Tritheia was written by Dr. Zurcher with the intention of modernizing his existing vision therapy practice.
  • Don’t re-invent the wheel

We all know that traditional vision therapy works well.  We also know that the computer can do some unique things, but is not a substitute for self-directed activity, balance, body movement, and human interaction.   The goal of Tritheia is to help keep VT practice better organized, reduce repetitive/monotonous tasks, and help integrate computer activities into your VT programming if you choose to.

  • Customizable

Doctors and therapists who work in vision therapy tend to be creative people.  We make a lot of our own materials.  We customize our activities and programs.  Tritheia allows you to create your own custom content such as  variable anaglyphs,  images for presentation, word lists,  and stories.  You can create your own activities, edit instructions, create templates to document sessions, customize report templates.  You can create pre-set programs for specific purposes (like a GBD program,  amblyopia program, testing results, etc.)  You can also create and customize programs for individual patients.

  • Share with Others

Activities and content that you create can be exported to a file.  You can freely send them to anyone who can then import them to their system.

  • Adjustable

Let’s use a basic letter chart as an example.  What if it is too difficult for the patient?  You might increase the font size or reduce the number of columns or rows.  What if they are an amblyope?  You may want to display it to be only visible with one eye using red/green glasses.  What if they suppress?  You may want to have some of the letters visible to the left eye and some visible to the right eye to control suppression.  What if it’s too easy?  You could make it move in a circular motion around the screen.

  • Keep Instructions Organized

You can edit your activity instructions from within the software.  Add Pictures, lists, tables, etc.  You no longer need filing cabinets full of copies of copies.

  • Reproducible Metrics

Tritheia uses units such as prism diopters and Snellen letter sizing.  A stimulus displayed on a patient’s home computer should be the same as what worked for them in your office (assuming they measured correctly.)

  • Web Connected

The Tritheia server is  accessible from any computer connected to the internet.  This provides a lot of flexibility in terms of how and who you want to use it.  You can have patients can use it at home.  You could use it to collaborate with other professionals such as OT’s.  You could also use it to help co-manage your VT patients with other OD’s.

  • Monitor Progress

By having your patients do some computer activities you can get a feel for compliance and monitor performance.

  • Manage Equipment

Keep tabs on your equipment.  Edit its description and cost to replace.   Associate a piece of equipment with a certain activity.  Check it out to patients.  Look up who has what checked out.
