Sanet2019b

Dr. Bob Sanet

This 2-day course will provide attendees with an understanding of amblyopia and strabismus including eccentric fixation and anomalous correspondence and effective evaluation techniques to determine the prognosis in amblyopia, exotropia and esotropia. The course will provide an overview of myths and misconceptions regarding amblyopia and strabismus and review scientific studies on the underlying cause of amblyopia and strabismus and treatment options including patching, surgery and optometric vision therapy. This course will conclude with easy-to-follow, sequential and effective vision therapy treatment procedures for amblyopia, exotropia, and esotropia.

Dates: October 11-13, 2019

Location: Barclay Lodge, YMCA of the Rockies, Estes Park, Colorado

 

 

This event is held next to Rocky Mountain National Park. The closest airport is Denver International Airport. I recommend renting a car for the 2 hr(ish) drive. Fastest route takes the E-470 Toll Road. If you have more time, take Pena to 36 and visit Pearl Street in Boulder, CO for lunch on your way up. There are also several restaurants in the City of Estes Park, Colorado. Even more time? visit the National Park for a hike or scenic drive. Our event starts with dinner at 5 pm at the Barclay lodge.

Join us Sunday February 24, 2019 at Western University College of Optometry
At this year’s practicum, Dr. Simonson will share some of her most coveted pearls and strategies for young patients with special needs/developmentally delayed and physical handicaps. She will review normal versus delayed visual development from general motor concepts to development of visual perception and motor output for reproduction. You will gain insight into a systematic approach to vision therapy procedures for these young cases.
