Customer: replied 1 year ago.


Yes, I'm back now.

Expert:  Dr. Tom replied 1 year ago.
Wonderful, so let's start at the beginning of your inquiry regarding color vision. Please let me know specifically what you would like to learn from this conversation.
Customer: replied 1 year ago.

I'm wondering about the color vision portion of the Titmus and how it is administered. As I understand, it is part of the exam done on the Titmus machine.

Expert:  Dr. Tom replied 1 year ago.
The Titmus testing instrument has several components. It is primarily used to test visual acuity. It can determine whether one is capable of seeing 2020, or anything else to legal blindness. It also has the color vision screening capability. It is administered by a technician, who will typically ask the patient to lean forward so that their fore head is resting against a sanitized head piece, and with both eyes open asked to report what they see. The color vision test objects are seen by each eye and the patient reports what they see. The technician records what the patient tells her. Using theTitmus is for screening purposes, however the color test objects are based on another, more sophisticated color vision testing modality. If the patient performs normally on the color vision screening there would be no further color vision evaluated indicated. Please let me know if this answers your questions and was what you are looking for.
Customer: replied 1 year ago.

What is this other, more sophisticated modality for color vision testing?

Expert:  Dr. Tom replied 1 year ago.
There are several more sophisticated color vision testing modalities. Three of the most common are Ishihara, Dvorine and Farnsworth D-15. The Titmus test is based on the Ishihara pseudo-iso-chromatic model.
Expert:  Dr. Tom replied 1 year ago.
I am Still available for further conversation, so please let me know if there's anything further you would like to chat about, regarding color vision testing.
Customer: replied 1 year ago.

Is there a way to know in advance how to answer the color portion of the Titmus test?

Expert:  Dr. Tom replied 1 year ago.
It would be possible if one knew in advance which model of the Titmus was in use, and also knew for sure that the color slide was the original and not a replacement. As you can see, the variables are huge.
