Because the response to my first top 10 activities for vision therapy was positive (“Vision therapy: A top 10 must-have list,” August 2014), I have decided to once again revisit the topic. On the first list were some of the mainstays in the vision therapy room as well as a bonus item. In this installment, I will present a second set of 10 items that are essential to every vision therapy practice and expound in greater detail on one or two items from the first list.
In the Vision Therapy & Rehabilitation Service at Southern College of Optometry, there is no one way to perform vision therapy; this list and the previous are reflective of that point. Some doctors prefer computer programs and technical instruments, while others perform activities in free space. I like a bit of both, as you can tell. Regardless of which approach you may take, you are not wrong.
1. MFBF Matching Game
While this specific version of this activity is new on the market, the concept is not a new one. This activity uses the concept of monocular fixation in a binocular field, or bi-ocular, as some refer to it. This means that both eyes consensually react to the stimulus, but only one eye at a time actually sees the given stimulus. This is an intermediate step in accommodative techniques between monocular and binocular therapies.
In this set, there are clear acetates with black targets (pictures, numbers, and three grade levels of words), a red acetate that sits under the chosen acetate, and corresponding sets of white domino style tiles with red targets (see Figure 1). While previous iterations required a specific viewer on which to perform the activity, this one can be used with a standard lighted vectogram holder. While wearing red/green glasses, the patient locates and places the matching tiles on top of the red/clear acetate in the correct location (see Figure 2). If she cannot see either target or during the activity the targets start to disappear, the patient is suppressing and a larger target should be used. This activity can be made more challenging with the addition of plus and minus lens on opposite eyes to turn up the burner on relaxing and stimulating accommodation.
