jeff Berger, O.D., FCOVD, graduated from NSU-OCO in 2009 and opened a primary care practice in Erie, Colorado in 2010. Shortly after opening, he began providing therapy services primarily to his own patient base. In 2016, he opened the Colorado Center for Visual Performance, a practice rendering only vision therapy services. He was thrilled to have the privilege of learning from and working with Dr. Bateman and Dr. Dowis during the development of this assessment.

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.
