Vision therapy the second

Introduction

The vision therapy adventure continues. My second round of appointments brought some new exercises for voluntary vergence control and some updated vision status measurements. I also suggested some VR applications to the vision therapist. Four more weeks of home exercises until the first follow-up with the doctor to check progress.

Starting vision therapy

Introduction

I have refractive amblyopia which is a condition where the brain tends to suppress sensory input from one eye due to poor vision in that eye (ambloypia). The refractive part is the cause, which is substantially worse vision in my right eye. Even though, with glasses, vision can be optically corrected for my right eye I am (neurologically) unable to see well with it, as the brain filters its input to protect overall vision.

My amblyopia leads to a number of vision issues: ocular cross-dominance (left-eye dominant with right-side dominance), depth perception inconsistency (though I have no issues with autostereograms), difficulty with object tracking, right-eye vision suppression, eye control issues, occasional double vision, and infrequent motor control challenges.

Historically, the professional consensus was that much past six years old, it wasn't possible to correct amblyopia due to decreased brain elasticity. After mostly unsuccessful attempts at patching starting around six, and with a few other false starts up to around eleven, I forget about the issue for many years. However, in 2018 I went to a new optometrist who suggested I might benefit from vision therapy.

I started vision therapy in January 2021. My goal is to document my experience with vision therapy and its impacts on my amblyopia in a series of blog posts over the course of the year. This first post covers my history with amblyopia, some of my subjective experiences with the condition, and my introduction to vision therapy.
