Visual Disorder Atlas can help you identify and communicate a vision problem you are experiencing.

With the help of more than 40 interactive illustrations, you can easily identify, describe, and communicate your visual symptoms, which allows a quicker and more accurate diagnosis. 


Identify and describe vision problems

There are many kinds of visual symptoms, such as floaters, drifting scenes, and warping, just to mention a few. Some symtoms are quite harmless, while others  need to be taken seriously.


Correct interpretation begins with good descriptions, but describing visual symptoms using just words can be difficult. That is where the Visual Disorder Atlas  can help.


Visumetrics´ Visual Disorder Atlas app, with its pictorial library, enriches verbal description of a visual symptom. Most of the 40 illustrations are interactive and animated, and they help you describe what you are experiencing. With the aid of a picture or animation, precise communication with medical experts is made easier. 


And the quicker, and more accurately, you can describe the symptoms you are experiencing, the sooner treatment can start, if needed.


Available as a free trial version and a fully functional paid version.


Researchbased app

Visual Disorder Atlas was compiled by Professor Lars Frisén, MD PhD, at the University of Gothenburg, Sweden. It builds on thousands of descriptions provided by patients with vision problems.
