For me, the Waggoner Computerized Color Vision Test (Waggoner CCVT) has shown to be sensitive and reinforces the diagnosis (and level of severity). For example, when we look at an AMD patient, and even OCT this patient, all we have is an idea of structure. It doesn’t really tell me what is the function.

The Diopsys (also functional assessment) so far is running consistent with Waggoner Diagnostics’ color vision test. A patient may “look like” they have a fair amount of AMD in their OD but the Diopsys says the eye is functioning better than I would expect. Lo and behold, when I look at the color vision test, the tritan deficiency is less (or not even deficient) on the OD.

I had a Plaquenil patient this week. When you see the “flying saucer” on the OCT, we now know that’s a little later than desired. Ideally would like to pick up IS/OS separation, but to me that’s a challenge. I really like having the color vision to say - “all good”. I’m adding the multifocal ERG soon and that will help a lot with Plaquenil. We now know the deposits do NOT occur first under the fovea. So, getting some parafoveal info from color and MF ERG will be nice.

The same principle applies to glaucoma (optic neuropathy) and amblyopia. When doing color test monocularly, the results quickly validate the severity of the disease.
